Tired of dealing with belt tensioners that fail around 50K miles? The factory belt tensioner for the 2017-2024  L5P Duramax is notorious for its plastic pulley that wears down and breaks, leaving your truck stranded.

With our Billet Aluminum Pulley, you get unmatched reliability and peace of mind, keeping your Duramax running strong when it matters most.
