Open F/R Diff Set GP4 5mm 10K (ARA311066)

Open Front or Rear Spiral-Cut Differential Set for ARRMA vehicles. This pre-assembled unit is designed for front- or rear-installation and arrives pre-filled with 10,000 cSt silicone oil for quick servicing. It includes a 43-tooth GP4 spiral-cut main gear and a 29mm differential case to provide reliable open-differential action.

Constructed with tough steel internal gears and a durable composite diff case with an integrated steel insert, the set is built for long-lasting performance under demanding conditions. It features metal cross shafts for efficient power transfer and rubber shielded bearings for smooth installation. Open-differential action is favored on the rear axle, and spare 29mm diff-case parts are available for maintenance.
