Gilmer Belt 22.5

The Gilmer Belt 22.5 is a serpentine drive belt engineered for high-performance engine accessory drive systems in racing and performance automotive applications. Manufactured by ALLSTAR PERFORMANCE, this belt is designed for users who demand reliable power transmission from their engine's crankshaft to alternators, water pumps, and other driven components. The Gilmer tooth profile delivers superior grip and efficiency compared to traditional V-belts, making it essential for serious racers and performance enthusiasts who cannot tolerate slippage under demanding conditions.

This 22.5-inch Gilmer belt features a 1-inch width and 3/8-inch pitch tooth profile, specifications that enable precise load distribution and minimal stretch during operation. The toothed design eliminates the creep associated with flat or V-belt systems, ensuring consistent belt speed and pulley synchronization even under sustained high RPM loads. The belt's compact 0.17-pound weight and manageable 9.1-inch overall length make installation and routing straightforward, while the Gilmer tooth geometry is optimized to prevent tooth jump and maximize power transfer efficiency in tightly configured engine bays.

Racers, engine builders, and performance shops favor the Gilmer Belt 22.5 for custom serpentine belt systems on small-block and mid-sized engines requiring precise accessory drive synchronization. The 22.5-inch length suits compact engine configurations and street rods where space is limited and reliability is non-negotiable. Installation requires compatible Gilmer-profile pulleys; verify your crankshaft, alternator, and auxiliary component pulleys are equipped with matching tooth profiles before purchase to ensure proper fit and performance.
