To disembark jeeps in amphibious landings, in 1943 a deep water fording kit for the jeep was produced. This enabled jeeps to be driven off landing craft like the LCM (Landing Craft Mechanized), wading into relatively deep water, without flooding the engine or short-circuiting the electrical system. After several interim kits were issued, the U.S. Army standardized the universal WV-6 kit (later G9-5700769) which served all WWII ton to 2ton trucks. The kit contained flexible hoses for both the exhaust and the air intake, as well as proper waterproofing equipment. Westinghouse developed a T1 air compressor, to be used in conjunction with special tires, to deflate the tires off-road, in soft mud or snow, and be able to pressurize them again after. It could be fitted under a maintenance work order, from October 1944. There was even a small capstan winch field kit made for the jeep, driven off the motor, for self-extracting, or pulling other jeeps trapped in mud or snow. The winch was very small, and made hand-cranking of the jeep impossible. The latter two gadgets remained very rare.
