i ordered, and then returned the skyking product. I did not like the fact that the bolt shank diameter was significantly smaller in diameter than the frame hole that it was supposed to fit within. i've never seen a stress point engineered as such and doubt if it would muster any SAE approval. Skyking simply gave me a blah blah about how the strength of the bolt should prevent any problem...sorry but it looks like a 'one size fits all' solution in which case the with the Sprint ST the bolt shank size is smaller than the mate and stock fit. i returned for refund..but unfortunately did not have it insured, or certified and Skyking claims not receipt of the package so i'm screwed out of the $100.00, yup may have been "lost in the mail' but i've never had that happen before..but I've learned my lesson to always insure or use some form of certified mail...duh
went with the LSL product
