Kenny Talks Tech on 3-Link versus 4-Link Mustang Rear Suspensions

In this tech video, Kenny shares a wealth of knowledge on the common 4-link and 3-link rear suspensions used on late model Ford Mustangs. He also talks tech on the primary differences, the best way to approach upgrades, and what he would do or does to improve them.

Thank you Kenny. I wasn't convinced before that a torque arm was the right solution for my SN95. You showed me why.

For those interested, the K-link or AGS 4.5 is commonly know as a Mumford Link. There isn't much information about it, but basically it lets you set the roll center well below the axle and theoretically below the ground. The two lower links that extend out to the struts set the angle at which the roll center meets in the center. The triangle center linkage allows the mechanism to clear the ground and angle back towards the chassis. Supposedly some UK club racers have been using this system for almost a decade with great results. It was developed by an engineer name Michael Mumford.

You are spot on Travis. This Mumford variation is modified and designed specifically for the S197 Mustang, but there are several variations that have been used in professional racing in the EU as you noted for decades. Most of them with slight differences for the application.

Great information..Thank you Kenny..
