I have a 2014 550 and am going with kendra bear claw hrt 26/9 on front and may or may not need spacers. I can’t find anything in the search that is specific to my 550/ I did read somewhere that I may only need like 1/4" or 1/2" spacers. What sizes tdo they come in and if you put spacers on the front would you put them on the rear as well to keep the rig symectrical.
