I installed some of RCP beams in the Mack tonight. It was said on his youtube vid that installing them may limit the side to side articulation slightly. However this truck saw lots of abuse in the dirt over the years and has sloppy pivot points in the suspension. The new beams went in and the slop allowed them to move around quite well. I did run a quick file thru the bottom 2 holes to "oval" them just a little so that each corner of the tandem can move more independently. Both axles have the stock plastic travel stops cut off them and the suspension moves plenty. These will also keep traction even across the tandems being that its now a true center point suspension . I removed the shocks as well to get just a little more travel. doing so I needed to install a RC4WD driveshaft as the tamiya dog bone will not allow for the extra travel it has now
