1955-1957 Chevy Triangulated 4-Link Kit is a very popular kit as it does not require a Panhard Rod. Bars are fully adjustable, 1-1/4? x .156 tube with 3/4? stainless adjusters and urethane bushings, angled and straight chassis brackets, tabs and hardware. These kits are available in plain steel or polished stainless steel tubes. These kits are also available with a full 9 inch housing, gears and disc brakes. Note - the brackets are weld on.
