Great âset it and forget itâ suspension upgrade
This is a great âset and forget itâ option for people who carry heavy loads or tow. Putting this on my three-quarter ton Chevy stopped the bouncing that I was getting from my travel trailer with over 1200 pounds of tongue weight.Empty ride has not degraded at all. I found this option pretty easy to put on simple water and more cold brew than airbags.

Fit good
Bought these to replace tembren suspension on rear of chinook van. Tembren didnât work well at all.Pretty easy to install but a little difficult to adjust. Must have suspension hanging and itâs a little bit easier. I didnât and it took. Lot of effort to adjust to lightest setting. Once installed they drastically improve side to side sway and have little effect on ride quality

DD best ride ever
I took my Timbers off and put on RDS 2500 HD with 14,000 lb. Camper and they work so good. Very smooth over bridges. Also rides better with no load.ð

The easy installation!
The RAS system has improved the handling of my truck both with my 5th wheel trailer and without the trailer and the ease to install it was very good! Would recommend to anyone with a truck or a truck and trailer!!

Great alternative to airbags
The mechanical advantage of being without airbags, pumps etc. Helps my 2010 Silverado 2500 hd handle better loaded & empty.

Easy install, improves ride
Very easy install. Takes longer to raise the truck and remove the tires than to install the suspension system. They improve the ride both towing and not towing. Also helped with sag when towing my 5th wheel.

Works great on my 2024 Nissan Titan XD
I have a 2022 Forest River Work and Play 21LT toy hauler that has a hitch weight of 935 lbs and without a weight distro I was sagging. My truck is a 2024 Nissan Titan XD with Class IV hitch. After installation of the RAS and setting it with the black shim this was my result. I’m very happy and would recommend it.
