2 Speed Electric/Spring Shift Kit

The 2 Speed Electric/Spring Shift Kit by SHIFNOID represents a significant advancement in automated transmission control for high-performance and modified vehicles. Designed for serious automotive enthusiasts and professional mechanics who demand precision gear engagement, this electric-assisted shifting system bridges the gap between manual control and full automation. Whether you're building a competition-grade drag car, enhancing a street machine, or retrofitting an older platform with modern shifting technology, this kit eliminates inconsistent shift timing and delivers repeatable, lightning-fast gear changes that manual or traditional hydraulic systems cannot match.

The dual-speed mechanism combines electronic actuation with mechanical spring return, ensuring both rapid engagement and fail-safe operation if electrical power is interrupted. The electric motor provides quick, controlled shift activation while the integral spring component guarantees positive disengagement and reset, eliminating delay and potential missed shifts during aggressive driving. Weighing just 2.8 pounds with compact dimensions of 9.3 x 3.8 x 12.1 inches, the SN6000 integrates cleanly into existing transmission housings without requiring extensive fabrication or frame modifications. The system is constructed to withstand high-load cycling and operates reliably across a wide range of engine power outputs, from mild street builds to extreme forced-induction applications.

This shift kit excels in vehicles equipped with non-electronically controlled transmissions—particularly adaptable T-56, TH400, and similar manual and automatic platforms common in custom hotrods, performance trucks, and vintage muscle car restorations. Installation requires basic mechanical aptitude and familiarity with transmission access; most professional shops complete setup in 3–5 hours. The electric component connects to a simple 12-volt power source with optional programmable delay timing for fine-tuning shift aggression based on your specific transmission calibration and driving style. For anyone serious about shaving tenths off launch times or achieving consistent gear transitions under boost, the 2 Speed Electric/Spring Shift Kit delivers measurable, repeatable results that justify its place in any dedicated performance build.
