New from Xray come two shock tower reinforcement parts for the XB4 buggy. First up is the rear shock tower protector that is designed to save the upper part of the shock stay from becoming damaged in upside down landings. The part not only protects the carbon layers from de-laminating but also minimises the chances of cracking the shock mounting holes. The second new part is the roll centre brace that protects the inner camber rod mounting positions during hard impacts. Both parts are available separately and are made from high quality hardened steel.
