This kit fit my 2012 Sprinter 3500 perfectly at a price that cannot be beat. When I pulled the original parts off of the engine, I noted that the INA brand replacement part for both idler pulleys had the EXACT same bearing as the original OEM part installed at the factory. These are parts I can trust and technical advice I can trust rather than some unknown part put into a box with some national auto parts store branding. When I priced the parts listed at one of national chain stores that rhymes with "own", the total cost would have been about $240 for similar parts (Continental for belt and tensioner, unknown brand for the idler pulleys). If you buy these parts at the "Oh" shamrock stores, that'll be $309. And at the chain with the checkered flag, hang on to your wallet because their parts will set you back almost $400 !! And you won't find the kind of knowledgeable staff behind the counter like you can with the people who only do diesels at idparts. Thank you for getting me the exact parts I needed in one easy kit.

excellent parts and fast shipping
