Suspension options

Nuckfan · May 25, 2016

Hey guys, just took out my truck (2015 2500hd) with my slide in camper. The camper weighs in at 1655lbs wet. The rear squats about 3.5 inches when loaded. I've been researching Timbren bump stops and Torklift Stableloads. Not too sure which to go with. Just wondering if one is better than the other for "my" truck. Other than the squat in the rear, she handles well and ate the hills for breakfast.

I'm not familiar with either of those options, but if you're just looking to get rid of the squat, maybe have a look at air bags as an option too. I installed a set into mine, and I'm impressed with how they're working.

Had Timbrens on a 2500 HD worked well loaded. Unloaded did not like the ride. There was about 3/4 inch space between the Timbrens and the axel pad on on some roads had a jolt .

A few things - I think you are missing a number in your original post. At only 1600 pounds, it won't squat at all.

Are you using a weight distribution hitch?

I'm towing around 9,000 pounds and only have a little squat with my WD hitch.

I have truck camper and am running both upper and lower stable loads and airbags they work well together

The stable loads took a lot of the sway out the combo.

I think your missing the OP point... he's using a SLIDE IN camper, it weighs 1600 lbs, and when it's in... the truck squats. He's looking to reduce that. The use of a weight distribution hitch will not work in this situation as there's no trailer involved.

Air bags or helper springs. I used Super Springs on my last truck to help with sag and stability while towing and they worked great for five years. Once they're on there's no maintenance, unlike air bags.

My current truck has a much higher tow rating than my last one so I went with SumoSprings in the rear. They replace the factory jounce bumpers and have eliminated sag when hitched and smoothed the ride.

Based on my experience with a trailer if I had a slide in truck camper I'd look first at helper/overload springs or air bags.

Timbrens are by far the cheaper and easier route.

I figured I would start with timbrens and if I need to ill get stable loads at a later time and run both of them together. Timbrens should be here Friday.

Good luck with the timbrens. I hope they work for you. I bought a set of those, thinking they would be nice to have when I have sand bags in the rear for snowplowing. But as another poster said, when you are running unloaded, you might notice a jarring bump when you hit bumpy roads.

I actually took the timbrens off and replaced them with the OEM bumpers. Then I installed Hellwig helper springs instead. I'm happier with the ride while unloaded now.

Firestone Air Bags are the way to go. They really smoothed out the ride on my Avalanche 2500 when pulling my boat....

Nuckfan · June 10, 2016

I installed the timbrens Monday. The instal took 15 minutes to do both sides. So far I have not noticed a difference in ride, but I haven't loaded her yet. The Timbren is sitting around 1 1/2" off the axle. I'm looking forward to putting the camper on and measuring how much the rear sags, as well as the ride quality. What I like about the timbrens is they are an install and forget kind of system. There's no maintenance or any adjusting on them.

Timbrens work but they are not adjustable. I tell you when I put the air bags on my avalanche and pulled my offshore cat it was like a completely different truck

Bwoodkid · June 17, 2016

I'm sure they will help your springs out, But your truck will drop 1 1/2 until the bumps contact the axle, and those bumps will compress a bit before they start working. You may have to modify the bracket to lower them down. But it may work great also. If it still squats, take them off return and get airbags. Just ordered Air lift bags for my truck.
