HI Jesse,

Yes! The SumoSprings Solo Custom Helper Springs, part # SS46KJ, can help reduce rear end sag when towing your camper, and they’re a great option to consider if you want to replace your Timbrens without switching to air bags.

These have a 2,800 lb capacity and use progressive load control, so they compress according to the weight you’re carrying. They engage more softly with lighter loads for a more comfortable ride, then compress further under heavier loads to provide additional support. They can compress by as much as 80% to help support your factory suspension, keep your Silverado more level when towing.

What I really like about SumoSprings is that they’re maintenance-free, with no air lines or pressure to monitor, and they install without drilling. Just keep in mind that there is a 2,800 lb capacity.

What kind of camper are you towing, and how much rear sag are you seeing with your current Timbrens?
