Gilmer Belt 23.25in Long 1in Wide

The Gilmer Belt 23.25in Long 1in Wide from Jones Racing Products is a precision serpentine drive belt engineered for high-performance automotive applications, custom engine builds, and race-oriented vehicle modifications. This belt is purpose-built for enthusiasts and mechanics who demand reliability in demanding engine bay environments where OEM serpentine belts fall short. Whether you're upgrading a modified naturally aspirated engine, installing a supercharger or turbocharger system, or constructing a custom engine package, this Gilmer-style belt provides the durability and grip required for consistent accessory drive performance.

Featuring a 3/8 inch pitch tooth profile, the Gilmer Belt 23.25in Long 1in Wide offers superior load-carrying capacity and reduced slip compared to traditional V-belts, making it ideal for high-RPM applications and systems with elevated alternator and water pump demands. The 1-inch width provides a broad contact surface for optimized power transmission, while the 23.25-inch length accommodates a range of compact and mid-sized engine configurations. Jones Racing Products manufactures this belt to exacting tolerances, ensuring consistent tooth engagement and minimal deflection during sustained operation. The lightweight construction (0.12 lbs) minimizes rotational inertia, preserving parasitic horsepower while maintaining absolute reliability under boost or high-revving conditions.

This Gilmer belt is ideal for custom engine builders, performance shops, and serious weekend warriors who are assembling tight-clearance or non-traditional engine configurations where standard serpentine systems won't fit or perform adequately. It pairs seamlessly with custom accessory drive kits, crate engines, and billet pulley systems common in street rods, race cars, and heavily modified production vehicles. Installation requires compatible Gilmer-profile pulleys (verify your alternator, water pump, and power steering pump pulley sizing before purchase) and proper tensioning to maximize belt life and accessory drive reliability. Check your engine's documentation or consult with your builder to confirm the 23.25-inch length and 1-inch width suit your specific accessory configuration.
