Included in this kit are 3 of our 90mm idlers, which are a direct replacement for the factory 90mm idlers. When using this kit you replace the factory stamped steel idlers with robust billet aluminum idlers that aren't prone to cracking/exploding like the factory idlers are. When replacing the factory 90mm idlers with our 90mm idlers there is no change in necessary belt length.
