Material & Advantages

1. Integral forged alloy steel blank with full carburizing quenching, high lock tooth surface hardness, anti-impact and anti-fatigue under frequent high-load shifting

2. Precision CNC ground lock teeth and inner splines, smooth meshing without jamming, uniform stress distribution to avoid partial tooth abrasion and breakage

3. Strict OEM outer diameter, tooth profile and inner spline dimension, perfect fit original synchronizer sleeve and main shaft without cutting or polishing modification during overhaul

4. Hollow lightening hole design reduces plate weight, improves lubricating oil circulation inside synchronizer assembly to avoid dry grinding

5. Optimized tooth root transition arc lowers stress concentration, effectively prevent lock tooth collapse under long-distance mountain heavy haul conditions

6. Standard locking clearance eliminates gear jumping and shifting vibration noise, extend service life of matched synchro ring and sliding sleeve
