Gilmer Drive Belt - 25.5 x 1

The Gilmer Drive Belt - 25.5 x 1 from MOROSO is a precision synchronous belt designed for high-performance engine accessory drives and serpentine applications. This belt is ideal for builders and mechanics looking to upgrade to aftermarket alternators, water pumps, power steering pumps, or custom belt routing configurations where standard serpentine belts may not suffice.

Featuring a synchronous Gilmer design, this belt has positive teeth that grip corresponding pulley grooves, effectively eliminating slippage that can occur with flat belts under high-load conditions. The 25.5-inch length and 1-inch width provide a precise fit for compact engine bay layouts or specialized pulley configurations commonly found in street rods, drag vehicles, and engine conversion projects. The belt material is engineered to resist heat degradation and maintain tension stability, making it a superior choice for performance applications.

This belt is particularly beneficial for builders working with custom accessory arrangements, ensuring reliable power transmission without premature wear. It is essential to verify your existing Gilmer pulley set before purchase, as the tooth profile and spacing must match your components for proper engagement. Installation requires careful attention to detail to ensure optimal performance.
