    XHD Leaf Springs* (Original Equipment)
    These extra heavy-duty springs are just like the bias springs that were stock on 1968-72 A-Body with high-performance 340 engines and 1967-71 B-Body and 1970-74 E-Body with 440 or 426 engines. They fit 1964-75 A-Body, 1966-72 B-Body (22" front, 36" rear), and 1970-74 E-Body regardless of engine size. Front bushings installed.

    These springs control torque roll, providing equal bite on rear wheels and eliminating axle windup. The rear doesn't lock up; it moves and keeps tires planted. Rear springs have a 20" front segment & require a longer hanger bracket for B/E/F/H-Bodies (not included). A-Body uses standard brackets.

    Oval Track Leaf Springs*
    These reissued springs are ideal for oval track vehicles and widely used on dirt track race cars. 20.5" front, 35" rear. 120 pounds-per-inch spring rate.

    Give your ride the suspension upgrade it deserves—Mopar Performance Leaf Springs are engineered for classic Mopar cars that demand strength, stability, and stance in equal measure. Whether you're restoring an A-Body, B-Body, or E-Body, these springs are built to bring back control and confidence on the road or strip.

    These leaf springs tackle common issues like axle wrap, sagging rear, and inconsistent traction under power. Designed to control torque roll, the mopar a body leaf springs in this line deliver equal bite to both rear wheels—no more one-wheel hopping or uneven launches. They keep the rear end planted, allowing your tires to grip when it counts most. Recent offerings include extra-heavy duty (XHD) variants that mimic stock bias springs for high-powered setups, plus Competition and Oval Track styles for those pushing limits.

    Built from durable, fatigue-resistant spring steel with properly sized leaves and factory-style bushings, these mopar leaf springs offer a strong foundation without sacrificing ride quality. All springs are sold individually, giving you flexibility for replacing just one side or upgrading both ends without overbuying.

    Fitment covers a wide span of Mopar models from the mid-60s through early 70s, with spring lengths and hanger configurations matched for A-, B-, E-, and F-Bodies. Whether you want to restore OEM ride height or dial in performance for drag or oval track weekends, there’s a leaf spring style for your build.

    If you’re ready for better traction, less body roll, and a more confident rear end under acceleration, these springs are your ticket. Add them to your cart today and start driving like your Mopar means business.
