3RACING Cero Titanium Spur Gear Locker SAK-C118A Racing Upgrade  [SAK-C118A]

Technical Spur Lock Solution for Cero

The 3RACING Cero Titanium Spur Gear Locker SAK-C118A is engineered to minimize axial and rotational play between the spur and shaft. Intended for competitive use, the part focuses on repeatable engagement and stable torque transfer under varying loads.

Material and Mechanical Benefits

CNC grade titanium offers a high strength to mass ratio and excellent fatigue resistance, reducing the risk of loosening during heat cycles. The precise fit reduces micro movement that can lead to inconsistent timing and drivetrain losses.

Fitment Notes and Tuning

Designed around Cero dimensional standards, installation follows standard spur removal and replacement methods. Check pinion engagement and use standard shimming procedures. The locker supports both track tuning and higher power motor setups when combined with correct gear ratios and lubrication practices.
