Precisely processed from high-strength and pressure-resistant material with stable structure against deformation and excellent sealing performance. It features resistance to high and low temperature, aging and wear. The piston movement track is accurate with sensitive and smooth air pressure conduction, enabling rapid response of high and low speed range switching without lag. Suitable for auxiliary box range gear control of ZF transmission, it maintains stable operation under heavy-load bumpy conditions without air leakage, channeling or gear disorder. With original standard size, it is compatible for installation without debugging, featuring high durability and low failure rate.
1358 334 018 Range Gear Piston
The range gear piston is adapted to the high and low speed range switching system of ZF 12-speed AMT transmission and serves as a key pneumatic control part of the auxiliary box. Precisely processed from high-strength pressure-resistant material, it has stable structure, excellent sealing performance, aging resistance, wear resistance and temperature tolerance. It features standard piston movement track and sensitive air pressure induction with no delay or gear cross in high and low gear switching. Compatible with all Sinotruk Howo heavy-duty models with ZF 12-speed transmission, it works reliably under bumpy heavy-load conditions with no debugging needed for original specification installation, low failure rate and high durability.
