Id like to post a review of Houser's Great customer service. When we tore down my yfz, we realized the upper a arms had some play in them. they had 5 "washers" in place for spacers. I contacted Rob at houser racing by email to ask him what the deal was and what was actually supposed to go there. He informed of what model a arms we had, and what was actually supposed to go in place. I also told him that we had received the wrong sleeves to replace the bearings. He told us we had the caster adjustment a arms, and that there are actually only 3 spacers per side. He told us a price for the real spacers and correct sleeves and even gave us $30 credit if we sent in the wrong sleeves. So were working on getting this all sorted out and ordered with Rob's help. Thank You Houser Racing for the great customer service!
