We expertly machined these bearing carrier bushings to be a perfect fit. They are made of a heavy grade steel, machined inside and out, them zinc plated for corrosion resistance. These bushing look way better than the OEM ones, you can see the quality difference! The size is 1.20" diameter, 1.90" long and has a hole for the stock 7/16" bolt. These are also made right here in the USA. These are located on either side of the rear bearing carrier where the lower a-arm attaches. There are two per side and four total on the machine. These are sold EACH so please order how ever many you need. This replaces Polaris part number 5631142 and 5632291.
