Fits select 1997-2007 Chevrolet Silverado 1500, GMC Sierra 1500, and Ford F-150/F-250 models.

The Firestone Sport-Rite Rear Air Helper Spring Kit is engineered to provide a balanced solution for drivers who demand both ride comfort and heavy-duty load support. These tapered air springs mount between the vehicle frame and the rear suspension, delivering a progressive spring rate that improves ride quality when empty while providing up to 3,000 lbs. of load-carrying capacity per set when hauling. By reinforcing your vehicle's factory suspension, this kit effectively maintains a level stance, reduces suspension fatigue, and prevents bottoming out during heavy towing or transport.

Beyond weight support, the Sport-Rite system enhances overall vehicle stability and control. Independent air adjustment allows you to level off-center loads, ensuring your truck remains predictable and safe on the road. Built for durability and precise fitment, this kit replaces or assists worn OE components to restore and improve handling performance.
