NXS-3 Speed Governor

Is Speeding Costing Your Fleet?

Excessive speed doesn't just risk lives—it burns fuel, increases engine wear, and invites heavy regulatory fines. Traditional limiters are jerky, unreliable, and easy to bypass.

The NXS-3 Solution

We don’t just “cut” the engine. The NXS-3 uses intelligent electronic throttle control to maintain smooth, oscillation-free speed limits. Drivers get full power for hills, but safety kicks in exactly when needed.
