SP electronics manufactures two different Electronic Gearbox Kits for GO-KARTs, an EQS model applicable on single-cylinder engine GO-KARTS, and another model, also EQS, applicable on two-cylinder GO-KART engines.

Both models are Battery-free Electronic Gearbox Kits, applicable on engines with PVL/SELETTRA ignition. EQS (Easy Quick Shifter) is an electronic device used in high speed vehicle sports to shift into higher gear without closing the throttle or using the clutch. The Kits consist of a single electronic control unit (eBox EQS), an electromechanical knob sensor and Plug&Play wiring for connection to the GO-KART’s original electrics.
