NAPA serpentine kits are a win-win: They offer peace of mind and cost savings to fleet managers and auto repair consumers.
The peace of mind comes with the lifetime parts and labor warranty. The cost savings comes in being able to easily combine separate repair jobs into one.
NAPA did a cost comparison on a 2012 Toyota Camry and determined it was $160 more to replace the alternator, belt and tensioner separately vs. using a NAPA serpentine kit.
Each kit is tailored for the vehicle and comes with the necessary NAPA serpentine belt(s), belt tensioner(s) and idler pulley(s).
