It's always a plus when we get something that exceeds our normal expectations. Many off-road enthusiasts buy Trail-Gear Creepy Twin transfer case shifters in order to drive in 2WD low—not realizing how much easier the twin sticks make it to shift in and out of 4-low. Access to 2WD low comes in extremely handy in tight switchbacks and other places on the trail where gear reduction is necessary, but 4WD isn't. These shifters are built to impress, with polished cast aluminum bases, black wavy heat-treated 1020 steel shifters, chromoly internal crosspin, and two shift knobs—one for 4.70 and the other for 2WD/4WD. Creepy Twin shifters also feature a splash-resistant oil breather, O-ring seal around each lever, and shifter gasket. To allow independent operation of the shift rails, you'll need to remove the interlock pin from the transfer case. Make 4-wheeling easier with Trail-Gear Creepy Twin transfer case shifters.
