Product Description
Michigan Motorsports LS7 Rocker Arms with Upgraded Bronze Bushing Trunnion Kit Installed
Fits LS7 Engines Only | Complete Set of 16 LS7 Rocker Arms with Bronze Bushing Trunnion Upgrade & Rocker Arm Bolts
Upgrade the valvetrain in your LS7 with Michigan Motorsports LS7 Rocker Arms with Upgraded Bronze Bushing Trunnion Kit Installed. This complete ready-to-install rocker arm set starts with new OEM GM LS7 rocker arms that are professionally disassembled and upgraded with a premium bronze bushing trunnion kit. The bushing-style trunnion upgrade replaces the weak factory cageless needle bearings and powdered metal trunnions that are known to fail and send metal debris through the engine. Whether your LS7 is stock, heads-and-cam upgraded, naturally aspirated, or built for serious performance, this rocker arm set is a major reliability upgrade designed to improve lubrication, increase load capacity, and protect your engine from one of the most common LS valvetrain failure points.
Key Features & Benefits
- Complete LS7 Rocker Arm Set: Includes 8 LS7 intake rocker arms, 8 LS7 exhaust rocker arms, and 16 rocker arm bolts for a complete LS7 valvetrain service package. Each rocker arm is professionally upgraded and ready to bolt onto compatible LS7 cylinder heads without requiring separate trunnion installation work.
- Bronze Bushing Trunnion Upgrade Installed: The upgraded bronze bushing trunnion kit is already professionally installed, saving time and eliminating the need to press apart and rebuild the rocker arms yourself. This ready-to-install setup is ideal for engine builders, performance shops, and LS7 owners wanting a proven valvetrain reliability upgrade.
- Replaces Weak Factory Needle Bearing Design: Factory LS rocker needle bearings can fail and release loose needle bearings into the engine, creating serious risk to the oiling system and internal components. This upgraded bushing-style design eliminates loose needle bearings and helps protect the engine from catastrophic debris-related damage.
- C932 Bronze Bushing Material with Oil Feed Grooves: The special C932 bushing material is lubricated through oil grooves at two locations on the trunnion, continuously feeding oil to the bushing surface. This design supports excellent lubrication, reduced wear, and long service life in demanding LS7 street, race, and high-RPM applications.
- Built for High-Load LS7 Valvetrain Demands: The greater surface area of the bushed trunnion supports dramatically higher load capacity than a needle bearing trunnion, making this upgrade highly recommended for aggressive heads-and-cam combinations, performance LS7 builds, and engines where rocker arm reliability is critical.
