{"product_id":"heavy-duty-trunnion-kit","title":"Heavy Duty Trunnion Kit","description":"The Summit Racing™ LS Series retrofit trunnion kits are engineered as a robust solution for LS engines that have been modified with higher lift camshafts and heavier valve springs. These kits provide the heaviest duty trunnions available for stock-style rocker arms, ensuring enhanced durability and performance under demanding conditions.\n\nConstructed from micro-polished, hardened steel, these trunnions are built to withstand significant stress. They incorporate C932 bronze bushings for smooth operation and longevity. The design is specifically intended for use with stock-style rocker arms and can accommodate both Rectangle and Cathedral Port cylinder heads, making them suitable for Gen. 3 and 4 Chevy LS engines. The set includes 16 trunnions, enough for a complete engine, and is designed to be compatible with OEM rocker arm bolts.\n\nFor proper installation, Summit Racing also offers specialized trunnion installation tools (SUM-141560-IK), sold separately.","brand":"Summit Racing","offers":[{"title":"Default Title","offer_id":52663900930360,"sku":"SUM-141560","price":179.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687718994.jpg?v=1784330634","url":"https:\/\/store.motormia.co\/products\/heavy-duty-trunnion-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
