{"product_id":"ls3-shaft-rocker-kit-v2","title":"LS3 Shaft Rocker Kit V2","description":"The BTR LS3 Shaft Rocker Kit V2 is engineered to address the inherent valve train deflection issues in stock Chevrolet Gen III-IV-cylinder heads. This system, typically found in more expensive setups, utilizes a billet steel stand with multiple shafts and bearings per cylinder head to minimize deflection, leading to enhanced performance and increased durability. The shafts are constructed from genuine 52100 bearing steel, and each pair of rockers is secured with five fasteners to the stand, a significant upgrade from the traditional single-bolt configuration.\n\nThis V2 version of the kit features a shim design for easier assembly and improved durability over previous snap-ring designs. It is professionally assembled with new OEM GM rocker arm bodies and is ready to bolt onto compatible engines. The kit can reuse stock GM rocker arm bolts, or new BTR rocker arm bolts can be included. The BTR LS3 Shaft Rocker Kit is designed for 2007-2015 Rectangle Port LS Heads (6.0L and 6.2L engines including LS3, L99, LSA, LS9, L92, L9H, L94, L96, L76, L77) and is compatible with OEM Casting #'s 821, 823, and 5364. However, it will not fit Trick Flow or AFR heads, and users should verify fitment with other aftermarket heads.","brand":"BTR","offers":[{"title":"Default Title","offer_id":52687300493624,"sku":"BTR LS3 SHAFT ROCKER KIT","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661666551.jpg?v=1784882365","url":"https:\/\/store.motormia.co\/products\/ls3-shaft-rocker-kit-v2","provider":"MOTORMIA","version":"1.0","type":"link"}
