When maintaining older XRAY XB builds, correct pins are essential to preserve steering and suspension behaviour. The XRAY 355291 Precision Flat Spot Pin set, at 2.5x12.8mm, is designed to refresh worn mounting points and return consistent feel to classic chassis.
The XRAY 355291 flat spot pin prevents rotation in its seating and helps maintain secure hold under load. For older XB models this reduces slop at junctions and improves repeatable geometry during track use. The accurate 2.5x12.8mm sizing makes these pins a dependable spare.
Prior to installation of XRAY 355291 pins, remove dirt and debris from locating holes and line the flat spot to the mating surface for maximal bite. Reinspect after a few runs and clean as part of routine maintenance to prolong service life and keep handling consistent.
