Technical Performance

This superior oil seal transfer case is precision-engineered for high-torque drivetrains, effectively blocking external contaminants while retaining critical gear lubricants.
Crafted from high-performance elastomers, this component serves as a reliable rear output shaft seal transfer case, maintaining excellent resiliency under harsh off-road conditions.
Its unique lip geometry actively compensates for rotational runout, significantly enhancing the transfer case oil seal resistance to seepage at elevated temperatures.
Acting as a high-precision front output shaft seal, it maintains constant contact pressure during high-speed rotation, preventing fluid leakage caused by pressure fluctuations.
Whether under extreme operational loads or drastic thermal shifts, this sealing assembly operates steadily, providing long-lasting protection for your entire drivetrain system.
Manufacturing & Quality Control
We utilize advanced precision-molding technology to produce each transfer case input seal, ensuring strict adherence to industrial tolerances and assembly requirements.
