Radius Drive Belt - 23.6 x 1

The Radius Drive Belt - 23.6 x 1 from MOROSO is a precision synchronous belt engineered for high-performance engine accessory drive applications. Designed for builders and technicians who demand reliable power transmission in custom and competition engine builds, this belt transfers rotational force from the crankshaft to alternators, water pumps, power steering pumps, and other critical components. The 23.6-inch length suits compact engine configurations and tight underhood layouts where standard belts fall short.

This HTD (Synchronous) drive belt features an 8mm pitch tooth profile and 1-inch width, ensuring positive engagement without slippage—critical for maintaining charging system amperage and coolant circulation under sustained high RPM operation. The HTD tooth geometry distributes load evenly across multiple teeth simultaneously, reducing stress concentration and extending service life compared to conventional V-belts. MOROSO's belt construction delivers consistent performance across temperature swings and resists degradation from oil mist and heat cycling common in modified engine bays.

Engine builders, hot rodders, and LS-swap enthusiasts rely on the Radius Drive Belt for applications where factory belt lengths and profiles prove incompatible with custom pulley configurations. Installation requires HTD-compatible pulleys with matching 8mm pitch; verify existing pulley geometry before ordering. At 0.35 lbs and compact packaging dimensions, this belt integrates cleanly into space-constrained engine compartments without sacrificing drive system integrity or requiring supplementary tensioning hardware.
