CPP’s new triangulated 4-link kit will bring your 1955-57 Chevy car’s rear suspension into the 21st century. This triangulated design keeps the axle centered without the need for a panhard or track bar. The four adjustable bars are positioned to provide ample room for routing your exhaust over the differential. With 9 inches of travel, this rear suspension delivers smooth ride quality. This new kit is compatible with CPP pro touring and high-clearance sway bars, and it requires no modifications to the floorboard.For ease of installation, CPP recommends using our 9” rear housing with the brackets already welded on. If you are welding onto your own 9” or factory rear end, we advise using the weld fixture 12202 for a more straightforward installation. Please note that OEM factory rear ends will require bracket kit 12203. This kit is not compatible with 10 or 12 bolt rear ends.
Upgrading the rear suspension on a classic Tri-Five Chevy is one of the best ways to improve ride quality, handling, stance, and overall performance. In this video, The Challenged One walks through the installation of a CPP Tri-Five 4-link coilover suspension kit on a 1957 Chevy, replacing the original leaf spring-style rear suspension with a more modern 4-link coilover setup. The factory rear suspension on a 1955–57 Chevy was built for the roads and driving expectations of its time. While the original design works well for a stock cruiser, today’s builders often want more adjustability, better control, improved traction, and a cleaner stance. That is where CPP’s 4-link coilover suspension system comes in.
Hello Billy and thank you for showing interest in our products. The kit in question will not work on the GM 10/12 bolt rears. This kit will work with the factory rear end and the 9” rear.
What is the length of the upper and lower control arms in this kit? Do you have anymore detailed info?
Hello John and thank you for reaching out. The uppers are about 16.25” collapsed and the lowers are about 20.25” collapsed. These will have about 1” of adjustment.
