Element's Enduro Gatekeeper Builder's Kit is a 1/10 four-wheel-drive crawler kit, built by you and sold without motor, pinion, electronics, wheels or tires.

It comes with an 87T 48P spur and the Stealth X gearbox, which overdrives the front axle, so your overall ratio depends on the pinion and motor you add. The axles take 12 mm hex wheels, and the shocks come filled with 30 wt oil. Start with a 48P pinion that suits your motor, then pick wheels and tires, since tire size changes how the gearing feels on the trail.

Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.

Gearing parts

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft. Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

The kit ships without motor, pinion, ESC, servo, receiver, wheels or tires; Element's page lists a 540-size motor with a 48-pitch pinion, wheels with 12 mm hex mounting and tires among the items needed to complete it.

Element's spec table prints 'Internal Gear Ratio: varies' because the Stealth X gearbox turns the front and rear axles at different speeds, so the transmission and axle ratio and the final drive are left blank.
The manual names an 87T 48P spur (#9654), a fixed 20T-28T-52T front train with the 27T-53T rear pair fitted (5.7% front overdrive), and 30T/8T ring and pinion gears in both axles.
Those work out to about 9.75:1 after the spur at the front and 10.31:1 at the rear; the included 26T-54T rear pair (11.83% overdrive) gives about 10.90:1 at the rear.
The manual's gearbox step shows an 18T pinion (#1336) marked 'Not Included'.
Element's comparison chart lists 1.9 x 4.65 in tires for this kit, but the product page lists wheels and tires as not included, so no tire size is shown here.
