The Lone Star Racing RZR 170 swingarm is a heavy duty replacement for the weak stock swingarm. It is made from 1 1/4" 4130 chromoly tubing and has heavy duty 3/4" heim joints to mount it to the frame. It also comes with heavy duty 10mm chain adjusters. The swingarm is stock geometry so it will bolt directly onto your RZR 170.
