Overview

This set lengthens the wheelbase of the Wheely King by 2 ¼" to help provide the stability needed for extreme rock crawling. Anodized aluminum lower links are durable and give the Wheely King an authentic crawler looks and ground clearance is extended with high link suspension mount brackets.

To help maximize the weight layout for rock crawling, the conversion set comes with a new servo mount that allows the battery to be moved forward in the truck. Diff lockers are included to for both differentials, effectively locking the front and rear diffs for extra traction. Also included are convenient body mounts and hex hubs that allow the Wheely King Crawler to be compatible with a wide variety of bodies and wheels.

The Reduction Gear Box Set bolts right into any Wheely King for a perfect fit. It contains a tough metal case, ball bearings and all-metal gears for extra durability. The gear ratio is transformed from 23:1 on the stock truck to a whopping 174:1 after the installation. This Reduction Gear Box Set is perfect for rock crawling because it delivers stump pulling torque and the power to climb any slope.

Rock 8 Bead Lock Wheels are designed for high performance in rock crawling conditions. The tire is held on with bead lock rings to keep the tire securely mounted on the wheel without the need for messy super glue. Each ring is made from stainless steel, making them extra heavy to keep them firmly planted on steep terrain.

Rock Grabber Tires are high grip tires designed for rocky terrain. These rock crawling tires are molded with sticky S compound rubber for excellent grip on all kinds of rocks. The blocky tread pattern wraps around the sidewall of the tire for extra grip in challenging conditions. These are true bead lock tires, made to fit HPI rock crawling wheels using 6-hole bead lock rings to keep the tire securely mounted on the wheel without the need for messy super glue.
