With their 100a durometer rating these Doh Doh bushings are the hardest that Shorty's make. Good for going big, these bushings are firm enough to absorb the impact of those 12 stair landings and feature great snap back to help you straighten out on impact. Also great for those heavier skaters out there.
they're great but beware in the cold weather they might freeze if they do DONT PLACE IN MIRCOWAVE THEY WILL EXPLODE but other than that they're pretty good washers needs to be big so go to daddies and they have some for $5 or less and free shipping
I have some Koston hollows and replaced the bushings with these, and I gotta say that I was pleasantly surprised, I tightened them up a little to give me a medium feel, no speed wobbles unlike the Independent mediums that I use to have. I love them, excellent bushings, takes some time to break in though.
Bushings were not flexible. They seemed dried out or something and started cracking and deforming when I put them on trucks and tightened a little. I took them back off immediately. First time I ever had a problem with the Shorty's bushings. Probably bought 7 or 8 sets before. Maybe really old stock?
