The 1316304170 Synchronizer Ring is manufactured using high-strength chromium-alloyed steel, offering exceptional resistance to friction and thermal fatigue. Each ring undergoes precision grinding to ensure perfect conical matching with the gear cone, resulting in buttery-smooth engagement every time. This is not just a spare part; it’s an upgrade for your Howo or Sitrak transmission.
With a surface hardness of 58–63 HRC and shot-peened finish, the 1316304170 synchronizer ring handles torque spikes effortlessly. Fleet operators report a 40% reduction in gear-grinding complaints after switching to this OE-spec component — a testament to its superior friction lining and symmetrical tooth profile.
The synchronizer ring 1316304170 is engineered to operate in transmission oil up to 150°C without losing friction coefficient. Its spiral oil grooves evacuate fluid instantly, preventing hydroplaning and ensuring immediate synchronization.
With a 1.2 million shift-cycle rating (ISO 9000), this synchronizer ring outlasts standard aftermarket alternatives by 50%. It is the preferred choice for long-haul fleets and construction trucks operating in severe conditions.
Installation advantage: The synchronizer ring is a direct replacement for ZF 16S-series transmissions, including 16S150, 16S151, 16S181, 16S220, 16S221, and 16S251. Its precise dimensions eliminate the need for additional shimming, reducing workshop downtime and improving first-time fix rates.
Real-world data from fleets using this ring show a 22% increase in gearbox efficiency and a 15 dB reduction in shifting noise compared to worn or low-grade rings. This translates to driver comfort and lower maintenance costs over the vehicle’s lifecycle.
Every synchronizer ring is 100% dimensionally tested and hardness-verified before packaging. The batch traceability ensures full material certification, meeting ISO/TS 16949 standards. This level of quality control guarantees that you receive a component that performs exactly as the original equipment — no compromises.
The ring’s conical surface is ground to a tolerance of ±0.02 mm, ensuring uniform contact pressure and eliminating hotspots. This precision machining is the reason why this synchronizer ring is trusted by professional rebuilders across Europe, Asia, and the Americas.
Smooth shifting isn’t a luxury — it’s a necessity for driver safety and fuel economy. The synchronizer ring ensures that every gear change is precise, reducing the risk of missed shifts and protecting the gear teeth from unnecessary shock loads. Whether you’re climbing a steep grade or maneuvering in a crowded depot, this component delivers confidence.
Workshop professionals appreciate the plug-and-play fitment of this ring. There is no need for aftermarket modifications. Simply clean the mating cone, lubricate with transmission fluid, and install. The ring’s anti-rotation tabs lock securely into the hub, preventing disengagement during high-speed operation.
In combination with high-quality transmission oil, this synchronizer ring can achieve over 800,000 km of service life in on-highway applications. For off-highway and mining operations, the robust construction still delivers more than 500,000 km of reliable performance — a clear return on investment.
In summary, the Synchronizer Ring is the ultimate choice for maintaining and upgrading your Howo, Sitrak, or ZF-based transmission. Its material science, precision engineering, and proven durability make it a cornerstone of drivetrain reliability. Choose the ring that keeps your trucks moving — choose 1316304170.
