This never before seen design strengthens the input by nearly 100% and provides maximum contact area to prolong coupler life and prevent strip-outs. We offer gear kits, clearanced housings and fully built units. 21 or 23 Spline.

This 3-wire, 4-pluse magnetic pulse amplifier will convert ANY Toyota vehicle with a standard 22x1.50 mechanical speedometer drive to an electronic speedometer system. Features a standard Toyota VSS Plug for your convience. The Applications are unlimited, converting both 4WD and 2WD 22x1.50 mechanical speedometer setups to electronic 3-wire, 4-pulse speedometer setups. Now installing a Tacoma Engine into a Hilux or Land Cruiser is a snap! Works on both Gear and Chain Drive Transfercases!
For 1992-95 V6 Applications, when converting to a Gear Drive T/Case Setup, the only previous option was to use a 1992-95 Factory Toyota 4cyl 5-speed Gear Drive T/Case VSS, that sells for $210. The New Marlin Crawler VSS saves $150 on a 1992-95 V6 Transfercase Conversion.
