Saleen Serpentine Belt 81.5" Sport Truck 2018-2021

These 6-rib 81.5" serpentine belts run quieter, stretch less, and transfer more power than other belts. As they warm up, the composite construction between the cords and rubber compound becomes more efficient at turning your engine's accessories. We recommend replacing your accessory belt as well, it is sold separately for your convenience.OEM replacement for 2018-2021 Sport Truck and fits Saleen Supercharger equipped 2018-2021 F-150 with stock Supercharger Drive Pulley.
