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.

Ridetech TruLink Rear Suspension Systems
Tune up your chassis with Ridetech TruLink rear suspension systems and achieve significantly better handling and launch characteristics, along with dramatically improved ride quality and service life. The comprehensive system features heavy-duty tubular control arms equipped with patent-pending R-Joints plus application-tuned HQ Series adjustable shock absorbers. TruLink replaces your car's flex-prone stamped upper and lower control arms with precision-welded tubular steel Strongarms constructed from heavy-duty 1.5 in. O.D. DOM steel tube. The end result is less flex for more predictable handling and launch characteristics. Strongarm rear trailing arms are precision welded at our Jasper, Indiana factory and then powder-coated for long-lasting appearance. Ridetech installs patent-pending R-Joint rod ends and bearings for noise-free, high articulation movement with zero stiction. R-Joints eliminate the binding, stiction, noise and vibration associated with poly bushings offered in most aftermarket control arms. R-Joints never need lubrication and have exceptional wear resistance. For ultimate articulation, the TruLink system features press-in R-Joints for your axle to upper control arm attachment points. This critical feature is often overlooked in the upgrade process. The final piece in the TruLink system is a pair of Ridetech HQ Series adjustable monotube shock absorbers. They are custom-valved specifically for your vehicle's platform with modern tires. Ridetech provides rebound adjustment to help you fine tune compliance. With a few turns of the adjusting knob, you can tune rebound damping to suit both your car's needs and your personal preferences.
