I want to quiet the axle wrap on my T100--thinking about adding a full length leaf in place of the short leaf on the bottom of the stack; i.e- I don't want to raise the rear up any. Anyone ever done this, and has it worked? Will it increase or decrease payload?

 

I know a few that have used the Roadmaster Active Suspension and loved it.

I have the Roadmaster on my 2WD T-100...there might be a slight lift when it's unloaded. Since it's a dynamic setup and not a static setup like the AAL...it's a smooth ride.
