This is an optional Hot Bodies 2 dot B Plate Arm mount, and is intended for use with the D817 V2 1/8 Off-Road Competition Nitro Buggy Kit. This Front Suspension B-Mount is a middle setting between the 1 dot and 3 dot mounts and can be used as a good all-around setup for the HB Buggy & Truggy 1:8 platforms. These B-Mounts allow racers to fine tune the front kick-up and roll center. Machined in lightweight aluminum and anodized black for added style.
