ZF Genuine 1372 304 043 Main Shaft Washer is compatible with 12AS series 12-speed AMT transmissions.
Precision stamped and finely processed from high-quality alloy steel plate, it has a flat, smooth surface and uniform thickness. It features high pressure resistance and is not easy to dent, warp or deform under heavy-load impact.
With hardening and anti-rust treatment, it resists gear oil corrosion, high temperature and oxidation, and avoids rust and failure during long-term high-speed operation.
Adopting OEM standard inner bore and outer diameter, it fits closely after installation. It effectively performs limiting and spacing, shares axial load, and reduces end-face friction between the main shaft and gears.
Exquisitely crafted with high durability, it is a standard dedicated part for transmission maintenance and calibration.
