Discover the 4x4 Posi-Lok advantage! Unlike vacuum-controlled OEM four-wheel drive engagement systems, the 4x4 Posi-Lok utilizes a cable-operated setup. This means the engagement system won’t fail due to freezing temperatures, cracked vacuum lines, or total loss of vacuum. Simply activate the cable-operated 4x4 Posi-Lok system via its dash-mounted switch for quick, positive four-wheel drive engagement. The beauty is in its simplicity! Summit Racing carries 4x4 Posi-Lok axle engagement systems, replacement cables, shift forks, and more. Shop now!
