QA1 R131-170 Rear Coilover Conversion System 73-87 C10 GM 12-Bolt 170 lb/in Single Adjustable

The QA1 R131-170 is a complete rear coilover suspension conversion system engineered specifically for 1973-1987 Chevrolet C10 trucks equipped with a GM 12-bolt rear differential. This all-new, engineered-from-scratch rear system allows C10 owners to add modern performance without removing the bed of the truck.

Innovative Torque Arm Design:

QA1 engineered a unique bolt-in torque arm design that maximizes performance without the inherent binding issues of other 4-link systems, providing superior control over suspension movement for a smooth ride and great handling characteristics. Installation requires no cutting, welding, or other fabricating.

Adjustable Ride Height:

This adjustable coilover system offers 4 to 7 inches of adjustment below stock height. The system features single adjustable twin-tube coilover shocks with 170 lb/in spring rate, providing a soft ride quality ideal for street use. Pair this rear system with QA1's front system to have ride height adjustability on all four corners.
