The XRAY 325101 Narrow Active Differential Set is built to upgrade the XB2 buggy's front-end behaviour by improving how power is transferred through the front gears. It helps produce steadier handling when accelerating out of turns.
The design uses angled internal segments so the gears engage more effectively under load, boosting forward traction and smoothing acceleration. This results in a more consistent driving feel across a range of surfaces.
Be sure to install all four internal satellite gears to preserve the differential's intended performance and strength. The set does not include ball bearings, so source the correct bearings before assembly.
