Fit OK on the Speedway low friction ball joints
Using these on K772 Speedway Low Friction ball joints on a tubular control arms with the welded in ball joint sockets. Not much seems to fit these, had some luck with the urethane ones, but gave these a shot. these seem to work OK, not perfectly sealed but fitment is as good as I can expect for the application. These are nice and low profile, so they don't get crunched up as bad as the other more stock looking ones (Part # 91034006).

Using with the 91721139 1" extended ball joint
Will work with the 91721139 1" extended ball joint but had to silicone around the bottom and use wire to tie it in place. A little awkward to do but once in place should do the trick. Not sure I would recommend it or not, if you're up to the challenge...giver!

I like the fact that it is very flexible in the center for zero tolerance ball joints but I wish it came in different sizes. They are to big for QA-1 Ball joints had to poke two holes in the bottom of the boot and zip tie around joint housing to make it tight around the joint housing - it will work fine just beware that they are bigger around the bottom than a normal joint boot.
I would buy again

Fit the tall adjustable balljoints well. I felt the balljoints should have come with dust boots.
