ROLL CENTER EXPLAINED by Jake Burkey- Tech Tuesday

This time on Tech Tuesday Jake Burkey of the Busted Knuckle Off Road Shop is going to explain everything you need to know about Roll Center and Roll Axis and how they affect your Triangulated 4 Link Suspension as well as a 3 Link or Parallel 4 link with panhard bar.

Roll Axis/ Roll Center
The roll axis and roll center of a vehicle's suspension system determin how much body roll or sway the vehicle will experience when cornering. The roll axis is the imaginary line drawn between the two points made where the lower links would eventually connect and where the upper links would eventually connect. In the case of a suspension with parallel links the roll axis line is simply going to be parallel with the parallel links. The point along the roll axis that is directly above the axle center line is the roll center.

Body Roll
The distance between the roll center and vehicle's center of gravity becomes the leverage factor for body roll. In other words, the further above the roll center the vehicle's center of gravity is, the more body roll the vehicle will experience during a turn. The closer the roll center is to the center of gravity, the less body roll the vehicle will experience and, in theory, if the roll center is on the center of gravity line, the vehicle would have no body roll.
