Aluminum rear lower suspension holder for the FRONT of the rear suspension. CNC-machined from 5mm premium Swiss 7075 T6 aluminum. Ultra-strong construction provides very long lifespan and durability in even the most extreme racing conditions.Aluminum lower suspension holders with Integrated Suspension Settings (I.S.S.) allows for quick & easy suspension geometry setting. This XRAY concept was first introduced in the very first XB8 and has been carried over to the 1/10 scale XB2.Using eccentric suspension bushings inserted into aluminum suspension blocks, along with additional suspension shims, the XB2 suspension geometry can be completely adjusted.
