The 8-inch Bottle Jack Extension adds a whopping 8 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 12-ton adapters will fit over a bottle jack saddle diameter of 1.25 inches - 1.75 inches (31.75 mm - 44.45 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.

    Fixes flats and old tires like a charm
    Style: 1 gal
    This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.

    slime is and has always been amazing for bike tires and other small pneumatic tires
    Style: 1 gal
    this is a great value, I have been using slime in my tubes of my bikes and a small inflatable pneumatic tires for probably 30 years, and I can say slime has only improved, and it works fantastic, this is a very good way to save money, and it works great on goat heads and several other ways your tires can get punctured, I still always recommend carrying a small air compressor or pump, but for the price point you just cannot beat slime, every bike shop should always carry this.

    They need to find a better way to ship it
    Style: 1 gal
    What was left in the bottle worked great. However, the cap was off of the jug when I opened the package. Ididn't have enough for the other tires.
