I just thought about it but if the RC lift is anything like my old 2 inch BDS spacer lift you won't need bump stop spacers. The actual lift spacer mounts on top of the cool and acts like a bump stop spacer pushing the bump stop down farther. I'm running bump stop spacers because I swapped out the spacer lift with longer coils and when initial installed you put the bump stop back in the factory location. But since the coils are longer you really need to add a bump stop spacer especially when running 33s

What diameter did you use?

Here's 2" spacer 3" diameter: http://www.summitracing.com/parts/PRA-BB02/
and 2" spacer 2" diameter: http://www.summitracing.com/parts/PRA-MB02/

I believe mine are 2 inch diameter. I'll measure the extra spacers tomorrow that I have in my garage. Either way it doesn't matter which diameter you go with. The cup for the bump stop was larger than my spacers in diameter and it would probably look better with a wider spacer.

Wondering if the 3" would be too large for the upper spring isolator to fit over. My aluminum rod is 3" diameter so it would be cool if I just have to slice a few pieces off and drill the hole, and not have to turn it down to 2.5 or 2" diameter.

Here is a pic of the bump stop spacer installed.

I think I'll wait till its lifted to flex it out and see if I will need to do anything to fit 285's.

I'm almost positive you will be ok with just the RC lift because it acts like a spacer.

Good to know, one less thing I have to worry about.

I'm rubbing my fenders real bad on the RC lift and 285's. Probably going to extend the bump stops as well.

I have the RC and I run 285/70. Only place I rub in the AC lines the run the the rear on the passenger side. That's only when I hit bumps though.

The RC spacer "cups" the bump stop mount and therefore doesn't lower it down as much. IIRC the bump stop is less than 1/2" lower than factory.
