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 offers bolt-in Rear Coil-Over Conversion Kits for 1964-1972 GM A-body vehicles. These kits include specially designed USA made mounting brackets and single or double adjustable aluminum shocks, high travel springs and all necessary hardware. 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 ride height adjustability. Multiple spring rate options are also available, and have been successfully tested in various applications, from casual street driving to hard core race applications. With our highly popular adjustable front coil-over kits and the addition of the rear coil-over conversion kit, you can now get a complete suspension makeover for both ends of the vehicle. 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. Conversion Kit Note: Later model vehicles tend to weigh more on average. Please take this into account when ordering springs.
