130 Tooth 1 1 8" Rear Drive Belt For HARLEY & CUSTOM CHOPPERS REPL 40048-07

Description:

The Harley-Davidson 130 Tooth 1-1/8" Rear Drive Belt (replacement for OEM 40048-07) is used in motorcycle final drive systems to transfer engine torque from the transmission pulley to the rear wheel pulley. It is a reinforced aramid-cord rubber drive belt designed for high tensile strength, heat resistance, and consistent power delivery in heavy-duty motorcycle applications. Commonly installed in Harley-Davidson Dyna and custom chopper builds requiring OEM-spec belt replacement where original belts are worn, cracked, or stretched. Motorcycle repair shops, custom builders, and service technicians use this part for drivetrain restoration, maintenance, and final drive replacement.

Applications:

The 130T 1-1/8" Harley rear drive belt is used in motorcycle final drive systems to transmit engine power to the rear wheel with smooth, low-noise operation and reduced maintenance compared to chain systems. It is commonly applied in Harley-Davidson Dyna FXD/FXDWG models (2007–2017) and compatible custom chopper builds using the 40048-07 belt specification.
