Firestone Ride-Rite RED Label Extreme Duty Rear Air Spring Kit - 2012-2025 Chevrolet Silverado / GMC Sierra 3500HD Cab & Chassis

When a Chevrolet Silverado / GMC Sierra 3500HD Cab & Chassis spends its life loaded, RED Label is the Firestone kit to run. The air springs bolt in between the frame and rear axle of the 2012-2025 Chevrolet Silverado / GMC Sierra 3500HD Cab & Chassis and add support you control with air pressure. Inflate before you load and the rear stops squatting, so the front end keeps the weight it needs to steer and stop, and your low beams stay on the pavement instead of the treetops. Bleed them back down when the bed is empty and the ride goes back to about where the factory had it. Cab and chassis trucks like the Chevrolet Silverado / GMC Sierra 3500HD Cab & Chassis often wear service bodies or flatbeds that load unevenly.

This is Firestone's commercial line: heavier rubber, coated brackets and a build meant for trucks that pull fifth-wheels and goosenecks or carry service bodies and campers every week. Load leveling is rated at up to 7,500 lbs, the springs handle up to 150 PSI, and the truck's GVWR remains the limit.

Features

• Keeps the rear from squatting under tongue weight or a loaded bed
• Spring pressure range: 5 PSI minimum to 150 PSI maximum
• Run different pressures per side for lopsided cargo
• Frame-to-axle mounting with vehicle-specific brackets
• Air pressure sets the support level for whatever you are carrying
• Less sway and better control with weight in the bed or on the hitch
• Rated for 7,500 lbs of leveling support; stay under GVWR
