Traxxas T-maxx 2.5R
The T-maxx 2.5R (4902) is what happens when a Traxxas Tmaxx and Traxxas Revo meet - Traxxas took their popular T-maxx monster truck and improved upon it even further, adding a TRX 2.5R Racing Engine, proven Revo-spec driveline, and the new OptiDrive 2speed forward/reverse equipped transmission.
The Traxxas T-maxx 2.5R features a thicker 4mm 6061-T6 aluminum chassis that reduces flex. The TRX 2.5R engine is equipped with an oversized finned aluminum cooling head to dissipate more heat under grueling off-road conditions. The entire Tmaxx 2.5R driveline has been upgraded to Revo specification with super-duty sealed driveshafts, Revo axle carriers with large rubber sealed bearings, and sealed pivot balls. Seals keep out the dirt for longer component life and smoother running. The differential housings, engine mount, bulkheads, shock towers, and body posts have all been strengthened to help take the abuse we know you will put it through.
