PML makes sand-cast aluminum differential covers, transmission pans, and valve covers.
If you're tired of
your 4-wheel drive failing, get the only system that puts you in control of your
front axle engagement system! 4x4 Posi-Lok is the patented cable activated
engagement device designed to replace the failure prone OEM (Original Equipment
Manufacturer) vacuum and electric front axle engagement systems. 4x4 Posi-Lok is
not a posi-trac or locker. 4x4 Posi-Lok is simple and easy to install and allows
you to engage your front axle from inside the cab. After engaging the transfer
case, a one-inch pull of the 4x4 Posi-Lok cable ensures the front axles are
connected. This system puts the driver in direct control of the 4-wheel drive
front axle engagement.
