View Full Version : Coil over rear shocks

I have purchased a set of rear coil over shocks from Spirit but am having difficulty finding the spring rate of them. Does anyone know what they are rated for? I have them on a steel bodied car and they seem a bit light.

I have the spirit coilovers and based on the PN that was on the box, they are rated at 150 pounds ( QA-1, pn 12CS150 ). They may be too light for a steel body.

We use 150 pound spring rate.

Which QA1 Coil Over body does Spirit use? I have one of the early frames that uses the same mounting bracket for the front and rear hairpins, verus the new frames where the rear hairpin bracket is lower than the front.

The Part # on the QA1 shock is ALN5855b abd the spring is 12c5150. Without taking a tape to both shocks I'll say the QA1 shock is about 2" taller. They are about $100.00 more but they are a pretty nice shock.
