This is the RPM Black True-Track Rear A-Arm Conversion for the Traxxas T-Maxx 2.5R, T-Maxx 3.3, and E-Maxx 16.8.

Rear toe angles are nearly impossible to set accurately and there isn't a gauge currently made that can tell the T-Maxx or E-Maxx owner, if each individual wheel's toe angle is set correctly in relation to the chassis. RPM’s rear end kit completely eliminates the rear toe link, locking in the rear toe angle at a solid negative 1.5 degrees per side for a total rear toe of negative 3 degrees.

RPM’s design retains the stock upper pivot ball in the RPM axle carrier to allow precise camber adjustments while the lower pivot ball has been eliminated in favor of a rock-solid, beefy 4mm diameter hinge pin that locks in the rear toe angles for race winning consistency. All aspects of the RPM rear end conversion have been beefed up for rugged durability and slop free movement throughout its range of travel.

Additionally, RPM has incorporated our oversized bearings into the axle carrier design, providing 2mm more bearing contact with the axle while doubling the bearing load rating & tripling the fatigue rating over the stock bearings. So does all this add weight? Not a single gram! The entire RPM rear end kit weighs in exactly the same as the stock components that are replaced!
