If you're making over 400whp, you'll want these upgraded pulleys to keep your serpentine belt intact! The Mitsubishi OEM pulleys are made from plastic and will permanently distort with big power, causing your belt to walk and shred time and time again. Don't leave yourself stranded and constantly in need of a new belt. Fix the problem by installing these steel pulleys.
Note: The pulley that goes onto the OEM belt tensioner will require the use of the provided washers to ensure proper the clearance for the pulley to fit.
