This adjusting gasket is elaborately made of high-quality alloy steel and undergoes precise quenching and tempering treatment, delivering uniform overall hardness, excellent toughness, and strong compression resistance against deformation.

Exquisitely cut and polished with high dimensional accuracy and good flatness, it features strictly controlled tolerances and is ideal for clearance calibration and assembly inside gearboxes.

With outstanding wear and corrosion resistance, it withstands long-term heavy-duty operation as well as high and low temperature working conditions. It effectively optimizes gear meshing clearance, reduces gear shifting abnormal noise and jamming, stabilizes the transmission structure, and extends the overall service life of the gearbox. It is compatible with all mainstream gearbox models of Sinotruk.
