JKS PSL400 Cable-Operated Front Axle Disconnect Kit for Dodge Ram

The JKS PSL400 is a cable-operated front axle disconnect system designed to replace the failure-prone factory vacuum Central Axle Disconnect (CAD) system on 1994-2002 Dodge Ram 1500, 2500, and 3500 trucks equipped with Dana 44 or 60 front axles. This conversion kit puts 4WD engagement control directly in the driver's hands with a simple cable-pull mechanism operated from inside the cab.

Key Features:

• Replaces unreliable thermal/vacuum actuator with a durable cable-operated system
• Cast aluminum housing for the central axle disconnect system
• One-inch cable pull connects the right front axle to intermediate shaft via shift collar and fork
• Allows driver control of 4WD engagement from inside the cab without stopping
• Enables two-wheel drive low range (2WD-LO) for rear-only power with improved fuel efficiency
• Compatible with front differential lockers—disengage passenger side to eliminate wheel hop during turns
• Reduces front differential wear and right axle shaft breakage
• Complete wiring system ensures proper 4WD dash indicator light function
• Includes all necessary mounting hardware, gaskets, cable, switch adapter, and instructions

After engaging the transfer case, simply pull the cable one inch to lock the front axle and engage 4-wheel drive. Reverse the procedure to disengage. Installation typically requires one to two hours with basic hand tools. This system provides the reliability and control that manual locking hubs would offer, but with convenient in-cab operation.
