Made for committed RC drivers, the GPM Aluminum Pendulum Wheel Knuckle with 21mm hex adapter increases wheel-down force to improve stability and trail performance. This kit suits builders wanting a simple mechanical upgrade to tackle rough terrain with less wheel hop.
The added mass at each wheel helps lower the centre of gravity and broaden crawling angles. Stainless steel rolling beads contribute roughly 44 to 64 grams per wheel, providing steady downward pressure to improve tyre contact. Corrosion resistant stainless components hold up well in wet or muddy conditions for longer service life.
The pendulum-style knuckle sustains a predictable downward load for smoother articulation and control. Compatibility includes Axial SCX10, SCX10 II, Gmade SAWBACK, SAWBACK 4LS, and KOMODO models. For correct installation check that your wheel inner diameter is 45mm and thread hole is 5mm.
