Our Camburg Race Series lower links are one of the highest quality and strongest on the market today. CAD designed they are fully internally ribbed and gusseted, CNC laser cut and MIG welded in house. These are the same design as our  KINETIK race trucks use. They have 1" uni-balls at the front and rear pivots. Our link design lowers the shocks into the link giving you more ground clearance under the link.  Links include uni-balls only, spacers and hardware are sold separately. These require your shocks to use 3" longer lower rod ends with 1/2" x 1.50" spacers.
