6831155 housingassy-piston Allison spare parts

The Allison 6831155 housingassy-piston is a core component of the Allison automatic transmission clutch control system. It is mainly used for piston mounting, oil circuit sealing, and pressure transmission to ensure stable and reliable clutch engagement and disengagement. It is widely compatible with Allison heavy-duty transmissions and is a key replacement assembly for repairing clutch pressure relief, slippage, shift shock, and other faults.
This product is precision cast from high-strength alloy material, with a high degree of inner wall smoothness and strict dimensional tolerances. Combined with the original factory-grade sealing structure, it will not deform or leak pressure under continuous high pressure and high temperature oil conditions, effectively transmitting hydraulic pressure and ensuring smooth clutch engagement and lossless power transmission.
