Cupped Lower Control Arms - What bag? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Good morning guys.

So I've been on air for a few years now and I've always run 2600's front and 2500's in the rear. This is just a manual valve setup, very simple and easy. But I've recently noticed some wear on the bags in the front so I swapped them out with some spare 2600's.

It looks like the bags are slightly rubbing during drive time. They've lasted three years so far so not overly concerned at the moment. But I am curious what size bags do others run with cupped arms? I've heard some people running some slammed specialties bags but would like to see how the clearance is and all that jazz.

Thanks everyone.

Most run 2600 on the front.

Slam Specialties bags don't balloon out as much as others do. They are also slightly stiffer when compressing empty (compared to a Firestone of equal size).

I run a set of Slam Specialties SS-7 up front. The internal bump stops provide some insurance.
