Specifications: * DPDT ON/OFF/ON momentary switch * Single independently wired incandescent light * No rear barrier between terminals * Rated 20 amps at 12 V Please note: Switches are meant to be wired independently from the factory wiring.

Hybrid Racing Short Shifter Assemblies

Hybrid Racing offers short shifter assemblies for a variety of applications, including many Honda© and Acura© models from 1988 and up. These economical units feature an unparalleled level of adjustability so drivers can tweak every aspect of the shifter to suit their own preference. The shifters' frame is constructed from TIG-welded, powdercoated, 1000 Series steel. The anodized upper and lower rocker assemblies are now made of single pieces of aerospace-grade aluminum, with custom sealed ball bearings to reduce friction. The new V2 shifter, for instance, is 60 percent smoother than the original version, requiring much less physical effort to row through gears all while being significantly lighter. Shift throw adjustment is achieved using two threaded cable attachment pins, meaning fine tweaks can be made to shift throw, allowing you to dial in the exact throw that suits your shifting style. Each attachment pin features a wear-resistant Delrin© pivot cap for sturdy, quiet operation. New dual, zinc-plated extension springs replace the OEM-style torsion centering spring for better-centering action and a more direct feel. The front/back throw and left/right throw can be adjusted independently; and most models include shift knob height adjustment. Simple single-bolt height adjustment design (borrowed from the popular K-swap shifters) allows the knob to be adjusted higher or lower than stock (within a 1.5 in. total range) with only a 5mm Allen wrench. Now you can tweak the shifter's throw AND knob position independently until the shifter functions exactly the way you want it to. Enjoy smooth, precise, and direct shifts with a new short shifter assembly from Hybrid Racing!
