SCRATCH & DENT: SA-10X Ultimate axle kit with Steering Fusion Torque Vectoring, 360 Tank Turn Capability, Direct Mode Capability, Front Skid Plate

Be ahead of the curve with active torque vectoring technology, only from Sparc Drive. Unlock super-tight handling and unbeatable off-road traction—without the drawbacks of open diffs or selectable lockers.

This next-generation axle kit is packed with state-of-the-art drive technology including regenerative steering differentials and real-time control logic. Built to tackle challenging terrain, Sparc Drive axles always maintain a "locked" state (even while torque vectoring) for instant traction response to keep you moving forward.

Conquer every corner with the only axle on the market that crawls like a locked diff while simultaneously turning on a dime. Say goodbye to the hassle of switching between complicated traction modes or dealing with clunky lockers and auxiliary servos. With our patented Steering Fusion technology, you get to enjoy the best of both worlds, all the time.

This Ultimate axle kit includes front + rear axles, a Steering Fusion electronic control module with tank turn capability for low-traction surfaces, and a nylon front skid plate,

Tank turn mode automatically engages after a short delay (user customizable) when the vehicle is at a stop and the steering is centered.  Once engaged, steering inputs will command a zero-radius turn while on a suitable smooth / low-grip surface. When the axles detect a net forward or reverse movement, the system will revert back to normal steering. 

Have an extra channel on your radio?  Connect the direct mode wire to an available channel and take direct control of the torque vectoring motors for ultimate control flexibility.  Direct mode adds a whole new dimension to crawling.  Unplug the direct mode wire and Steering Fusion's automatic torque vectoring takes over again.       

Please consult the user guide for additional information.  

This axle kit works with your existing 2 (or more) channel RC radio controller and is compatible with Element Enduro, Axial SCX10, SCX10.2, SCX10.3 Builder's kit, SCX10 Pro, and similar AR44 / AR45 (straight-axle) style 1:10 scale crawlers running 2S or 3S batteries.

Each axle is built with precision steel gears and ball bearings for durability and is hand-assembled in the USA.

FAQ:
Do Sparc Drive axles use brakes or clutches to vector torque and limit wheel slip?
Unlike other traction control systems, Sparc Drive axles are fully gear-driven. Sparc Drive does not use brakes, clutches, or any other type of friction components in its axles.

Do I need a radio transmitter/receiver with 3 or more channels?  What about servos? 
Sparc Drive’s Steering Fusion control module is plug-and-play compatible with 2-channel radio systems, and unlike other drive accessories, no servos are needed.  The Direct Mode capability included with our Ultimate kit provides an additional wire to allow direct control of the torque vectoring motors using a third channel. This gives maximum control flexibility but requires more driver attention to operate. When the direct mode wire is unplugged, Steering Fusion's automatic torque vectoring takes over again.   

Will Sparc Drive axles work with over/under drive transmissions?
Yes. While the cornering benefit of overdrive can't compare to our real-time torque vectoring, the functionality of our axles is not affected by having different front vs. rear driveshaft speeds. 

Are Sparc Drive axles compatible with DIG?
Yes, Sparc Drive axles work well with Dig units. During a typical dig turn, the rear wheels are usually dragged around like dead weight by the front wheels. With Sparc Drive axles, the rear wheels will automatically counter-rotate in the direction of the dig turn to help pivot the vehicle in the intended direction. Sparc Drive works out of the box with all existing Dig transmissions. No additional settings or equipment are needed.
