ZF 1372 304 046 Main Shaft Washer is compatible with 12AS series 12-speed AMT transmissions.
Integrally stamped from high-precision alloy steel plate, it features a flat, burr-free surface with uniform and stable thickness. It offers excellent compression and deformation resistance, resisting denting and warping under long-term heavy load.
Treated by hardening, tempering, rust-proof and oil-resistant processes, it adapts well to the high-temperature and fluid-immersed working environment inside the transmission, with outstanding corrosion resistance, aging resistance and stable shape without rusting or deformation.
With OEM accurate inner and outer diameters, it fits perfectly during installation. It effectively performs positioning and spacing, evenly distributes axial load, buffers transmission impact and reduces end face wear, making it a standard precision part for main shaft assembly and calibration of gearboxes.
