The XRAY 323353-H Hard Composite Rear Upright is made for drivers tuning their XB2 2017 Dirt Edition chassis. The hard composite construction stands up to rough running while holding suspension geometry precisely. Seven upper roll center positions give you the control to tailor rear behaviour on medium to high-grip surfaces.
This part is engineered for competitive weekends and heavy practice sessions, giving predictable rear response when entering and exiting corners. Fit it if you want a firmer, more consistent rear feel on grippy dirt tracks.
