Roadsafe Bottle Jack Ram Extension Kit

What are Ram Extensions and why do I need them?

Four wheel drivers with lifted vehicles are often faced with quite a significant dilemma when out in the bush with a flat… their factory bottle jack is no longer effective!  They have lifted their vehicles 50-100mm and the bottle jack ram does not extend high enough to get the tyre off the ground.

To get around this the current options are to:

• Get a lump of wood or cribbing blocks to place under the bottle jack (dangerous because instability could result in collapse)
• Purchase & carry a new bottle jack/trolley jack with a ram length extendable to suit their lift (expensive & big/heavy to carry)
• Use a High Lift jack or similar (unstable at height, sometimes difficult to use, not everyone has one)

Roadsafe  ‘Bottle Jack Extensions & associated Bottle Jack accessories’ are aimed at making the process of jacking up vehicles a much safer and more secure one.

How to the Ram Extensions work?

Roadsafe Bottle Jack Extensions are sized to slip over the ram of the standard bottle jack and basically act as a ram extension, adding length to the ram so the jack can sit firmly on the ground while the load is lifted. The parts slot snugly together, which makes the jacking option much safer and less likely to tip and become unstable.

The standard extensions have been designed with 35.5mm ID so suit for ram diameters of between 28-35mm (6 ton bottle jack typically have a 1.25” (31.75mm) ram diameter).

What size are the Extensions and how much additional height can I expect?

Extensions have been designed allowing for 75mm (3”), 150mm (6”) & 225-305mm adjustable (up to 12”). The extensions have been designed to slot together snugly, so you can interchange the pieces to get the height & configuration required. Using all three extensions together will give 530mm (20”) of extension.  The key is, however, to keep the jacking process a safe one.  Always refer back to safe jacking practices.
