This pendulum wheel axle weight provides low-mounted mass at each wheel to improve traction and vehicle stability during slow rock crawling. The brass pendulum is narrower at the top and wider at the bottom to keep mass downward, and the Delrin-collared bearing allows free pendulum motion across steering and suspension movement.
Fit and performance details: mount the pendulum and 21mm hex on the outer drive portal to retain a low chassis centre of gravity; the 21mm widened hex increases wheel offset by 16mm versus stock, and one pendulum plus hex assembly weighs 136 grams. Ensure wheels have a 45mm inner diameter and a 5mm thread hole for proper installation.
The box includes all hardware for fitting: 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.
Select this pendulum weight to reduce roll and increase wheel bite on technical climbs; confirm wheel bore and thread size before purchase.
