Product Description

The QA1 RCK52336 is a bolt-in rear coil-over conversion kit for all 1964-1972 GM A-Body vehicles, including the Chevrolet Chevelle, El Camino, Monte Carlo, Pontiac GTO, LeMans, Grand Prix, Oldsmobile Cutlass, 442, Buick Skylark, Gran Sport, and GMC Sprint. It replaces the factory rear shock absorbers with a pair of double-adjustable billet aluminum coil-overs, 150 lb./in. springs, specially designed USA-made mounting brackets, and all required hardware - everything needed for a complete bolt-in installation with no cutting or welding required. The threaded aluminum shock body allows ride height adjustment from 0.5 in. above stock down to 2.25 in. below stock for stance and corner balance control.

The double-adjustable valving delivers 18 independent positions of both rebound and compression on separate external knobs, giving 324 total tuning combinations to dial in the suspension for street cruising, autocross, or road course use. The 150 lb./in. medium spring rate is QA1's street-oriented choice for the A-Body platform - for heavier builds or more aggressive driving, QA1 offers the 175 lb./in. version (RCK52337). Note that the lower shock mount bracket is designed for stock 10-bolt and 12-bolt GM A-Body axle housings and may not be compatible with all aftermarket rear end housings - verify before ordering. All shocks are dyno tested and serialized and are eligible for QA1's Limited Lifetime Warranty upon registration before installation.
