The Perm-Lok permanently engages the Central Axle Disconnect (CAD) system and couples both front axles. Once installed, the front axles will not pull until the transfer case is engaged.

Installation is super easy and can be completed in approximately 10 minutes.

Ideally suited for fleet operators, and emergency vehicles.
