83-93 Chevy/GMC S-Series Posi Lok 4x4 Actuator Kit

83-93 Chevy/GMC S-Series Posi Lok 4x4 Actuator Kit




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.

Heavy-duty cable system to replace the faulty OE vacuum system

Discreet dash mounting

Easy to follow instructions

Complete wiring system to ensure the 4WD dash indicator light functions properly.

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.
