You can have all the power in the world, but without grip, you’re just spinning your wheels. We’ve equipped this build with: 4.75” Super-Soft Compound Class 2 lugged tires.

Dual-stage inserts—firm inner for side-hill stability, soft outer for maximum wrap. The "6926363" Verdict

Heavyweight CNC aluminum beadlocks (adding 120g of unsprung weight per corner).

A crawler is only as good as its low-end grunt. We skipped the high-speed brushless setups for something with more "finesse." Build 6926363 runs a high-torque outrunner motor paired with a 15-tooth pinion, providing enough crawl ratio to literally watch the tread lugs wrap around the rock.

90mm internal spring shocks filled with 30wt oil to keep the tires pressed firmly against the rock face. Power & Control

The steering is handled by a 35kg waterproof digital servo. When you’re wedged in a V-notch, you need the power to move the rocks, not just the tires. The Contact Patch

This build isn’t about flashy light bars or chrome accents; it’s a masterclass in low-center-of-gravity (LCG) geometry and raw mechanical reliability. The Foundation: Chassis & Geometry

This build represents the "Pure" in rock crawling. There are no gimmicks here—just a perfect weight bias, a bulletproof drivetrain, and a chassis that thrives under pressure. Whether you're hitting the local competition circuit or exploring a virgin rock garden, Build 6926363 is the blueprint for technical success.
