New, innovation and new patent • the XRAY Multi-Diff™. This new unique front diff has three different settings: one-way / one-way solid / full-time solid axle. You can easily use the Multi-Diff™ as a standard one-way (left and right outdrives turn independently off-power), or lock the one-way out drives (both left and right outdrives turn together off-power), or you can fully lock the Multi-Diff™ and it will work as a full-time solid axle.

The new lightweight one-way outdrives manufactured from Hudy Spring Steel™ have a hex hole machined at each end. A lightweight machined steel hex-style locking axle can be inserted into both outdrives to lock them together and create a solid one-way, which means both outdrives turn freely together as a one-way (at the same time), thus creating a solid one-way off-power.

To create a full-time solid axle, a pin is inserted through aligned holes in the main aluminum body of the Multi-Diff™ and the steel locking axle. This will lock the outdrives completely, creating a full-time solid axle.

This Part# 305102 set fits ONLY the XRAY T1FK05.
This set does NOT fit the XRAY T1, T1Evo2, T1R, T1M, or T1FK. The Multi-Diff for those cars is Part# 305103, and is currently IN STOCK.

This appropriate Multi-Diff is replacing the discontinued Solid Axle (Part# 305180) for all cars.
