With this all-new, engineered-from-scratch rear system, 1973-1987 C10 owners can add modern performance to a pickup that was designed for utility-all without removing the bed of the truck. QA1 engineered a unique bolt-in torque arm design that maximizes performance without the inherent binding issues of other 4-link systems. This provides superior control over suspension movement, resulting in a smooth ride and great handling characteristics. Dialing in the stance will be easy with the adjustable coil-over system - 4" to 7" of adjustment below stock can easily be achieved. Pair this rear system with QA1's front system to have ride height adjustability on all four corners, giving you that perfect level stance. Everything you need is included, all the way down to the hardware. All components included in these systems are proudly made in QA1's Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.

Manufacturer's Warranty — QA1
QA1 warrants this product to the original purchaser to be free from defects in material and workmanship for one year from the date of sale. A separate limited lifetime warranty covers only QA1's select shock and strut lines (Stocker Star, Proma Star, Ultra Ride and Aluma Matic) and requires registration at QA1.net/Warranty within 30 days of purchase. QA1 makes no other warranty, express or implied. Coverage does not apply where the defect results from improper or abnormal use, negligence, vehicle accident, incorrect installation or maintenance, or where the product has been repaired or altered in any way. QA1's liability is limited to repair or replacement of the defective product at its option; consequential and incidental damages are excluded. A claim needs an RMA number issued by QA1 — tag each item with the part number and a description of the defect — and the customer pays shipping to QA1 for inspection.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by QA1. Contact us if you need help with a warranty claim.
