All you lowered GMC owners...... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know this has probably been discussed before...... but what is the lowest you can lower with leafs/shackles/flip kit/cnotch.... before the rear end housing touches the bed. I am trying to figure out a new combo for my truck with supplemental air bags for load leveling or convert to all Porterbuilt coil set-up Thanks in advance.

The rear end will hit the bottom of the bed at the same height as a coil rear.

About 7in, Id start to be concerned. It just depends if you plan to do any hauling with it, how you plan to drive it, etc.

I have a PB coil setup on my black truck (link in my signature) if you want to check it out.

Yeah, 7" is what I thought I remember some of the guys saying. I know every truck is different and whether it is a long or shorty too. I know I could do a flip kit and run my shackles and get 7", but I would have to get some factory height leafs. Mine are the ECE 4" drop...... or just bite the bullet and PB the whole damn rear end so I could bag it.

I have 7 inches on mine no C-noth or flip kit!

What did you do Tim? 5" leafs and 2" shackles?

To give you a visual, Two inches higher than this with a 235/75r15 tire
My rear diff is 2" into the floor.
Not sure how much it's lowered. Fender lip as at about 23.5" here

I raised my front spring mounts to lower an extra inch. Left stock holes for adjustability.
