This ZF 0501 328 496 mainshaft snap ring is compatible with 12AS series 12-speed AMT transmissions.

Precision manufactured from high-wear alloy material, it features high overall toughness, resistance to deformation and cracking, as well as outstanding high and low temperature resistance and anti-aging performance.

Its inner and outer diameters and groove dimensions strictly comply with OEM standards. It slides smoothly without jamming when matched with sliding sleeves and spline sleeves, ensuring accurate gear shifting travel.

With precision polishing and hardening surface treatment, it has a low friction coefficient and long wear-resistant service life. It is not prone to looseness or failure under heavy-load and frequent shifting conditions. Featuring high installation compatibility, it is an ideal original replacement part for the maintenance of transmission shifting mechanisms.
