Synchronizer Sleeve 1310304202 ZF

The Synchronizer Sleeve 1310304202 ZF is a precision-engineered transmission component designed to ensure smooth, reliable gear engagement in manual gearboxes used across heavy-duty trucks, buses, and commercial vehicles. This part plays a critical role in the synchronization process by enabling controlled coupling between the synchronizer hub and the selected gear, allowing seamless speed matching and reducing shock during gear shifts. Manufactured to OEM-level dimensional accuracy, this synchronizer sleeve is fully interchangeable with genuine spare parts and meets the mechanical and metallurgical standards required for demanding drivetrain applications. The internal tooth profile is precisely machined to ensure correct engagement geometry, minimizing wear on mating components and maintaining consistent shift quality over long service intervals. Built from high-strength, heat-treated alloy steel, the sleeve offers excellent resistance to torsional stress, surface fatigue, and repeated load cycles typical in heavy commercial vehicle operation. Its hardened surface finish improves durability under high torque and frequent shifting conditions, helping extend the service life of the synchronizer assembly and gearbox as a whole. This component is widely used in transmissions compatible with leading commercial vehicle brands, including IVECO, DAF, Mercedes-Benz, MAN, Renault, Volvo, ZF, Astra, Isuzu, Hino, and Pegaso. This broad compatibility makes it an ideal solution for fleet maintenance, gearbox overhauls, and professional transmission rebuilds.
