Default How did you mount your Rear AFCOs??

I got some Madman brackets with my shocks your supposed to weld to the shock mounting bracket on the axle then bolt the shock to the madman bracket. I really didnt want to weld it on so I just tuned the shock and mounted it up the normal way with a grade 8 bolt and a spacer. The adjustment **** on the shock does clear the UMI drag bar but its kinda close. Do I need to be worried about side to side movement on the sway bar hitting the ****?

I know I've read a lot about people killing them, I'd use the bracket just to be safe.

Default shock brackets

You need to use the brackets,it keeps the shocks from going into a bind upon launch,madman fixed the design gm couldnt.

I made a bolt on bracket similar the one above... either welded or bolted, you need the bracket or you will damage the shocks...

Used splined wheel stud. Pressed into the bracket , then splines extending past the shock mount engage in the housing shock mount when tightening down.

Im making some billet alum bolt in brackets. We made them out of a solid block anyone think alum might not be strong enough? Its like triple the thickness of the org weld in bracket. I like the wheel stud Idea also.

Ya I just decided I didnt want to weld them. The only welder I had available was a flux wire welder and I just didnt trust it to penetrate deep enough. Then I just started thinking about a bolt in application.
Heres the bracket b4 the final adjustments and mounting. We had to mill down the bolt head and the inside of the bracket just a bit so the shock body didnt hit anything.

Looks like it would work to me, What is the benefits to going coilover than the shock and spring. (height adjustment only) or is there a benefit for takeing it to the strip?

lol, you had access to a mill but not a welder? I can't say I would trust aluminum there, but hey if it works, it works right?

We had a MIG and TIG at the shop but no way to get the car there, or the welder to the garage. Plus I decided I wanted a bolt in application. The machine shop owner thinks the alum will be strong enough thats why we went so much thicker with it over the supplied steel brackets.
