1/10 Enduro Comp Fox Builder's Kit (ASC40129)

Introducing the 1/10 scale Enduro Comp Fox Builder’s Kit, a competition-ready rock crawler designed for serious crawlers who want to tune through every gate. It pairs a carbon fiber flat-rail chassis with machined aluminum braces for a lightweight yet rigid frame, and an 8-degree Delrin angled skid plate to improve breakovers and ground clearance. The drivetrain centers on the Stealth X transmission with overdrive gears and a forward-biased aluminum motor mount, placing motor weight toward the front for a balanced 60/40 weight distribution that enhances stability on challenging terrain.

High-clearance portal axles deliver almost an inch of extra ground clearance over standard straight axles, with all-metal gears and bearings for durability. Factory Team upgrades like steel pivot balls, high-clearance links, and threaded aluminum shocks, plus telescopic driveshafts, machined input pinions and gears, metal ring gears, a machined steel top shaft, and servo-on-axle steering, round out a platform built for tough rock courses and ample tuning options to adapt to different terrains.
