or you can be like me and stack tons of washers on top of each other did it to my dads sled, did it to a friends on wednesday, and am doing it to another friends sled tonight. cheap and a lot stronger than you think.
I have used Ole's on several sleds and have been very happy with them. Have also used Roxx and have been equally as happy. Going to depend on what style you are looking for.
did my 3rd sled tonight by stacking washers. 12 washers = 1". did a 2" on my dads 99 xcsp 700, 2" on a buddy's 01 zr 600, and a 3" on a buddy's 03 zl 550... Under $5 per riser and a lot stronger than you think...
