No matter your performance goal or your vehicle, there’s a good chance Summit Racing Equipment carries a rear suspension kit to suit your needs. Tighter handling from your modern muscle car? Done.

And, if your goals include hard launches and fast, consistent 1/4-mile performance, look no further.
Coil Spring Packages
The simplest rear suspension kit for coil-sprung cars replace your factory control arms with stronger, stiffer tubular parts. Many are adjustable-length, and may feature a combination of polyurethane or Delrin® bushings and spherical bearings to reduce deflection and binding, and eliminate wheel hop. These kits may also include springs, shocks, coilovers, panhard bars, sway bars, torque arms, hardware, and more.
Leaf Spring Packages
Similar packages are available for leaf-sprung cars. They include higher-rate springs that are de-arched for a lower ride height, heavy-duty shackles, stiffer bushings, and high-performance shocks. These kits improve your stance and handling without altering your suspension configuration.
Conversion Kits
In more extreme applications where the OE setup might not cut it, conversion kits are available to install 4- or 6-link suspensions in place of leaf springs, add strength and adjustability to your factory truck arms, and even eliminate your conventional rear axle altogether, replacing it with a cutting-edge independent setup.
