The Industrial Injection PDM-07184 Rocker Arm Spacer Kit can help improve the reliability of the valvetrain in your 2001-2016 GM 6.6L Duramax. This rock arm spacer kit removes the springs in between the rockers that are design to keep the rockers aligned under high load or high RPMs. The stock springs permit the rocker arm shafts to shift, causing irregular wear on the valves and rocker arms leading to irregular wear. This spacer kit is engineered to prevent this shifting which allows your engine to run more smoothly and reliably under stressful conditions.

• Increased Reliability
• Properly Align Rocker Arms
• Prevent Irregular Valve & Rocker Arm Wear
