1/10 VS4-10 Straight Axle 4x4 Rock Crawler Builders Kit (VPS09022)

VS4-10 1/10-scale Straight-Axle 4x4 Rock Crawler Builders Kit is a purpose-built, scale-focused platform for serious crawlers. It pairs a VFD transmission with a forward-mounted motor and sturdy F10 straight axles to deliver strong torque, smooth articulation, and lasting durability. Out of the box it includes a 6.5% overdrive to improve turning and climbing, while the modular transfer case with replaceable bearing plates supports optional gear ratios. It’s compatible with 540-size brushed or brushless motors, and ISD10 driveshafts with machined CV joints ensure efficient power transfer to the wheels.

The chassis blends rugged practicality with scale detail: a heavy-duty steel C-channel frame with an integrated battery tray, dual servo mounts, winch routing, and rock sliders with replaceable outer portions. F10 axle housings, 49-degree steering, and universal shafts provide solid, tunable performance, while Incision 90mm S8E shocks deliver controlled damping with 8mm bore, dual X-Ring seals, and threaded bodies. A front 3-link with panhard keeps the servo out of sight yet preserves full suspension travel, and the overall design supports a robust, tunable platform ideal for realistic trail crawls and challenging terrain.
