Electric Solenoid - Quarter Stick

The Electric Solenoid - Quarter Stick from Biondo Racing Products is a 12-volt shifter solenoid designed for street and racing applications using Hurst Quarter Stick transmission shifter kits. This component automates gear engagement by converting electrical impulses into mechanical action, allowing drivers to shift with precision and repeatability without full manual lever manipulation. It's ideal for bracket racers, street performance enthusiasts, and serious tuners who demand faster, more consistent shift times and want to eliminate human error from the shifting equation.

Built as a complete kit with mounting bracket and relay, the Electric Solenoid - Quarter Stick operates on 12-volt vehicle electrical systems and functions via electromagnetic activation to engage gear changes instantaneously. The solenoid's electromagnetic coil generates the force necessary to move the internal plunger, which mechanically couples with the Hurst Quarter Stick shifter linkage to command upshifts or downshifts. Weighing 2.95 lbs and measuring 4.4 x 3.3 x 7.7 inches, the assembly is compact enough to fit in most engine bays or interior locations without requiring extensive fabrication, while the included relay protects the solenoid from voltage spikes and ensures reliable circuit management across repeated shift cycles.

This solenoid excels in dedicated race cars, street machines, and performance vehicles running Hurst Quarter Stick shifters where lag-free automated shifting is non-negotiable. Installation integrates directly with the Quarter Stick lever arm and Hurst bracket system; users must wire the 12V solenoid through the included relay to their vehicle's battery and ignition, then route activation signals from a transmission controller, button switch, or RPM-based module. The kit's plug-and-play design with mounting hardware makes it accessible to both professional builders and experienced mechanics comfortable with electrical integration and shifter calibration.
