The FR1200S center differential kit is an aftermarket RC-scale replacement for TRAXXAS 1/10 4WD platforms listed below. It upgrades the factory limited-slip centre differential to a more durable unit that combines a 7075 aluminum housing with medium carbon steel output gears to better cope with higher power inputs.
The assembly balances torque across all four wheels while reducing reverse driveline stress on the transmission shaft. Delivered as a centre differential kit, it contains the internal components shown in the original part list and requires user-supplied differential silicone oil to set the desired lock and torque split characteristics.

Recommended for modellers who want a stronger, serviceable centre differential to replace the factory limited-slip unit. Continue to use differential silicone oil to fine tune lock and torque split, and pair the included 54T medium carbon steel spur with a suitable 32P pinion where needed.
