4x4 Posi-Lok Dodge

W-Series Pickup, Ramcharger, Trailduster

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.

Common Problems With The OEM System-Vacuum Actuator

• The colder the temperature, the longer it will take to engage.
  
• If the front differential becomes submerged, the TLA temperature will cool and the 4-wheel drive will disengage.
  
• The TLA unit can cause excessive wear on internal components in the differential and may cause other electrical problems.
