1/10 Enduro Builder’s Kit 3 (ASC40135)

Enduro Builder’s Kit 3 is a 1/10-scale rock crawler kit designed to tackle rugged trails with confident control. This edition updates the lineup with GKS shock towers at the front and rear, and shock-mount inserts that let you adjust shock angle, droop, and ride height without changing spring preload, giving you flexible tuning for a variety of terrain.

Power and handling come from a forward-biased Stealth XF gearbox that lets you independently adjust front and rear drive ratios across three levels, with included overdrive gears and an optional one-to-one setup for equal drive. Behind-the-axle steering improves approach angles and front-end clearance, while the aluminum track bar mount and high-clearance links with steel pivot balls provide rigidity and smooth articulation. Factory Team shocks, steel wheel hexes, and a range of machined and steel components contribute to durability, and a water-resistant receiver box helps protect electronics in wet conditions—together creating a rugged, upgrade-ready platform for serious crawlers.
