Description

Here's an easy way to convert your stock rear suspension to a coilover suspension. You get everything you need with these QA1 Rear Pro coilover systems, from shocks to nuts and bolts, complete installation instructions, and even decals!

Product Overview

QA1 now offers bolt-in rear coil-over shocks for 1978-1988 Monte Carlos, Grand Nationals, Regals and Cutlasses. These shocks are available in single or double adjustable valving options. Single adjustable shocks provide 18 positions of simultaneous rebound and compression adjustment while QA1's double adjustable shocks provide 18 positions of compression adjustment and 18 positions of rebound adjustment, for a total of 324 possible valving combinations. These shocks also utilize a fully threaded body allowing for the use of after market springs.

These lightweight billet aluminum coil-over shocks are made in the USA and offer easy, bolt-in installation and ride height adjustability. They are 100% dyno tested and serialized and serviceable and rebuildable by QA1 authorized service centers. Used in drag racing, street performance, autocross, road racing and street rod applications.
