Product Advantages
This 3290142X serpentine belt is specifically designed for 4BT, 6.7L, and 8.3L diesel engines. It perfectly matches the power transmission system of Cummins engines and is suitable for heavy-duty equipment such as commercial vehicles and construction machinery. The toothed molding process ensures precise meshing with the engine pulley, achieving a transmission efficiency of ≥98% and providing low noise and high wear resistance. Oil-proof and anti-static treatments give it an IP54 protection rating, effectively preventing oil and dust intrusion and making it suitable for harsh working conditions such as sandstorms.
