This is a set of Progressive 2 rocker arms for the Traxxas Revo monster truck. The key to Revo’s suspension performance is the progressive geometry built into the rockers. Increasing progressive rate over the stock progressive-1 rockers or long travel rockers is as simple as bolting on a new set. Progressive-2 provides additional firmness to reduce brake dive and body lean. Progressive-3 is even more progressive to further reduce body lean and brake dive and provide the most responsive handling.

Note that the package includes a set of red aluminum washers. These washers should be put between the ball ends of the suspension pushrods and the pushrod to increase the overall length of the pushrods. The pushrods must be slightly longer when using the P2 rocker set.
