Belt Serpentine 33.465in 6-Groove

The Belt Serpentine 33.465in 6-Groove from Jones Racing Products is a high-performance serpentine belt engineered for vehicles demanding reliable accessory drive power in demanding conditions. This 33.46-inch, 6-rib belt is the go-to choice for modified and performance-built engines where factory serpentine belts fall short. Whether you're running an upgraded alternator, high-output water pump, or custom engine bay setup, this belt delivers consistent engagement across all accessory pulleys without slipping or degradation under sustained load.

The 6-groove design maximizes contact surface area between the belt and pulleys, reducing slip and improving power transmission efficiency compared to standard serpentine belts. The HD (heavy-duty) construction utilizes premium elastomer compounds and reinforced synthetic fibers that resist heat cracking, fraying, and premature wear—critical factors when running high-amp alternators or supercharger systems that generate sustained friction and thermal stress. At just 0.19 lbs, the belt maintains minimal rotational inertia while delivering the durability required for long-term track use, street performance applications, or extreme duty cycles that would wear out OEM belts rapidly.

Technicians and engine builders choose Jones Racing Products serpentine belts when OEM units cannot meet the demands of upgraded accessory systems or high-RPM applications. Installation requires verifying pulley alignment and tension settings specific to your vehicle platform—improper tension leads to slipping or accelerated wear, so consult your engine's specifications or shop manual during fitment. This 6-groove serpentine belt is essential for anyone upgrading charging systems, cooling capacity, or building a street or competition engine where reliability and consistent accessory drive performance cannot be compromised.
