This ZF 1372 304 016 main shaft adjustment shim is compatible with 12AS series 12-speed AMT transmissions.
Precision stamped from high-quality high-carbon steel, it features uniform thickness, high flatness, and strong resistance to deformation and warping.
Subjected to quenching and anti-rust treatment, it resists transmission oil corrosion, compression and wear, and avoids rusting and aging.
Manufactured strictly to OEM dimensions, it precisely controls the main shaft axial clearance and meshing accuracy, balances gear transmission backlash, and reduces operating vibration and shifting abnormal noise.
With excellent material toughness and stable dimension under pressure, it maintains reliable performance under long-term heavy-duty operation. Easy to install, it is an essential precision part for transmission clearance adjustment and maintenance.
