Developed for heavy-duty class 8 trucks with DD13, DD15 and DD16 series engines, these kits include Dayco’s 2-piece tensioner, two premium pulleys and two serpentine belts. Because of the unique features of the tensioner, the kits streamline the repair process, ensuring all components needed for an optimum performing belt drive system are replaced together, extending the time between service intervals.
Engineered from OE-equivalent parts:
- 2-piece tensioner and pulleys machined from high-strength steel provide excellent wear resistance in extreme environmental conditions
- EPDM belts with specially treated cords reduce rib cracking, provide increased flexibility and run cooler
