"On-The-Fly" 4-WD Kit For GM Pickups

"On-The-Fly" 4-WD Kit For GM Pickups PICKUPS Accessories 22-5-6 If the front axle on your 4-WD GM pickup won't engage, or takes too long to do so, you'll want to check out this new kit that gives you instant 4-WD "on-the-fly". The "Posi-Lok" system is a manual cable-actuated system that replaces the troublesome "Thermal Linear Actuator" (TLA) found on GM pickups, 1988 and newer. The problem is the liquid inside the GM unit takes 5 to 10 minutes to heat up in order to activate the 4-WD, and it's even slower in cold weather. Also, the front axle disengages any time you turn the truck off. The kit replaces the TLA with a new push rod activator. A clevis attaches the push rod to a bell crank, which is activated by a cable that runs into the cab. There, it's fitted with a locking T-handle that mounts on a bracket under the dash. Installation takes about an hour and just about anyone can do it, the company says. Sells for $149.20 for full-size pickups; $84.95 for S-10's.
