Enhanced Suspension Performance and Control

Suffering from sag and rear sway is a always a possibility when your Sierra/Silverado is loaded down, even if you haven't quite reached the manufacturer's GVWR or GCWR. While many times your GM truck is more than capable of holding its own, rear sag and sway can cause a number of problems when you're out and about. Luckily for you, the solution is made simple with the SuperSprings 1500lb Rear SumoSprings as they were specifically engineered to improve the overall control and comfort of your ride by holding up to 1500 pounds of the load at 50% compression. Additionally, the enhanced load-carrying capabilities of these SumoSprings allow for full memory rebound up to 65% compression and are designed to never leak or rupture. The durability of the SumoSprings come from the patented micro-cellular urethane construction, which provides 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 design processes to ensure a perfect fit, form, and function on your 2011-2023 GM 6.6L Duramax. Made from patented micro-cellular urethane, these springs work by pushing up against the main spring to keep located on it's upper and lower perch. When the damper compresses, the SumoSpring fully compresses and 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, the SumoSpring replaces the OEM bump-stop using a simple, bolt-on process that you can complete at home. SuperSprings includes all the necessary instructions and hardware required for installation and offers a Limited Lifetime Warranty to help keep your investment protected. SuperSprings are proudly made in the USA.
