Description

The 4x4 Posi-Lok PSL500 replaces the vacuum-actuated differential shift system with a cable-operated actuator, giving the driver direct control of 4-wheel drive engagement from inside the cab. After engaging the transfer case, a one-inch pull of the Posi-Lok cable connects the right front axle to the intermediate shaft, engaging 4-wheel drive. The kit includes wiring for the 4WD dash indicator light, a heavy-duty cable system, and discreet dash mounting.
