The Cognito Comfort Ride leaf springs for 2011–2024 Chevy/GMC Silverado and Sierra 2500/3500 HD increase compression travel before the bottom overload activates to improve ride quality. Supplied as complete direct-replacement leaf packs, they deliver a measured improvement in ride comfort but will reduce load-carrying capacity by about 22% on 2500 trucks; helper airbags are recommended when towing heavy loads. Made in the USA and sold as a pair.
