This pendulum wheel axle weight is made to increase low-mounted mass at each wheel, improving stability and traction during slow-speed rock crawling. The brass pendulum is shaped to keep mass low, and the Delrin-collared bearing provides free swinging motion across steering and suspension angles.
Key notes on fit and performance: the pendulum assembly with 21mm hex fits on the outer drive portal so the chassis CG stays low, the widened 21mm hex gives 16mm more wheel offset than stock, and a single pendulum assembly weighs 136 grams. Required wheel specs include a 45mm inner diameter and a 5mm wheel thread hole.
The supplied kit includes installation parts: 21mm hex adapter (2 pcs), stainless steel pin 2x10 (2 pcs), 5mm spring steel shims (2 pcs), 5mm metal washers (2 pcs), 19mm stainless steel hex socket screws (2 pcs), and a central bearing with Delrin collar.
Use this weight to lower roll and increase wheel bite on technical lines; always confirm wheel internal diameter and thread size before fitting.
