Thread: Reduce rear sag when towing?

Reduce rear sag when towing?
Are there any options out there available to reducing the amount of drop when towing in the rear?
Can we just add stronger leaf springs in the rear, or do I do something like airbag suspension modification for towing?
I'm just curious because I'm doing the leveling kit and I don't want my truck to ride lower in the rear while towing.

Do you have load bearing shocks? I have the shocks with springs over them (load bearing) and my truck doesn't sag much.
If at first you don't succeed, chances are, you are using too small of a cheater bar

Nope, unfortunately my truck only came with standard rear shocks with leaf springs. Where can I find these shocks you're talking about? They sound very good, hopefully not too pricey either.

One issue with overload shocks (also described as coil overs) is they stiffen the ride, these new Chevy trucks ride nice so it's a shame to ruin that comfort factor.
You could also use Add A Leafs (AAL's) and again it'll ruin the ride.
The one option you have to maintain the factory ride and stabilize the rear end for towing is air bags, Firestone makes what I feel are the best bags in the buisness but theres a few other manufacturers on the market too.
Air bags can be intalled as a full kit with airtanks and an onboard compressor (thats able to use air pressure for other chores) or you can install just bags that you'll need to charge up with air everytime you tow then let some pressure out afterwards.
Yes airbags are more expensive, but in my opinion if you put many miles on your truck you'll quickly tire of the stiff suspension other methods offer.

Stay away from the load bearing shocks. Shocks are meant to damp the movement of the springs, not help support the load. If you use them long enough and haul heavy enough loads I've seen them rip the shock mounts off the frame and or axle. On my Suburban I use the Firestone airbags and love them. When I tow I just pump up the pressure to level the truck and go. When I'm unloaded I run them with no air and enjoy the factory ride. Also, if you're pulling heavy trailers you should be using a equalizer hitch. They will also help level the truck out when towing and some designs have sway control built in.

Thanks for the input guys, looks like I'll be going with the airbag set up. I am a little on the lazy side and would rather have the luxury of having a compressor mounted into the bed of my truck. I'll be looking into one of those hitches as well, my main concern besides looks is I feel that the truck will be a bit more stable riding close to factory height without the rear sagging lower than the front too much.
