Differential Ring Gear (CNC 39t Use with Tkr8152b)

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 ring gear and the 12t pinion gear (TKR8152B) are standard with the NB48.4 vehicle.

Overdrive
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.
