SDPC SD1370 - Trunnion Kit For LS and Gen V LT

The factory GM rocker arm, while lightweight, can be a weak point when subjected to the demands of performance driving. When paired with higher lift camshafts and increased spring rates, the stock caged needle bearings often fail, leading to catastrophic engine damage as the needles migrate through the engine. Our Trunnion Kit offers a permanent and necessary upgrade for your valvetrain: Premium Proprietary Bushings: We replace the failure-prone stock pieces with a new high-strength trunnion utilizing a premium proprietary bushing. This design dramatically increases strength and provides added security for performance applications. Superior Lubrication: Dedicated oil fill channels in two positions on the new trunnion ensure a constant supply of oil, guaranteeing proper lubrication and extending component life. Prevent Catastrophic Failure: Say goodbye to catastrophic engine failure caused by the loss of a stock rocker arm needle bearing. This kit is engineered to provide reliable performance across the best GM V8 engines, making it the essential valvetrain upgrade for: Gen 3 LS Engines (e.g., LS1, LS6, etc.) Gen 4 LS Engines (e.g., LS2, LS3, LSA, LS7, LS9, etc.) Gen V LT Engines (e.g., LT1, LT4, L83, L86, LV1/LV3, etc.)
