Constructed from aerospace-grade alloy and enhanced by shot peening to improve fatigue resistance, this shaft introduces a unique ringless design with mid-shaft bushing journals. This configuration enables the integration of cooling circuits while significantly reducing shaft flex under extreme loads.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cspan class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\"\u003eAs a drop-in component, the COA‑12805 fits seamlessly into Powerglide cases with no need for housing or pump machining, provided the appropriate pump assembly (e.g., COA‑12814\/12815\/12816A\/B) is used. Whether you're building a high-horsepower street cruiser, a serious drag racer, or a bracket competitor, this shaft delivers exceptional torque handling, improved longevity, and reliability in demanding environments\u003c\/span\u003e.\u003c\/p\u003e","brand":"Suncoast Performance","offers":[{"title":"Default Title","offer_id":48219452768497,"sku":"COA-12805","price":1135.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1344\/3057\/files\/Ringless-Super-Shaft_-Aerospace-Alloy-Input-Shaft_-12-7-8_-Shot-Peened-Turbo-Splines-Suncoast-Performance-151323338.jpg?v=1779831730","url":"https:\/\/tamelessperformance.com\/products\/suncoast-coa-12805-ringless-super-shaft-aerospace-alloy-input-shaft-12-7-8-shot-peened-turbo-splines","provider":"TAMELESS PERFORMANCE","version":"1.0","type":"link"}
