Just like QA1’s popular C10 coil-over system, this kit easily gives your C20 or C30 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.

Double Adjustable Shocks

This kit features double-adjustable shocks, giving you 18 clicks of independent compression and rebound valving adjustment. These are great if you who really want to fine-tune your shocks on the street or plan to track your truck.

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.
