I have a yellow jack for my Superglide my son in law seen it and liked it . He has a 04 Wideglide, so I'm getting him a yellow pro for Christmas. My ? is does he need the blocks on a Wideglide or will it fit on the jack without them. Thanks

 

He'll need them...some guys here use a 2x4 though.

 

With the yellow jack you can get by without one if you only use the front riser pad. The rear can be balanced between the kickstand and the frame, done it many times.

 

I would get them...inexpensive insurance.
