Suitable for hydraulic retarders of ZF 12-speed AMT gearboxes, featuring integrated molding design with solid structure that resists strong oil pressure impact and avoids cracking damage. Precisely milled sealing grooves fit standard sealing parts perfectly for superior airtightness to maintain stable oil pressure output. Designed specially for mountainous heavy-load working conditions, it delivers stable and balanced braking torque with low idling resistance to save fuel consumption. It is highly practical and compatible with most mainstream heavy-duty truck models.
6093201020 Retarder Piston
Suitable for hydraulic retarders of ZF 12-speed AMT gearboxes, the integrally formed piston features strong compression resistance to withstand intense oil pressure without deformation. The precisely processed grooves fit sealing parts perfectly to maintain stable internal working oil pressure. Developed for mountainous heavy-load roads, it outputs steady braking torque and reduces driving energy consumption. With wide universal specifications, it achieves stable vehicle installation and high cost performance.
