For 1st Gen Tundra owners dealing with advanced frame corrosion from winter salt and de- icers, our Weld-In Reinforcement Plate (set of two, 11-gauge) offers an affordable, effective repair solution. It serves as a "fish plate" to bridge and reinforce damaged sections of the frame rail (especially the original reinforcement channel just forward of the rear tire), welding in place to restore basic structural strength. While it doesn't fully replicate the original cha

First-generation Toyota Tundras (2000-2006), especially Double Cab models, are built tough—but decades of exposure to winter road salt, anti-freeze agents, and de-icing chemicals accelerate frame corrosion, particularly in the rear sections. The original Toyota reinforcement channel just in front of the rear tire is a common failure point: rust eats away at it, compromising structural integrity, reducing tow capacity, and creating safety risks. Our 1st Gen Tundra Double Cab B

Access Cab versions of the 1st Gen Tundra face the same salt-induced corrosion challenges as Double Cabs, with the original reinforcement channel ahead of the rear tire particularly vulnerable to rust perforation from road salt and anti-freeze runoff. Weakened frames here can lead to sagging, handling issues, and reduced confidence in towing or hauling. Our 1st Gen Tundra Access Cab Bolt-In Frame Support Channel mirrors Toyota's original design, bolting directly into the
