Engineered for performance-minded hobbyists, the GPM Aluminum Pendulum Wheel Knuckle with 21mm hex adapter offers a weight-biased solution to improve wheel contact and reduce bounce. The design focuses on repeatable load transfer to the tyre for predictable traction in offroad conditions.
The hub-mounted stainless steel rolling beads add an incremental 44 to 64 grams per wheel, delivering a consistent downward preload that increases tyre bite during low speed crawling. Components use corrosion resistant stainless hardware suited to regular wet or muddy operation while maintaining mechanical integrity.
The pendulum architecture preserves a constant downward force through suspension articulation to stabilise motion and improve control. Validated compatibility includes Axial SCX10, SCX10 II, Gmade SAWBACK, SAWBACK 4LS, and KOMODO. For proper mounting confirm wheel inner diameter of 45mm and a 5mm thread hole before fitting.
