This is an optional Tekno RC Straight Cut Differential Ring Gear. This gear is CNC machined from high quality steel, then hardened for durability. The straight cut gear will provide smoother, quieter and more efficient operation than the standard Tekno ring gear. The ring gear must be combined with the straight cut pinion gear (TKR5152) and should not be mixed with TKR5110 or TKR5111.

Features:

• True straight cut design for maximum efficiency
• Smoother and quieter than our standard gears
• CNC hardened steel construction
