Re: No Limit Trailing Arm Rear Suspension

Panhard Rod Info

We call this a "Low Roll" Panhard rod, because of it's ability to lower the Roll Center of the truck. You need to know that doing this may actually increase the amount of body roll in a given corner (all other factors being equal, compared to a higher roll center). So, along with this we have spaced the shock/spring assembly farther outboard to combat/control the extra roll forces.

We have to start out understanding how tough it is to get trucks to handle great. High CG, Low rear weight %, and a high % of rear unsprung weight, are the three performance killers in the average truck. So, taking the sports car route of "low body roll" - flat corners, isn't going to work so well. We can use the body roll forces to basically stuff the outside rear tire into the pavement, and hold the truck down through the corner. Most trucks would notice a net reduction in body roll with this suspension system, as compared to a stock set up, but it is not a 'stiff', 'flat', low travel design. That kind of thing hes been proven to be less effective.

Here are a few more picts of the installed Panhard bar on our project truck
