I am getting a 1991 K100LT from a friend and it has a lowered Wilbur or Works rear shock, he was not sure but I am 6'3" so that will not work. Any opinions on the Progressive 412? I am not one that plays with suspension adjustments so I just need a shock that will get me back to stock ride height. He did not think the bike was factory lowered and remembered seeing the stock shock but it appears his mom tossed it. Thanks, as you can tell I just need a cheap replacement. Yes, I am cheap.
