Question Trailing arm crossmember question?

Looking for a little advice. I am planning to use a 4" x 6" static drop from ECE. I have added a 2 1/2" notch and exhaust pass through on the crossmember. I may go 4 1/2" x 7" using a block in the back.

After looking at many builds and aftermarket crossmembers I was wondering if it would be a good idea to remove the trailing arm brackets and flip them upside down and bolt them back on, would have to drill 2 holes. Seems this would help with pinion angle and also allow a spacer in between the bracket and crossmember if the wheel base needed to be lengthened. The aftermarket crossmembers appear to have the trailing arms mounted higher and this seems like an easy way to achieve the same results without buying a new crossmember

Any thoughts on this, has anyone done it before? Will I have other clearance problems?

Thanks, Glen

Re: Trailing arm crossmember question?

I changed my rear suspension from leafs to coils and thought about doing that since i was going to use at least 6" coils or bags. I bolted the brackets on upside down and it actually raised the truck because it raised the arm closer to the frame. I thought that it would help with driveline angle but it wasn't worth raising the truck.

Re: Trailing arm crossmember question?

Thanks, I was wondering if that would happen and be noticeable. It basically levers the axle with the fulcrum being the spring. Did you change it back? I figured I could counteract the raise with a lowering block.

Yeah I changed it back, I didn't want to use blocks. Now I will have to use blocks to lower it down enough if I don't use bags to make it look right with the front
