These machined tubes sleeve the factory Polaris RZR rear lower A-arm tubes and strengthen it at a point where the arm receives a lot of force. Breaking the lower spindle bolt is a common problem with the way the lower coilover mount is on the back side of the arm. This causes the a-arm to want to twist with hard impacts where it can shear off the bolt head. Our bolt in sleeve strengthens the a-arm where it needs it the most and spreads the forces from the coilover more evenly across the a-arm. This should also add to the life of the outer spindle bushing. Another nice feature we built in is CNC machined end pieces with rubber O-rings that close up the open tubes and keep them from getting packed with mud and dirt. Tubes and machined end pieces have a Zinc Chromate finish and come with stainless machine screws. To purchase visit ATR Store!
