{"product_id":"ls-1-72-1-roller-rocker-arm-kit","title":"LS 1.72:1 Roller Rocker Arm Kit","description":"These rocker arms are constructed from durable steel and feature integrated roller tips. This design offers increased strength over factory rockers while simultaneously reducing friction and wear at the valve tip.\n\nEngineered as a true bolt-on solution, these rockers utilize factory rocker arm pedestals for straightforward installation. They strike an ideal balance between robustness and a lightweight valvetrain design, which helps preserve RPM capability and stability. Each set includes the TSP trunnion upgrade kit, which features upgraded bearings for smoother operation, improved oiling, and a longer service life compared to standard needle bearings.\n\nThe 1.72:1 ratio provides a performance upgrade by increasing valve lift and airflow, leading to enhanced overall engine performance.\n\nImportant Installation Notes: Pushrod length will need to be changed when installing these rocker arms. A recommended pushrod length is approximately .175\" shorter than your current setup. Always verify correct pushrod length during installation to ensure proper valvetrain geometry.","brand":"Texes","offers":[{"title":"Default Title","offer_id":52689411998008,"sku":"25-TSP172RR-CATH","price":705.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687712216.jpg?v=1784906380","url":"https:\/\/store.motormia.co\/products\/ls-1-72-1-roller-rocker-arm-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
