This is a replacement Tekno 12 Tooth Straight Cut Differential Pinion Gear, to be used with the Straight Cut Ring Gear (TKR8151B).

This TKR8152B pinion gear and the TKR8151B Ring Gear (sold separately) come included with the NB48.4 as standard equipment. They can also be used optionally with older Tekno vehicles as long as the ring and pinion gears are used together.

These straight cut gears are CNC machined from high quality steel, then hardened for durability. They will provide smoother and more efficient operation than the Tekno standard gears. They also run quieter than the standard gears.

Features:

• True straight cut design for maximum efficiency
• Smoother and quieter
• CNC hardened steel construction

Note: The ring and pinion should be run as a set (TKR8151B and TKR8152B) and should not be mixed with any other gear sets.
