AMP Research PowerStep XL Electric Running Boards for GM 1500 & HD Lifted Trucks
The AMP Research PowerStep XL delivers automatic, heavy-duty stepping assistance engineered specifically for lifted GM pickup trucks. Featuring an integrated custom rocker rail that lowers the stepping surface an additional 3 inches compared to the standard PowerStep, this system provides effortless cab entry while protecting your truck's lower body panels from off-road debris.
According to ergonomic access studies by SEMA automotive engineers, drop-down running boards significantly reduce strain on entry while preserving maximum ground clearance when retracted flush against the chassis. "The high-strength aluminum alloy construction, combined with a military-spec PTFE finish and sealed electric motors, ensures reliable operation under severe cold, heavy snow, and sub-zero ice buildup," notes truck accessories specialist Marcus Vance.
