Product Description

The Hellwig 1910 Pro Series Helper Spring Kit delivers up to 2,500 lbs of additional level-load capacity for 2000-2006 Toyota Tundra trucks in all cab configurations (Regular, Access, and Double Cab) and both 2WD and 4WD. Built from heat-treated ASTM 5160 alloy spring steel in a 2-leaf progressive-rate design, these Silent Support System helper springs stabilize loads, eliminate rear-end sag, and improve handling and braking when towing or hauling - all without compromising ride quality when the bed is empty.

The over-axle mounting design bolts directly on with common hand tools, and the fully adjustable U-bolts let you dial-in spring rate independently side-to-side for uneven cargo. Ideal for 1st-gen Tundra owners who regularly haul construction materials, trailer small campers, or carry heavy bed loads. Proudly made in Visalia, California and backed by Hellwig's limited lifetime warranty.
