Speedtech Performance USA AFX Performance Spindles
Looking for the ultimate set of performance spindles? Speedtech Performance AFX Performance spindles are here to get the job done! GM musclecars are known for having poor geometry from the factory. They rode relatively smooth and did well in straight line drag race situations, but high-speed cornering was less of a consideration in their designs. With today's technology, correcting these issues with control arms helps, but is only part of the equation. Speedtech and ATS have taken an entirely new approach to improving the less-than-optimal factory suspensions of the A, F, X, G and B body platforms by scratch-designing the focal point of the steering and suspension geometry: the front spindles. They will drop your ride height 1 in. for a more aggressive stance and lower center of gravity. Relocated steering arm mounting points are custom-designed for each individual vehicle to improve Ackerman and bring bump-steer numbers down to nearly zero. The spindles feature a Corvette ZR1 sealed, maintenance-free hub; it's heavy-duty, and the large bearing pack offers a stronger load capacity--able to handle the abuse of street and track driving. Speedtech Performance AFX Performance spindles and the ZR1 hub combination do not alter the factory track width or bolt pattern, allowing standard wheel fitment. Brake mounting is based on the C5/C6 Corvette and accepts factory Corvette brakes or packages from multiple manufacturers, including Baer, Wilwood, and others.

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. RideTech HQ Series shocks offer an industry-exclusive 1,000,001 mile warranty. RideTech is confident that TruLink is the most comprehensive bolt-on rear suspension system ever offered. It's also the most versatile design on the market. As your needs and budget grow, you can add matching HQ Series front shocks, StreetGRIP high performance coil springs and an adjustable MuscleBar™ rear sway bar. Down the line, you can upgrade to adjustable coilovers or Shockwaves with matching TruTurn front suspension.
