If you want firmer steering response and a durable replacement part, the XRAY 362552 Aluminum Servo Saver Pivot Shafts are built for that role. Made for the XB4'21 lineup from Swiss 7075 T6 aluminum, these shafts balance strength with low weight. The extra 5mm of length lifts the steering geometry to help improve control under racing loads.
Choosing Swiss 7075 T6 aluminum reduces rotating mass while keeping the pivot area robust against wear. That material choice makes the XRAY 362552 a sensible upgrade for drivers chasing consistent steering feel and longevity from their servo saver parts.
These pivot shafts are produced to fit the XB4'21 series directly, enabling straightforward swapping with stock parts. The +5mm extension is intended to raise the steering link plane, which can aid precision on tighter or lower-traction surfaces.
