Blackbox Standard

The Current BlackBox Build Time is 12 Weeks

The BlackBox Planetary Gearbox
The BlackBox is a compact planetary gearbox that fits between your existing transmission and transfer case, giving you the best of both worlds: a 1:1 high range for highway cruising, and a deep 2.72:1 low range for serious off-road control. It’s built for 4x4 enthusiasts who demand more precision, traction, and slow-speed finesse than stock systems can deliver.

Engineered for Strength
The BlackBox was the first planetary gearbox to feature bearing support at both the input and output of the main shaft. While other gearboxes rely on your transfer case’s input splines and bearing to center and carry the entire output load, we do it differently. The BlackBox uses a massive 80mm roller bearing at the output—delivering unmatched strength and reliability.

Game-Changing Performance
Adding a BlackBox to your rig is a transformative upgrade. If you remember the control and traction boost from installing lockers or new tires, expect that same level of performance gain again—only this time, from your gearing.

The Right Gear for the Job
Running the right combination of gear ratio, RPM, and wheel speed is essential. Too deep a crawl ratio and your engine may bog down before building momentum. Too tall, and you’ll find yourself bouncing off obstacles with brute speed instead of precision.

The key isn’t just low gearing—it’s gearing options. The BlackBox gives your 4x4 the ability to tackle everything from slow, technical crawls to fast-paced trail runs with confidence and control.
