{"product_id":"rocker-arm-kit-40","title":"Rocker Arm Kit","description":"The Brian Crower LS7 Rocker Arm Kit (74107F) is engineered for enthusiasts who prefer a steel-based valve train. These shaft-mounted rocker arms are constructed from high-strength stainless steel, ensuring extreme rigidity and accuracy for optimal engine performance.\n\nCrower has meticulously scrutinized every aspect of this system to enhance moment of inertia and valve control. Designed with ease of installation and maintenance as a priority, this kit allows for quick adjustments when time is critical, making it a preferred choice for competitive applications like dirt late models and marine endurance racing. The stainless steel construction offers superior durability and a longer lifespan compared to aluminum components, especially under sustained high temperatures.\n\nThis kit features a 1.8 rocker ratio and is designed specifically for the LS7 engine. Crower also offers an optional needle bearing roller tip upgrade, which can further reduce friction, potentially increasing horsepower and decreasing wear on valve guides and stems. The lighter tips contribute to better valve control at higher RPMs and can improve valve spring longevity by generating less heat than traditional designs.","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":52687288238392,"sku":"74107F","price":2271.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661666371.jpg?v=1784882279","url":"https:\/\/store.motormia.co\/products\/rocker-arm-kit-40","provider":"MOTORMIA","version":"1.0","type":"link"}
