Gave the springs a five since they seem to have made it through yet another sh!t attempt at J&P shipping. Free whatever is not worth the headache and hassle and just sheer disrespect for a persons package. I work hard for my money so to see a days hard labor setting in a box that looks like a two year old packed it kind of sets me off. Needless to say unless I can’t find it anywhere else, I don’t care if it’s $5/$100 more than J&P they’ll get my money not J&P.

I have a OD Green 2012 Sportster with Fairing and Luggage Rack in front like the WW2 Harley's. So little bit more weight. Have been applying brakes and going all the way down. After putting the new Fork Springs the ride was smoother and no more going all the way down. Really easy to install and cut spacer to proper size.
