Adjustable Rear Upper Control Arms for 66 GTO

[old66tiger]

I have adjustable rear uppers on my car now but I was looking to replace them with uppers that have spherical joints. I was going to go Ridetech but the only offer a single adjustable and pulling the arms out to make adjustments does not appeal to me. Anyone using the UMI arms with the roto-joints? Any reports on longevity?

I can't say anything about the UMI arms' longevity yet, but I can say their quality is top notch. Heavy duty materials, nice welds, easy to adjust, and their roto-joints are a great design.

I have full roto's on my chevelle, uppers and lowers. I love them. They also came out with the upper housing end roto-joints too. I will probably switch to those this year as well.

What makes the Currectrac arms better than the UMI arms?

Hey guys. Hey David. Thanks for the shout out.

Our Roto's are very durable and rarely have any trouble. They are made entirely in our building of US materials including DuPont Delrin (150 formulation). We source US Steel.

Roto's swivel like a rod end yet still provide some cushioning.

Our upper housing bushings install quickly and easily. A gentle press fit and a Spirolock holds them in place.

If you have any questions let me know. Happy to help.

X2. I always wonder about stuff like that. Are you paying for a name at that point? I know Currie has a good reputation, but there has to be a point where the differences are so minor. The one thing that I like better about the UMI is the use of chrome molly. I know aluminum is strong, but in my mind, when it comes to suspension parts, especially ones that have threaded joints, steel seems to have an alluring appeal.

Will the Roto's fit into the 65-70 B-body arms?
