Rear control arms
 

I'm starting to turn my 88 c1500 into a performance street truck and the first step is building a solid rear end. I plan on using the stock 8.5" 10 bolt but I plan on converting the suspension to a coil over set up and mounting some upper and lower control arms to the differential/axel housing. Since the rear end was not originally equipped I'm having a tough time finding them designed for the truck. Any suggestions other than just custom fabbing some adjustable ones in??

Here are a few links to 4 link set ups.
I would think any could be done with coil overs.

Thanks. using 4-link instead of control arms or trailing arms completely altered my search results.

Anyone here have a preference on axle brands for an 8.5"10 bolt to hold about 450 hp??

Moser.

Any specific axles you have used and how much horse power do you have behind them?

Re: Rear control arms
 

The moser axles were in a El Camino with a 400sbc 10 bolt rear end. I have no idea how much power the car made. If I had to guess I would put it conservatively at 425hp and close to 500tq.

I also had Superior Axles in a Mustang with a 8.8 rear end. Engine made 415hp/455tq. So they saw use everyday.

PS I would make sure you do a very detailed build of the 10 bolt. Also get a cover with bearing supports in it. It can break the caps no prob.

IMHO if you plan on putting any power to this project I would think about stepping up to 12 bolt or 9" with 31 spline axles. They should still be in abundance in the bone yards.

I am considering changing the whole rear end but I keep reading that the 8.5" 10 bolt rear end can handle platforms with < 500 hp no problem
