Upgrade your setup with the XRAY X4 Composite Gear Differential Case, featuring a 38T pulley and strong composite construction for steady drivetrain response. It is intended for the XRAY #309403 X4 Gear Differential to guarantee an accurate match and smooth function.
The housing includes small bleed vents for M2.5x8mm screws so excess oil can escape, helping to stabilise lubrication. The revised geometry centres the rear belt line to boost repeatability and forward traction, helping drivers maintain consistent handling.
