If your belt slips, you lose boost, and if the tensioner fails, you risk belt failure. The BDS Idler Pulley Assembly is built to handle the high-torque demands of forced induction, providing the strength and stability required to keep your blower spinning at the correct speed. Its polished aluminum construction not only looks great but also helps dissipate heat, further extending the life of your drive belt.
