Up for sale is a very slightly used set of four Performance Unlimited / QA1 single adjustable shocks and two sets of springs. Paid $1250, asking $850.
I purchased these from Performance Unlimited in an attempt to address a unique ride height issue and failed to take proper measurements before purchasing them. They do not fit my application. I installed these shocks/springs, drove around the block, changed springs, drove around the block again, then removed them - very slightly used. I have pursued an alternative solution, so this set are up for sale.
Included are two sets of four springs: 350lbs (front=7", rear=10") and 450lbs (front=9", rear=10").
Please note these shocks have 1/2"ID (not 12mm) spherical bearing mountings, however these can be easily changed to 12mm to fit most SPFs.

When I purchased the springs/shocks, the 450lbs springs (F=9", R=10") were suggested. I installed them, and for me:
1. To get the ride height close to where I wanted it, the spring perches were on the very last threads of the shock body. Performance Unlimited said that that is the way his is set up, so this is ok, but I was not happy with ride height and needed to go a tad lower (and could not).
2. The 450lbs springs were too stiff for me.
So, I purchased 350lbs springs from Summit Racing, and when I did, I saw they had the same front spring in a 7" length, as well as the 9". Since there is around 4" of threads on the shock body, I knew that there was plenty of threads to install a 2" shorter spring. And I was right. To get to the ride height I wanted, the 7" spring worked fine. (BTW, to keep the stock ride height the 7" spring also works without a problem).
For me, getting to the ride height I wanted meant getting either new shocks, getting the QA1's machined, or getting my old Koni's machined. I chose to machine my old Koni's, and I'm happy with the results. This is why I have these shocks for sale with two set springs with two different front spring heights.
