XRAY 304901 X4 Gear Differential Set - Precision Diff Upgrade  [XR-304901]

Precision Differential Solution for the X4

The XRAY 304901 X4 Gear Differential Set is engineered to refine traction and drivetrain behaviour on the X4 platform. The set includes a durable composite diff case and cover plus the pulley to ensure neat installation. Precision-moulded composite gears are matched with low-mass, hard-coated aluminum outdrives to reduce internal resistance and deliver more linear power transfer.

Bleeding Ports and Rear Belt Stability

The diff case incorporates bleeding ports for the M2.5x8mm screws which reduce the risk of stripping during tightening and allow surplus oil to be released without harming the seal. The adjusted case profile also recentres the rear belt, yielding steadier tracking and improved forward traction.

Reliable Sealing for Fewer Services

With correct assembly, this XRAY X4 Gear Differential requires little maintenance thanks to an effective sealing approach that keeps lubricant contained. That reliability helps maintain consistent lap times across events.

Optimised for Carpet and Tarmac

Geared for both carpet and tarmac surfaces, the differential boosts on-power steering and overall balance, making it a sound upgrade for racers chasing consistent handling.
