This piece will replace your stock LSJ tensioner arm and it has three different holes for the tensioner pulley to be bolted to. It will allow you to use the stock belt down to a 2.6" pulley while retaining the proper belt tension. This is an upgrade from LSJ oversized tensioner pulley and GM stage 2 belt.

If you're experiencing excessive belt slip or noise from the tensioner area that isn't related to the stock pulley you may need to replace your tensioner damper, we stock them here.
