Description
A Tundra CrewMax has a tall cab entry, especially when the truck sits on larger tires. The AMP 77338-01A PowerStep XL drops its running boards farther from the rocker than the standard PowerStep arrangement, providing an additional step down when doors open.
The powered XL system retracts against the truck when not needed. AMP’s installation instructions show the bracket and harness locations for the 2022-generation Toyota Tundra CrewMax. This specific part is not a universal Tundra Double Cab or earlier-generation step package.
