PART MISMATCH: Leaf springs are TRUCK/SUV/COMMERCIAL VEHICLE component for live rear axle suspension. Dodge Dynasty is FWD MID-SIZE SEDAN 1988-1993 with NO leaf springs - uses MacPherson struts with coil springs front and independent rear with coil springs.
Dodge Dynasty context: Chrysler's mid-size FWD sedan produced 1988-1993 (6 years US production), positioned between K-Car compact sedans (Aries/Reliant) and larger Chrysler New Yorker. Platform: Chrysler AA-Body (extended K-Car FWD unibody architecture - different from 1970s C-Body RWD sedans). Sister vehicles: Chrysler New Yorker 1988-1993, New Yorker Salon (premium AA-Body sedan).
Engines: 2.5L K-Car I4 base (~100-105 HP, Chrysler's famous K-Series engine from K-Car heritage), 3.0L Mitsubishi 6G72 V6 most common (~141 HP, sourced via Chrysler-Mitsubishi joint venture partnership documented in earlier batches), 3.3L Chrysler V6 higher trim (~150 HP, Chrysler's own V6 design). A604 Ultradrive 4-speed automatic transmission (NOTORIOUS reliability issues early production, class-action lawsuit settlement). FWD only, 4-door sedan only.
Suspension: MacPherson struts front with coil springs integrated, independent rear with coil springs (trailing arm or twist-beam architecture typical of FWD passenger cars). NO LIVE AXLE that would require leaf springs. Discontinued 1993 - replaced by LH Platform vehicles (Dodge Intrepid, Chrysler Concorde, Eagle Vision, Chrysler LHS) with industry-leading 'cab-forward' design.
Why leaf springs don't apply: FWD sedan architecture, no live rear axle, no leaf spring provisions, coil spring/strut architecture throughout. Customer likely needs different component (coil springs, MacPherson struts, shocks, control arms, sway bars, trailing arms) or has confused vehicle entirely (truck, SUV, older RWD sedan). Call (240) 301-0095.
Why This Part Doesn't Apply
FWD sedan architecture: Uses coil springs and struts
No live axle: Independent rear suspension
Passenger car design: Not truck/SUV
No leaf spring provisions: No mounting points exist
No aftermarket exists: No manufacturer makes for Dynasty

Why doesn't a leaf spring apply to my Dodge Dynasty?
LEAF SPRINGS are TRUCK/SUV/COMMERCIAL VEHICLE COMPONENT for LIVE REAR AXLE suspension. Used on: pickup trucks (F-150, Silverado, Ram), body-on-frame SUVs (1st gen Durango Batch 54 documented), heavy-duty vehicles, commercial vehicles (Dodge B-Series van Batch 53 documented). Function: multi-leaf steel pack mounted to live rear axle, provides suspension travel and load capacity. NOT used on FWD passenger sedans which use COIL SPRINGS and MACPHERSON STRUTS. Dodge Dynasty is FWD MID-SIZE SEDAN 1988-1993: (1) FWD unibody construction (not body-on-frame truck). (2) MacPherson struts front with coil springs integrated. (3) Independent rear suspension with coil springs (trailing arm or twist-beam architecture). (4) NO LIVE AXLE rear (independent wheels). (5) NO LEAF SPRING PROVISIONS anywhere on vehicle. (6) NO AFTERMARKET makes leaf springs for Dynasty. If you need suspension service on Dodge Dynasty, you need: front coil springs, MacPherson strut assemblies, front shocks (integrated with struts typically), rear coil springs, rear shocks (separate from springs), lower control arms, sway bars, trailing arms (rear). Call (240) 301-0095 to identify what you actually need.
What is the Dodge Dynasty?
The Dodge DYNASTY was Chrysler's MID-SIZE FWD SEDAN produced 1988-1993 (6 years US): (1) MARKET POSITION - positioned between K-Car compact sedans (Aries/Reliant) and larger Chrysler New Yorker. Competed with: Ford Taurus (1st-2nd gen aero era documented Batch 53), Honda Accord, Toyota Camry, Buick LeSabre/Century, Oldsmobile Cutlass Ciera. (2) PLATFORM - Chrysler AA-Body (EXTENDED K-CAR ARCHITECTURE, FWD unibody construction). Important note: this is DIFFERENT from 1970s Chrysler C-Body which was RWD full-size sedans. Dynasty uses modern FWD unibody architecture following K-Car heritage from Lee Iacocca's Chrysler recovery 1981+. (3) SISTER VEHICLES: Chrysler NEW YORKER 1988-1993 (premium twin sharing AA-Body), Chrysler NEW YORKER SALON (even more premium AA-Body sedan). Plymouth Acclaim was different smaller A-Body platform. (4) ENGINES: 2.5L K-Car I4 (base, ~100-105 HP), 3.0L Mitsubishi 6G72 V6 (most common ~141 HP, sourced via Chrysler-Mitsubishi joint venture partnership), 3.3L Chrysler V6 (higher trim ~150 HP, Chrysler's own design). (5) TRANSMISSION: A604 Ultradrive 4-speed automatic (NOTORIOUS reliability issues early production with class-action lawsuit settlement related to transmission failures). (6) DRIVETRAIN: FWD only (no RWD/AWD/4WD). (7) BODY: 4-door sedan only (no coupe, wagon, or hatchback). (8) DIMENSIONS: Length ~192 inches, wheelbase 104.3 inches, width ~68 inches. (9) DISCONTINUATION 1993 - replaced by LH Platform vehicles (Dodge Intrepid, Chrysler Concorde, Eagle Vision, Chrysler LHS) with industry-leading 'cab-forward' design. (10) LEGACY: Dynasty represents transition era of Chrysler from K-Car derivatives to modern LH Platform vehicles.
What is the difference between leaf springs and coil springs?
LEAF SPRINGS and COIL SPRINGS are FUNDAMENTALLY DIFFERENT SUSPENSION TECHNOLOGIES: (1) LEAF SPRINGS: (a) MULTIPLE STEEL LEAVES STACKED TOGETHER in long flat pack. (b) Mounted LONGITUDINALLY (parallel to vehicle length). (c) Both SUSPENSION FUNCTION (compression/extension under load) and AXLE LOCATION (positioning live axle laterally and longitudinally). (d) Heavy-duty, high load capacity. (e) Used with LIVE AXLE rear suspension (entire axle moves as one unit). (f) Applications: pickup trucks, body-on-frame SUVs, commercial vehicles, heavy-duty vehicles. (g) Pros: durable, simple, high load capacity. (h) Cons: rougher ride, heavier weight, less precise wheel control. (2) COIL SPRINGS: (a) HELICAL STEEL SPRING wound in coil shape. (b) Mounted VERTICALLY (perpendicular to vehicle direction). (c) ONLY SUSPENSION FUNCTION (provides spring force) - other components handle axle/wheel location (control arms, trailing arms, etc.). (d) Lighter, more refined, more compact. (e) Used with INDEPENDENT SUSPENSION (each wheel moves independently) and MacPherson struts. (f) Applications: passenger cars, modern crossover SUVs, performance vehicles. (g) Pros: smoother ride, lighter, independent wheel control, more precise handling. (h) Cons: lower max load capacity, more components needed (separate control arms), more expensive engineering. (3) MACPHERSON STRUT - combines coil spring and shock absorber in single integrated unit. Most common modern car front suspension. Used in Dodge Dynasty front. (4) WHY DIFFERENT VEHICLE TYPES USE DIFFERENT: (a) TRUCKS/SUVs use leaf springs because: heavy loads, towing capacity, body-on-frame architecture compatible, durability for commercial use. (b) PASSENGER CARS use coil springs because: smoother ride needed, lower loads, FWD architecture, modern engineering preferences. (5) FOR DODGE DYNASTY - FWD passenger sedan uses coil springs and MacPherson struts throughout. Has NO leaf springs. If you need Dynasty suspension service, look at: coil springs, struts, shocks, control arms - NOT leaf springs.
What was the Chrysler AA-Body platform?
The Chrysler AA-BODY was MID-SIZE FWD platform 1988-1993: (1) DEVELOPMENT - extended from earlier K-Car (A-Body) architecture established by Lee Iacocca's Chrysler recovery 1981+. (2) DESIGNATION - 'AA-Body' indicates EXTENDED A-BODY (Chrysler used letter codes for platforms: A-Body = K-Car compact, AA-Body = extended mid-size, B-Body = various rear-wheel-drive variants documented earlier, C-Body = various variants, etc.). (3) AA-BODY VEHICLES: (a) DODGE DYNASTY 1988-1993 (this listing's vehicle). (b) CHRYSLER NEW YORKER 1988-1993 (premium twin). (c) CHRYSLER NEW YORKER SALON (premium variant). (4) DESIGN APPROACH: (a) FWD UNIBODY construction. (b) Longer wheelbase than K-Car (104.3 inches vs ~99 inches K-Car). (c) Larger passenger space and trunk. (d) More premium positioning than K-Car. (e) Continued K-Car powertrain heritage but added Mitsubishi V6 and Chrysler 3.3L V6 options. (f) MacPherson strut front suspension with independent rear. (5) MARKET STRATEGY - filled GAP between K-Car compacts and larger Chrysler/Imperial premium sedans, gave Dodge mid-size sedan that competed with Ford Taurus and Honda Accord. (6) AA-BODY LIMITATIONS - aging K-Car architecture limitations: (a) Outdated styling vs new competitors. (b) A604 transmission reliability issues. (c) Conservative design vs Ford Taurus's aerodynamic revolution. (d) Limited power vs growing competition. (7) REPLACEMENT 1993 - Chrysler replaced AA-Body with LH PLATFORM (Dodge Intrepid/Chrysler Concorde/Eagle Vision): (a) All-new cab-forward design. (b) Industry-leading proportions. (c) More interior space. (d) More modern engineering. (e) Better engines (3.5L V6 modern). (f) Industry-leading 'cab-forward' styling that influenced other manufacturers. (8) AA-BODY LEGACY - represents transition era of Chrysler from K-Car derivative architecture to modern platforms. Useful 6-year run as transitional vehicle.
What was the A604 transmission problem?
The Chrysler A604 ULTRADRIVE 4-SPEED AUTOMATIC was NOTORIOUS for reliability problems: (1) BACKGROUND - A604 was Chrysler's first 4-speed automatic with electronic control, launched 1989 in Dodge Dynasty/Chrysler New Yorker, Plymouth Voyager/Dodge Caravan minivans, other Chrysler vehicles. Promised modern technology with electronic shift control. (2) PROBLEMS REPORTED EARLY PRODUCTION 1989-1993: (a) PREMATURE WEAR - transmissions wore out at 60,000-80,000 miles (vs 100,000+ miles expected). (b) ERRATIC SHIFTING - rough shifts, missed shifts, slipping during gear changes. (c) HARSH ENGAGEMENT - delays then violent gear engagement. (d) COMPLETE FAILURE - some transmissions failed entirely requiring replacement. (e) TORQUE CONVERTER ISSUES - lockup torque converter problems. (3) CAUSES: (a) Software/firmware issues with electronic shift control (new technology had bugs). (b) Insufficient transmission cooling. (c) Some hardware design choices that contributed to wear. (d) Warm-weather/heavy-use conditions worsened problems. (e) Aggressive shift programming. (4) FORD/HONDA CONTRAST - while Ford automatic and Honda automatic of same era were generally reliable, Chrysler A604 became byword for problematic transmission. (5) CLASS-ACTION LAWSUIT - Chrysler faced class-action lawsuit over A604 reliability. Settled with: extended warranty provisions, customer compensation, repurchase options for some affected vehicles. (6) IMPROVEMENTS - Chrysler progressively improved A604 throughout production: (a) Software updates. (b) Cooler additions. (c) Component redesigns. (d) Better fluid specifications. (e) Later A604s (mid-1990s+) became more reliable. (7) IMPACT ON DODGE DYNASTY - A604 problems affected Dynasty reputation. Some 1989-1990 Dynasty owners had multiple transmission failures. Sales reflected reliability concerns. Reputation never fully recovered before 1993 discontinuation. (8) LATER CHRYSLER AUTOMATICS - A606 (5-speed), A904 evolution variants, 42LE, 545RFE, ZF 8-speed eventually replaced A604 family. Modern Chrysler transmissions generally more reliable. (9) FOR USED DODGE DYNASTY BUYERS - check transmission service history carefully. Early 1989-1990 Dynasty with original A604 transmission may be high-risk purchase. Later production (1991-1993) generally better but still issue.
What is the LH Platform that replaced Dynasty?
The Chrysler LH PLATFORM was REVOLUTIONARY 'CAB-FORWARD' DESIGN that replaced Dynasty 1993: (1) LH = LARGE-H (Chrysler internal designation), introduced 1993 model year as replacement for AA-Body mid-size sedans. (2) CAB-FORWARD DESIGN - INDUSTRY-LEADING INNOVATION: (a) Wheels pushed to corners of vehicle. (b) Passenger cabin extended forward. (c) Hood shortened. (d) Trunk shortened. (e) Result: MORE INTERIOR SPACE in same exterior footprint. (f) MORE MODERN PROPORTIONS vs traditional 3-box sedan styling. (g) BETTER VISIBILITY from forward-positioned greenhouse. (3) LH PLATFORM VEHICLES (Direct Dynasty Replacements 1993+): (a) DODGE INTREPID 1993-2004 (mainstream LH sedan, direct Dynasty successor). (b) CHRYSLER CONCORDE 1993-2004 (premium twin). (c) EAGLE VISION 1993-1997 (sport variant, before Eagle brand discontinued). (d) CHRYSLER LHS 1994-1997 (premium top trim). (e) CHRYSLER 300M 1999-2004 (performance variant). (f) CHRYSLER NEW YORKER 1994-1996 (briefly continued name on LH). (4) ENGINES (Significant Improvement over AA-Body): (a) 3.3L Chrysler V6 (carried over). (b) 3.5L Chrysler V6 (new modern engine ~214 HP). (c) 2.7L V6 (smaller efficient option). (5) TRANSMISSIONS: 42LE 4-speed automatic (improved over A604), 41TE 4-speed. (6) MARKET IMPACT - LH Platform vehicles initially extremely successful: (a) Dodge Intrepid was hit with bold styling. (b) Chrysler Concorde won critical acclaim. (c) Industry-wide influence on cab-forward design. (d) Ford eventually emulated with 1996+ Ford Taurus (controversial oval era documented Batch 53). (e) GM responded with cab-forward designs in late 1990s. (7) LEGACY - LH Platform represents PEAK Chrysler product development before Daimler partnership (1998) and subsequent challenges. The cab-forward design philosophy influenced industry for decade. (8) SUCCESSOR - LX Platform 2005+ (Chrysler 300/Dodge Charger/Dodge Magnum) replaced LH with rear-wheel-drive return to traditional sedan proportions. (9) FOR PARTS - LH Platform vehicles use completely different components from AA-Body Dynasty. NO interchange between Dynasty and LH vehicles.
Could I have meant a different vehicle?
Yes, possible vehicle confusion if you searched for leaf springs on Dodge Dynasty: (1) MORE LIKELY YOU HAVE: (a) DODGE PICKUP - Ram 1500/2500/3500 has rear leaf springs (full-size pickup with body-on-frame), Dodge Dakota 1987-2011 (mid-size pickup with leaf springs), older Dodge D-Series pickup pre-1993. (b) DODGE SUV - 1st gen Durango 1998-2003 has rear leaf springs (Dakota-based, documented this batch vaz507), older Dodge SUVs like Ramcharger had leaf springs. (c) DODGE VAN - B-Series van or Ram Van had leaf springs (commercial van, documented Batch 53 vaz500). (d) CLASSIC DODGE - older RWD sedans like Diplomat (M-Body 1977-1989, prior to Dynasty's FWD era) had leaf springs rear, Coronet/Polara/Charger 1970s B-Body had leaf springs rear, Aspen/Volare F-Body had leaf springs rear. (2) NAMING CONFUSION POSSIBLE: (a) Dodge Dynasty (FWD sedan 1988-1993) - this listing, NO leaf springs. (b) Dodge Diplomat (RWD sedan 1977-1989) - HAD leaf springs. (c) These two might be confused due to similar 'D' names but completely different vehicles. (3) BEST STEP - call (240) 301-0095 with your actual vehicle (year, make, model, engine, drivetrain) and what symptoms you're addressing. We'll help identify whether your need is: actual leaf spring for truck/SUV/older RWD sedan (different vehicle), or different suspension component on your Dodge Dynasty (coil springs, struts, shocks). (4) DODGE DIPLOMAT NOTE - if you actually have Dodge Diplomat 1977-1989 (RWD sedan, M-Body, often used by police as 'Diplomat Cop' interceptor), this RWD sedan DOES have rear leaf springs. Diplomat continued the body-on-frame RWD sedan architecture into the late 1980s. Common with police agencies. (5) DODGE ARIES/RELIANT note - if you have K-Car Aries 1981-1989 or Plymouth Reliant 1981-1989, these are FWD compact sedans like Dynasty (no leaf springs).
