I put set on mine and never looked back.
The sled handles better hill climbing,easier to throw around.Seem to not trench as much...On the trail it's alot more tippy,but it's takes the bumps better.
The brackets take away the full floating and makes it soild.
Which I like better..
A couple of weeks ago I was talking to a guy at Renshaw and he swore by it. He said it changed the swing arm geometry and improved the ride. He mentioned that it compensated for the rear suspension spring sag that occurs after a few years on the Mountain Cats ( I am not sure how it does that - I never noticed any change in my springs)
well i put these on and they seem to do just what they claimed they would ,the handling ,suspension was smooother and i can sure lay it over easeirer i love them ,(TO BAD THEY ONLY MAKE THEM FOR CAT SO THE REST OF YOU COULD EXPERIANCE IT TO)
