This kit mounts a plate to on top of a Capra steering axle and relocates the servo allowing for a small 3-4s pack to be mounted on the axle. Shifting more weight forward and increasing rig performance in the process. Great for small custom comp style builds that use smaller batteries where space inside the chassis is limited. Kit includes the carbon plate, Aluminum Servo mounts, and hardware. The battery can be attached with your choice of a Velcro strap or adhesive pads (not included). The carbon plate has a few color choices and there is a Link Riser option for those running this kit on a 4ws rig.
