Suffering from rear-end sag and sway is always a possibility when your GM Sierra/Silverado is loaded down, even if you haven't reached the your truck's GVWR or GCWR.

Luckily for you, the fix is made is easy with the SuperSprings 1500lb Rear SumoSprings as they were specifically engineered to improve the overall cargo-carrying capabilities of your ride. These high-quality helper springs work by holding up to 1500lb pounds of the load at just 50% compression, eliminating any of the unattractive sag when you're towing a heavy trailer. Additionally, the load-carrying capabilities of these SumoSprings allow for full memory rebound at 65% compression and are designed to never leak or rupture. The impressive durability that comes with these springs is thanks to the patented micro-cellular polyurethane construction, providing a smooth and progressive spring rate without the requirement of airlines or compressors.

Premium Construction & Simple Installation

SuperSprings designed their premium 1500lb Rear SumoSprings using only premium materials and most advanced design processes to ensure a perfect fit and fucntion on your tough GM Truck. The patented micro-cellular polyurethane construction adds a ton of durability to your truck's suspension system, giving you an extra boost of confidence for those tough jobs. The springs work by pushing up against the main spring to keep it located on it's upper and lower perch. When the damper compresses, the SumoSpring becomes a solid base for the main spring to operate upon, all without affecting the main spring rate at all. When it comes to installation, these helper springs replace the OEM bump-stop on your rig using a simple, bolt-on process you can complete right in your garage. SuperSprings includes all of the necessary hardware and instructions required for installation, and offers a Limited Lifetime Warranty to help keep your investment protected.
