The Mako range of 12V electric winches are a superb product designed for 4WD use.
These are a must for 4WDs used on beaches or in sandy outback conditions. They allow you to automatically deflate all four tyres at once, saving 10-12 minutes each time.
An affordable 12 volt impact wrench (rattle gun), suitable for use on vehicles up to large 4WDs and light trucks, is now available from 4WD World.
The Superwinch Winch2Go is a 4000lb (1815KG) portable electric winch designed to be used for 4WD vehicle recovery.
