Traxxas 10727-BLK WideMaxx Rear Suspension Arms

The Traxxas 10727-BLK is the complete rear suspension arm set for the Mini Maxx WideMaxx suspension kit: upper left, upper right, lower left, and lower right arms in black. These are the arms used with the #10790 WideMaxx kit — they are longer than the stock arms and are not a substitute for standard Mini Maxx arms.

Widening the rear track is what keeps a monster truck planted under power. The extra width resists the body roll that unsettles the truck mid-corner and cuts down on the traction-rolling that comes with grippy tires on a narrow chassis. Paired with the matching front arms, it transforms how stable the truck feels at speed.

Arms are also the part most likely to crack on a bad landing, so a spare set on the shelf is cheap insurance against a cut-short session. Note that a complete WideMaxx conversion also needs the extended half shafts from the #10790 kit. Package includes four rear arms.
