These idler pullies are made from billet 6061 aluminum and use two SKF 6203 bearings for durability. The rear spacer is included, and these are designed to work with a stock bolt. They are available in two diameters: 100mm and 76mm. Please note the 100mm have been redesigned to accommodate 12-rib LSA systems and will have an excess of unused area towards the front on 8-rib systems. The 76mm is not intended for LSA drive systems.
