Xray XB4 chassis weight set
Xray introduce this chassis weight set for the XB4 line of 1/10th buggies. Included are two 20g brass weights and suitable hardware to mount the weights in pre-shaped pockets right behind the LiPo battery packs. Adding weight in this position adds stability and traction and the parts fit both the XB4 4WD and 2WD buggy.
