Product Description

TKR8152B – Diff Pinion (12t, CNC, use with TKR8151B)

These gears are CNC machined from high-quality steel, then hardened for durability.  They will provide smoother and more efficient operation than our standard gears.  They also run quieter than the standard gears.  The ring and pinion should be run as a set (TKR8151B and TKR8152B) and should not be mixed with any other gear sets.

This diff pinion and the 40t diff ring gear (TKR8151B) are standard on the NB48.4 vehicle.


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


There are performance advantages when overdriving the front of a vehicle, especially with loose track conditions. Since the front tires will be driven slightly faster, the front tires will pull the vehicle and the rear will push less.  This can generate more on power traction on low-grip tracks, resulting in additional corner speed and increased rear traction.  Overdrive is typically not recommended for medium to high grip tracks.

Please reference the following chart to utilize overdrive on variants of the EB48, NB48, SCT410, ET48, NT48 EB48SL and MT410 vehicles.
