The bolt on A-Arms offered by us deserve a close look to see why they are such a good buy. Our YFZ450 A-arms are +0" forward and +2" wider. Keeping with the performance end they are fabricated from 4130 alloy. The ball joint bosses are threaded on both top and bottom arms for strength and no possibilities of loosing the ball joint due to a loose nut. The ball joints are the new Ricky Stator full ball joints that were built for us for a-arms not tie rod ends from VWs or other. The Delrin® pivot bushings are pressed into the Arms and then precision reamed for the bearing boss. The tie-rods are 4130 alloy tubing to accept the stock tie-rod ends. The Arms are finished with two layers of powdercoating-one silver colored and one clear for durability. We are convinced they are the best available regardless of price. Remember- anyone can build Arms that go up and down. We chose to build them geometrically correct. The shock tab is in the stock location so you can still use your after-market shocks with only a 'tune-up' for the extra length.
