How To Use An Exhaust Jack For Four-Wheel Drive Recovery
A lesson in four-wheel drive self-recovery using an exhaust jack by Glynn Williams
Tired of getting your four-wheel drive bogged or caught up on rocks and having to dig yourself out or fill in holes to improve your traction? It can be physically exhausting and it certainly takes the pleasure out of your four-wheel drive experience spending most of the time getting bogged or caught up. Though there are many techniques that Perth operated four-wheel drive training school Western Wilderness 4WD & Survival Training teach as part of their Perth four-wheel drive trainer courses, the use of the popular exhaust jack is a welcome option as an addition to any four-wheel drive recovery kit for quick, safe and effective self-recovery.
An exhaust jack uses your vehicle’s exhaust or an air compressor to lift your vehicle safely by inflating. Quickly and easily lift vehicles up to 4-tonnes. In seconds you can lift your vehicle out of bogs or ruts using the exhaust air jack.
An exhaust jack recovery kit will generally contain, a puncture repair kit in case the exhaust jack is pierced, a pair of work gloves to keep your hands clean as well as protected, protective mats to protect your jack from sharp under car body projections or sharp rocks and sticks on the surface where the exhaust jack will be placed, a carry bag to store the jack and accessories in, an extension hose, an exhaust hose and the exhaust jack itself.
A good quality exhaust jack is designed with several layers for operational strength. Exhaust jacks are a good alternative to a high-lift jack to minimise the risks associated with vehicle damage that can occur with high-lift jacks. An exhaust Jack is suitable for use in varying surface conditions; sand, mud, soft, sloping ground or snow.
