Do the J & S jack it is the best

 

I think the best bet would be to get a measurement of the distance inside the nubs and compare that to the width of the frame on your bike. I know that on my J&S I have never measured it but have probably 1" or so of the lift arms sticking out on each side of the frame rails on both my WG and RGU.

My guess is they would not be in the way as they are on the end of the lift arms, if your frame is so wide that it comes that close to the edge of the lift arms on anybike you are cutting it to close IMHO

 

Don't know if you can order from J & P Cycles but they have the same lift for $341
