GM Rocker Arm Spacer Kit For 01-16 Duramax Industrial Injection

The Duramax Rocker Spacer Kit was designed to eliminate the factory springs in between the rockers to keep the rockers properly aligned to OE spec under high load and high rpm conditions.

The factory springs allow the rocker arm shafts to move around which can cause improper valve lift and irregular wear on the valves and rocker arms.

Our high performance rocker arm spacers prevent this from happening and allow your engine to operate more efficiently and more reliably under high stress conditions.

This kit is deigned to work with 2001-2004 LB7, 2004.5-2005 LLY, 2006-2007 LBZ, 2007.5-2010 LMM, 2011-2016 LML Duramax engines.
