The Perm-Lok permanently engages the Central Axle Disconnect (CAD) system and couples both front axles permanently. Once installed, the front axles will not pull until the transfer case in engaged.
4x4 Posi-Lok replaces the vacuum actuator with a cable operated actuator that puts the driver in control of the engagement from inside the cab. After engaging the transfer case, a one inch pull of the 4x4 Posi-Lok cable connects the right front axle to the intermediate shaft using the shift collar and fork, and 4-wheel drive is engaged! Simply reverse the procedure to disengage 4-wheel drive. 4x4 Posi-Lok also works great with lockers! When the front axle is locked, you can disengage the passenger side in order to make turns without wheel hop.
  • Ideal for Offroad Vehicles, and Vehicles that never see the road
  • Includes: New high-strength aluminum housing with gasket kit and New machined inner push rod to lock the central axle disconnect in an engaged position
