Direct mounting for radial caliper brackets create strong, zero flex platform for brake mounting. 

Front Coil Over System & Control Arms

QA1 Front Coil-Over Systems for Chevy C10 trucks are available with single or double adjustable coil-over shocks allowing you to change the valving of each shock to meet your specific needs, along with a variety of high travel spring rate options. Both types of shocks allow for ride height adjustability and are 100% dyno tested and serialized. All required coil-over hardware for proper installation is included. Systems are compatible with popular drop spindles, which will provide even more drop when used with this system.

QA1's C10 upper and lower control arms feature a 12 gauge steel tubing construction for increased strength and are powder coated black for long-lasting durability. In addition, control arms come equipped with performance ball joints and low-friction, maintenance-free polymer bushings for added performance. This kit can add up to 7 degrees of caster for more stability and allows for precise camber adjustment in a lowered truck.

  • Adds up to 7 Degrees of Caster
  • Allows for More Camber Adjustment
  • Proudly Made in Lakeville, MN USA!

Rear Coil-Over Conversion System, Double Adjustable

Convert your truck from a coil-spring rear suspension to coil-overs. The coil-overs are relocated to the outside of the frame rail, closer to the wheel, providing more cornering stability and allowing room for popular aftermarket rear fuel tanks. The full-length, adjustable panhard bar with multiple mounting locations corrects roll center geometry to accommodate drop. 


*This Brake Kit may fit 16-inch wheels. Please refer to the wheel clearance diagram to check to see if it will fit your specific wheel.
