Im in the hunt for some nice rear control arms, both uppers and lowers. Just need boxed lowers and adjustable uppers. I found a set of both boxed and adjustables through both companies. Ill end up spending 200 more bucks through metco but to me it sounds like there alot stronger being billet and all. I know alot of guys use UMI and they work well. Ill be doing polyurethane bushings that are included. Whats your guys opinions?
 
My opinion is whatever company you go with, do not go with all poly bushings in the rear. Poly bushings with the stock C4L rear suspension has a ton of bind. Using spherical joints on the frame side is really worthwhile.

x2..I have the UMI uppers and lowers with the Roto joint
 
i used spohn performance 615 uppers and 615 lowers. they are both tubular, adjustable with spherical bearings. there is no binding with them. so far no problems.

Our arms are 100% Made In Philipsburg, PA - USA and are bulletproof. Our Roto-Joint is made in-house here as well.

Here's the Roto upper:

And here's the selection of lowers:

Lots of articulation choices for your non-binding needs.

Let me know if we can help.

thx

The reason I like the Roto joints over the spherical joints is the Roto joints are not harsh like the spherical joints. I think the Roto's are similar to a poly bushings in performance
