This is an optional XRAY X12 1/12 Pan Car Gear Differential Set. XRAY self-designed, revolutionary, super-smooth gear diff for 1/12 pan cars is a direct replacement for the ball-differential; it is a complete set which requires no other extra parts and no extra adjustments.
Using the gear differential makes the car more stable and easier to drive, especially in high-traction conditions. The gear diff increases on-power steering which is needed on almost all types of tracks. A “must have” for every racer.
The complete gear differential set includes a composite case and cover, precision-molded internal satellite gears made from special XRAY-developed composite material, all ensuring long lifespan and super-smooth efficient operation. A super-strong hollow steel shaft ensures maximum reliability and strength.
The advantage of the gear diff is that it is maintenance-free. When the diff is correctly built, there is no need for maintenance for a very long time, no need for frequent oil changes, and no leakage due to a superior sealing system.
