Ultimate is a good suspension if ya can get it. I don't like their shocks though not a fan of rubber boots on them, steel stone guards are much better IMO. All the places in Vic that use to sell & fit them, don't anymore ( due to supply problems, not lack of quality ) they now sell OME, EFS, Iornman ect.
So from a warranty point of view, go for one that's readily available.
