20 Ton 6" Extension

Safe Jack

  • $ 11300

PN: 37312
UPC: 854185005578

The 6-inch Bottle Jack Extension adds 6 inches of height to the available stroke of a bottle jack. Don't risk your health and safety piling up unstable wood or rock under the jack; start lifting safer! Multiple Extensions can be stacked to increase the height of the hydraulic cylinder (ram.) All of our made-in-the-USA Extensions and Lift Pads feature a solid steel shaft.

Safe Jack utilizes the Extension Screw Collar to create a secure engagement for the Extensions and Lift Pads, as well as to maximize the available stroke to an additional 1.5 inches. These premade Extension Screw Collars are measured specifically for the bottle jack brands we carry. If you have your own bottle jack you wish to use instead, you may need to purchase a Custom Extension Screw Collar. If you opt out of purchasing a Custom Extension Screw Collar altogether, the adapters may still work, but you will not achieve the additional 1.5 inches of stroke. The 20-ton adapters will fit over a bottle jack saddle diameter of 1.75 inches - 2.25 inches (44.45 mm - 57.15 mm.) If the hydraulic cylinder (ram) is significantly smaller than this, we advise against using the adapters without an Extension Screw Collar, as the point of engagement will be unstable.

    Built Tough

    The safe jack extensions (6 inch and 3 inch), as well as the Axle/frame adaptor are all built with precision and might hefty. They fit my 20 ton bottle jack well, and make for a much safer way to jack up my Overland F150. The powder coating is very durable and looks great too. Thank you for an excellent product, that gives greater peace of mind when having to raise my vehicle and know that it is done safely. Thank you for your prompt service, and great customer service too. I highly recommend these products. Andy Gillespie
