{"product_id":"1-3-billet-roller-rev-rockers","title":"1.3 Billet Roller Rev Rockers","description":"The EC 1.3 Billet Roller Rev Rockers are a performance upgrade designed to enhance the capabilities of Non-Hemi Honda, Clone, Tillotson, and Predator Cylinder Heads. These rockers offer improved valve lift and duration due to their 1.3:1 ratio, which can significantly boost engine performance by optimizing airflow into the combustion chamber, especially at higher RPMs.\n\nConstructed from aircraft-grade billet aluminum, these rocker arms are both lightweight and strong, helping to reduce valve train harmonics and increase stability. They feature a hardened, oversized roller tip that provides increased clearance and reduces wear on valve tips, making them suitable for high-lift camshaft setups. The integration of needle bearings at the pivot point is a key feature, significantly reducing friction and wear compared to traditional bushing-style rockers, thereby preventing seizing and enhancing overall durability. Proper lubrication with products like Maxima Racing Oil Assembly Lube is recommended during installation.\n\nIt is crucial for users to verify their engine type and cylinder head model to ensure proper fitment. The improved valve lift and acceleration may also necessitate adjustments to spring pressure, so users should consult their cam's specifications.","brand":"EC Carburetors","offers":[{"title":"Default Title","offer_id":52687887106360,"sku":"1505RR","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663169997.jpg?v=1784887075","url":"https:\/\/store.motormia.co\/products\/1-3-billet-roller-rev-rockers","provider":"MOTORMIA","version":"1.0","type":"link"}
