RideTech 1970-81 Camaro/Firebird Complete CoilOver Suspension Systems
The RideTech 1970-81 Camaro/Firebird Complete CoilOver suspension systems include everything you need to completely upgrade your existing suspension. The package contains front upper and lower StrongArm control-arms, front MuscleBar, a rear Bolt On 4-Link, and 4 HQ Series CoilOvers shocks for every corner of your vehicle. The benefit of buying a complete suspension system is that it takes all of the guesswork out when purchasing a new suspension. RideTech has spent hours collecting data to find a perfect spring rate and components for your vehicle's performance and ride quality. RideTech Complete CoilOver systems include: - Upper StrongArms feature corrected ball joint angles for the tall spindles. The upper ball joints have been moved back to allow for additional caster setting to improve high speed stability and steering feel. Offset slugs are also available for additional caster. Injection molded Delrin bushings with 13% Teflon are used to reduce deflection and stiction. - Lower StrongArms feature a double sheer lower mount for increased strength. We have also dropped the lower shock mount to increase suspension travel and moved the lower ball joint forward to increase caster settings while keeping the wheel centered in the wheel opening. Injection molded Delrin bushings with 13% Teflon are used to reduce deflection and stiction. - HQ Series CoilOver shocks utilize an impact forged aluminum body and Monotube design to deliver excellent ride quality and handling. They allow fine tuning of the ride quality and handling. The rebound knob is located at the top of the shock for under hood access. - Front MuscleBar helps to reduce body roll and creates room for wider front tires. It includes the PosiLink endlinks that provide immediate engagement between the chassis and control arms. - Bolt On 4-Link greatly improves traction, handling and ride quality. Installation does not require the any major modifications to the floor pan and requires only minimal welding to the axle tube. Equally important, the unique design addresses production variations and frame rail thickness issues that are common to the second-generation F-Body platform. Works with minitubs. The R-Joint rod ends combine the best qualities of low friction movement, lateral stability, full range articulation, and quiet operation into one special bearing that is as home on the street as it is on the racetrack!

Energy Suspension Body Mount Bushings
Aluminum body mounts are too harsh for street use and tend to break, causing damage to other parts; while factory rubber mounts are so soft that they crack, distort, crush, and often fall off. Energy Suspension's specially formulated polyurethane body mount sets combine the best qualities of both—they're soft enough for a smooth ride, and yet rugged enough for the most demanding road or track. Most have a steel ring molded into the end for added durability. Hundreds of kits are available; order the model recommended for your application.
