Well... I use the craftsman jack no issues in Ultra or Sporty. Under a 100 dollars on sale
Craigslist is a great place to pick a J&S, pitbull, craftsman... on the cheap.
^^^^ Everything he said is so. I had a Craftsman red jack for many years. Then I bought a J&S jack off CL for $135.oo and sold the Craftsman for $25.oo to a guy who uses it under his Ultra. There are deals out there.
I have a red craftsman Jack I've been using on a Old Electa glide tour Glide works fine on that heavy old bike.
I'm going to make a adapter up this summer so I can pick up my Lawn mower front end to change the blades. This should work on my Suzuki 4 wheeler the same way to pick up the front or the rear.
