For fans of older XRAY XB models, fitment and stability are key to enjoying classic kits. The XRAY 355291 Precision Flat Spot Pin set, sized 2.5x12.8mm, provides a straightforward replacement part to tighten up worn mounts and maintain predictable steering and suspension action.
The flat spot on each XRAY 355291 pin prevents unwanted rotation and helps pins remain seated under load. These pins match older XB assemblies and give consistent alignment through fast sections or tight corners. They are a simple, effective way to refresh ageing hardware without major rebuilds.
When fitting XRAY 355291 pins, clear any dirt from the chassis holes and line the flat spot with the mating surface for the best hold. After a few runs, recheck for looseness and clean off debris. Simple inspections will keep these pins performing well over many sessions.
