FR1200S Center Differential Kit 7075 Housing Medium Carbon Steel Gears FR1200S by GPM  [FR1200S]

Precision centre differential for 1/10 4WD upgrade

The FR1200S center differential kit is an aftermarket RC-scale replacement for TRAXXAS 1/10 4WD platforms listed below. This upgrade replaces the factory limited-slip centre diff with a stronger assembly featuring a 7075 aluminum differential housing and medium carbon steel output gears to raise drivetrain durability under 3S LiPo load.

The assembly routes torque to all four wheels while reducing reverse driveline stress on the transmission shaft. Supplied as a serviceable center differential kit, it includes the internal parts referenced in the original part list and requires the user to add differential silicone oil to tune lock and torque split characteristics.

Intended for hobbyists seeking a serviceable, higher strength centre differential to replace the factory limited-slip unit. Use differential silicone oil to set lock and torque split, and match the supplied 54T medium carbon steel spur with the correct 32P pinion as required for your drivetrain.
