RETRUE 5,000 LBS Heavy-Duty Air Suspension Kit for 2007-2021 Toyota Tundra - No-Drill Rear Air Helper Springs - Load Leveling Towing Kit (Compatible with Firestone Ride-Rite 2445 Replacement)

[5,000 LBS HEAVY-DUTY LEVELING] Stop dangerous rear-end sag when towing heavy trailers, boats, or horse trailers. Our air helper springs provide up to 5,000 lbs of load-leveling capacity, ensuring your Tundra maintains a level stance for optimal traction, headlight aim, and front-wheel steering control.

[THE PROFESSIONAL 2445 ALTERNATIVE] Specifically designed as a high-performance alternative to the Firestone Ride-Rite 2445 kit. Experience the same precision fitment and engineering reliability for your 2007–2021 Tundra with RETRUE’s enhanced durability.

[TRUE NO-DRILL, BOLT-ON INSTALL] Protect your truck’s frame and maintain its resale value. Our kit features a 100% bolt-on design with precision-cut, pre-drilled brackets. No drilling or permanent frame modifications are required—install it in your driveway in a few hours with standard hand tools.

[5-100 PSI FULL ADJUSTABILITY] Take total command of your ride quality. Adjust air pressure to 5 PSI for a factory-smooth ride when empty, or firm it up to 100 PSI to stabilize heavy payloads, reduce body roll, and eliminate "bottoming out" on rough roads.

[COMMERCIAL-GRADE STRENGTH] Built for the American job site. Constructed with reinforced high-density rubber bellows and corrosion-resistant hardware, this kit is designed to handle harsh road salt, mud, and extreme weather without leaking or cracking.
