CNC machined out of a piece of 6061-T6 by BP Fabrication on a Haas CNC machine. The panhard mount will work on all popular midget chassis in production including: Spike, Bullet, Boss, Ripper, XXX, and KING! The backside is pocketed out to have the nut recessed inside so you only need one wrench to tighten or loosen up the mount. These are also available in black or plain finish!
