Four Link Suspension

Drag race four link suspension use spherical rod ends for strength and extreme adjustability. The drag race bars when set up correctly form an open ended triangle to permit you to change what is called the cars "instant center" (theoretical point that the tires push)to achieve the ultimate in traction control.

Frame modifications are required to install a 4 link. Unless you plan to turn quarter mile times faster than high 9s you may wish to consider Ladder link bars (AKA double adjustable ladder bars) as they are much easier to install and set up. I have driven my coupe into the 9s using stock leaf springs and ladder bars. Yes a 4 Link will give better traction than ladder bars but only if you spend considerable time to adjust and readjust them.


Application: Universal fit drag race traction bars. Use with coil-overs
