2001-2016 Duramax Rocker Arm Spacer Kit ( PDM-07184)
Description
Industrial Injection rocker arm spacer kit for 2001-2016 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L Duramax (LB7, LLY, LBZ, LMM, LML). Replaces the factory springs between the rocker arms with solid spacers — keeps the rocker shafts aligned to OE spec under high-load and high-rpm conditions where the factory springs let the shafts drift.
Factory shaft drift causes irregular valve lift and uneven valve/rocker arm wear. Solid spacers eliminate that movement.
