Wheely King Rock Crawler Conversion Set (Chassis, Gearbox, Wheels & Tyres)

Rock crawling is the latest RC craze to hit 4-wheel vehicles, but instead of the high-octane, adrenaline-fueled craziness of drifting from Japan, this low-speed, thrill-packed off-road adventuring comes from the mountain areas of America!

So what is crawling about? In stark contrast to the often two-dimensional world of circuit racing and drifting on pre-made, unchanging tarmac tracks, crawling gets you to attempt the improbable by attacking near-vertical cliffs, slick rock faces and piles of mountain rubble! Boulders, rock piles, mountain trails and footpaths are the typical location for competitions or fun meetings. Although in competitions the truck owners compete against each other, the magic appeal of rock crawling is that each driver competes against their own abilities, trusting in the strength of their equipment and the machine that is bringing them up the hill.

To make crawling more accessible to HPI customers, were offering a sweet Complete Crawler Conversion Kit especially for the Wheely King! This basically makes any regular Wheely King 4WD truck into our Crawler King kit (#102117 & #102118) and adds the excellent super-low gearing #87634 Reduction Gear Box for amazing hill-climbing capabilities!

The Wheely King has proven to be extremely popular with hobbyists, and its also become a great project truck for crawling enthusiasts to start a custom crawler build with. To make things even easier for crawling maniacs to get started, the Wheely King Crawler Conversion kit has just about everything thats needed to convert a 4WD Wheely King into a ‘King crawler!

The kit includes everything necessary to extend the wheelbase of the Wheely King, which will make it easier to go over obstacles. Extra-grippy HPI Rock Grabber tyres provide excellent traction on every surface, and are mounted on beadlock Rock 8 wheels. New lower shock mount positions allow you to fine-tune the suspension action for increased traction at both ends of the truck. Finally, the chassis is flipped around so the battery is at the front, putting the weight just where you need it to get over and across whatever stands in your way.

For extra stability when crawling up steep inclines, the conversion set includes new longer links that extend the wheelbase significantly over the stock Wheely King. Cool anodized aluminium links with tough pivot balls control the linkage and actuation, giving you loads of articulation for extreme angles!

Super-Low Gearing
The included #87634 Reduction Gear Box Set makes the gear ratio an astounding 174 to 1, for monster torque to climb the steepest of inclines! The stock Crawler King and Wheely King gear ratio is 23 to 1, so you will instantly see the impressive hill-climbing torque that the Reduction Gear Box Set will give you! The Reduction Gear Box Set will make the Wheely King much slower on level ground, but you will get the full effect of the gearing as you encounter steep approach angles and slippery, sandy rocks! (Comp Tip: Use a normal lower-turn motor such as a 19-turn or 27-turn motor to retain wheel speed as you approach an obstacle!)

Amazing Rock Grabber Crawling Tyres
HPI Racing Rock Grabber Tires are high grip tires designed for rough terrain. These rock crawling tires are moulded 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 tyre securely mounted on the wheel without the need for messy CA glue.

Cool Custom Beadlock Wheels
HPI Rock 8 beadlock wheels are included to give the Wheely King crawler a sweet custom look and allow you to change wheel weights, foams and tyres whenever you need to. Theres nothing like the look and style of real beadlock wheels, and these new mag style wheels look amazing and perfect for the ultimate scale crawler look!

Lower Shock and Link Mounts
To give you the best tuning options and increase the amount of ground clearance, HPI designers have included a new lower shock and link mount with several extra mounting locations. This gives you a multitude of options for tackling the toughest climbs, inclines and rock piles.

Monster Truck Body Mounts
For getting a cool custom style, you cant beat the option of attaching different bodies on your crawler. Weve included a full set of Savage-size body mounts for fitting dozens of different monster truck bodies! Simply use your Savage or other monster truck body right on, quick and easy, for a quick style change! No body is included with the conversion kit, so you can choose your own scale-look Savage body or any of the all-out competition bodies available.

All Hardware Included
Youll get nearly everything you need to make your Wheely King into a rock-pounding monster! Longer upper plastic links, longer lower aluminium links, pivot points, link and shock mounts, longer drive shafts, locking wheel hubs and Savage-type adjustable body mounts are included in the set.
