Just bought a 25 z71…. I love it…. Buuuut my two boys are over 200lbs. When i have the third row seat, dog and cooler in the back, the rear end sags and drags on the trails. I put air bladders in my older ‘burbs rear coils to slow the compression. Any idea for the new rear ends?

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

I don't believe that should happen. Do you have the Four-Corner Air Ride Adaptive Suspension on your truck? If yes, there should be rear air assist which should lift the suspension to compensate for increased rear storage load conditions.

Can't you lift the truck 2 inches when going off-road? Or did they tie that into running in 4LO?

This does not have adaptive air ride…. Just a coil over strut type shock…
You are kinda screwed then. Why they ever got rid of the rear auto level with the sprung suspension is completely beyond me. Thats a bad deal.

These new ones just dont seem to hold a load very well. And there isnt really anything for aftermarket available.

I have seen an aftermarket air bag setup that apparently can replace the factory strut setup, but that will also require other equipment like air compressor and controls and whatnot. I have not seen anybody do this yet.

Could lift the rear an inch or so with a shock tower spacer but you'll be left with a weird rake angle when unloaded. How about this, Bilstein 5100's which will greatly increase damping and add in that adjustable sway bar you can find somewhere in these forms. Between the two you could reduce bouncing and one side from over compressing on the trails.

Wish I installed the 5100's the day I purcashed the truck.

New shocks can increase dampening, but it will do nothing for the squat though.
