This is a replacement belt tensioner damper for your LSJ powered vehicle. This damper connects the belt tensioner that holds the pulley to the block and is what actuates as you loosen belt tension with the tensioner.

If you are experiencing belt slip or rattling of your tensioner bracket/pulley, this may be the culprit. If you are doing our ZZP adjustable tensioner, this is a great replacement to do at the same time. 

Fits: 2004-2007 Saturn Ion Redline 2.0L, 2005-2007 Chevrolet Cobalt SS 2.0L
