This is a brand new upper "even" a-arm. This will work on the right or left side of your kart. You can tell if you have an "even" front end by looking at the ball joints on one side of the kart. If the ball joints are directly on top of each other, then it is an "even" front end. This a-arm may differ from early Spiderbox models, these do not use a bronze bushing and sleeve in the a-arms. The a-arms & center box are drilled to utilize only a 5/8" bolt.
These work with this ball joint sku # 06340 only! Will not work with aftermarket ball joint from Buggy Depot!
Allow 1-2 additional days for order processing, because these a-arms are made to order.
