Product Features

• High-Precision Synchronization: Engineered with exact tooth profiles to ensure rapid speed matching between the shaft and gears, eliminating "gear grinding" during shifts.
• Superior Material Strength: The hub and sleeve are forged from 20CrMnTi alloy steel with specialized heat treatment for maximum torque resistance and impact toughness.
• Optimized Shift Comfort: Designed to reduce the physical force required by the driver to engage 3rd and 4th gears, leading to less driver fatigue.
• Thermal Stability: Capable of maintaining consistent friction coefficients even under high-temperature environments caused by long-distance, high-load transport.

Precautions for Use

• Avoid "Gear Grinding": If you hear grinding when shifting to 3rd or 4th, the synchronizer friction lining is likely worn; replace immediately to avoid damaging the main gears.
• Installation Direction: The hub and sleeve have specific orientations. Installing them backwards will cause shifting failure or gear lock-up.
• Cleanliness: Ensure the gearbox interior is flushed of metal shavings before installing a new synchronizer to prevent premature wear.
