6 Ton Extension Screw Collar

Safe Jack

  • $ 1800

My bottle jack does NOT fit the dimensions.

PN: 37110
UPC: 854185005387

Adds 1.5 inches of stroke to a 6 ton bottle jack by extending the screw without increasing the starting height when used with a jack pad or jack extension. The size is perfect for most 6 ton bottle jacks with rams ranging from 1.25 -- 1.3 inches in diameter and screw diameters up to .955 inches

Extension screw collars provide the proper fit for jack extensions and jack pads but they also give the operator 100% of the usable stroke of the jack. The collars are easy to install taking only a few seconds and they can be removed just as easily.

These are standard equipment for our bottle jack recovery kits and should be used anytime extensions or jack pads are used for proper fit and to maximize the useful stroke of the jack.

6 Ton Accessories not for use on Toyota OEM  or Telescoping Jacks.

High Quality and good service

I purchased the 3 piece starter kit for my 4-ton Harbor Freight bottle jack and Jeep Wrangler JK. Since my jack had a smaller diameter ram, I also purchased a custom sized extension screw collar. I was very pleased with the communication from the company and prompt delivery of the items. I have not had a chance to use these items yet but the build quality looks amazing! Given the height of the jack, and plates, I doubt I'll be able to use this combination of equipment to deal with a flat tire so I'll still plan on using the scissor jack for that. However, for all other lifting needs, this combination of equipment will be an extreme improvement over the stock scissor jack. For my jack, I ordered the following custom extension screw collar: Bottle Jack Saddle: 1 Bottle Jack Screw: 0.625 Jack Brand: Harbor Freight Jack Tonnage: 4 Jack Part Number: 69472

Just what I needed

This worked for me, my truck has a level kit on the front end and the jack that came with the truck would not lift it high enough to get the front tires off the ground. When I used the Jack extension on a bottle jack it allowed me to remove the front tires. I am very happy with this product.

Good fit

Extension screw collar was good fit and allowed nearly no slop between jack and attachments. Have used it when jacking family CR-V and Silverado, with complete confidence.

Collars make the difference

Now my offbrand jacks work with the safety jack accessories and I now feel secure about using the equipment. Without the collars, the fit was unacceptable, and now perfect!
