Now you can easily give your C20 or R20 truck adjustable ride height, adjustable shock valving and improved geometry. That translates to a great stance with 1-3” of drop (up to 6” of drop with popular drop spindles), improved ride quality and significant handling gains. Plus, keep your 8-lug wheels.
You can easily install this kit in your driveway or garage with basic hand tools. No welding required. Everything is included, all the way down to the hardware.
Single Adjustable Shocks
This kit features single-adjustable shocks, giving you 18 clicks of valving adjustment. This gives you a very simple way to adjust your shocks without taking them off the truck. You can simply soften or stiffen the ride by turning one knob.
QA1 shocks are 100% dyno tested and serialized. Components included in these systems are proudly made in the USA at QA1’s Lakeville, Minnesota facility.
Fitment Notes
- Total drop range depends on wheel/tire fitment
- Requires spindles that use 1971-1986 C20 Ball Joints
The general rule that you can abide by is the heavier the coil the heavier the motor. A V6 or Straight 6 motor will generally use the lighter spring rates. The middle of the road weight will be set for your small block or LS applications, and the heaviest coils will be reserved for the big block motors. Now these are not rules set in stone. If you have a small block and are looking for a little better ride quality you can opt for the lighter coils to achieve that. In the same sense if you are working with a straight line or DRAG racing application you may opt for the light coils as well to achieve the weight transfer you need to get that good launch. When you are looking at the spring rate on the rear it's pretty simple. If you are looking for a better ride quality go with the lighter coils and if your application is more performance driven select the stiffer spring rate for handling. Don't get too stressed on ensuring you get it right the first time. The coils are easily interchangeable and are not too expensive so if you decide the spring rate you have chosen isnt quite right give us a call and we can get you a different set. If you are unsure give us a call. We are happy to help.
