This poly bushing and sleeve joint is ideal for building inexpensive three link (also known as tri-link or wishbone) suspension systems. Two of these joints are used on the frame end of the link. They provide rigid control of side to side motion yet rotate freely up and down. The link would typically use a flex ball joint or Heim joint on the axle end.

The kit consists of a DOM sleeve with two poly bushings and an inner sleeve. The DOM sleeve is 1 7/8" in diameter. The inner sleeve accepts a 9/16" bolt. The assembled width of the joint is 2 5/8", making it directly compatible with standard control arm brackets.

The joint is pictured assembled and disassembled for clarity. Joints are sold individually.
