Meticulously crafted from precision billet aluminum, this valve body upgrade follows the reverse PR\/N123N shift pattern and seamlessly integrates instant trans‑brake control in first gear with a supplementary low‑band apply feature, allowing for exceptionally smooth and repeatable launches. The kit’s inclusion of a “clean neutral” safety position offers secure and reliable neutral holding between runs, essential for staging and shutdown reliability.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003e \u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003eWhat sets this version apart is its built‑in internal dump circuit, specifically designed to manage excessive hydraulic pressure in systems using the larger 1 1\/4″ input shafts. This internal bypass protects the shaft seals and ensures hydraulic stability under extreme launch loads. The package also includes a pump cover assembly with an adjustable pressure regulator, along with all necessary fittings and hoses to support precise pressure control and seamless hydraulic plumbing, delivering a clean, integrated setup ready for high-performance conditions.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003e \u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003eTo install correctly and operate as intended, the kit must be used alongside a Precision P08‑408 or P08‑458 shifter and Coan’s billet aluminum direct drum (\u003ca href=\"..\/i-30503862-billet-7075-aluminum-direct-drum-assembly-w-34-element-sprag.html\"\u003eCOA‑22814\u003c\/a\u003e\/\u003ca href=\"..\/i-30503864-7075-billet-aluminum-direct-drum-assembly-w-super-sprag-5-clutch-intermediate.html\"\u003eCOA‑22815\u003c\/a\u003e), ensuring accurate shift positioning and compatibility with the clean-neutral and low-band functions. When mounted in the stock valve body bolt pattern, it provides racers with a compact, bolt-in high-performance hydraulic system that offers lightning-fast trans-brake response, improved launch consistency, and enhanced protection for critical transmission components, ideal for bracket, heads-up, or high-torque applications.\u003c\/p\u003e","brand":"Suncoast Performance","offers":[{"title":"Default Title","offer_id":48219460796657,"sku":"COA-22027-AL-ID-1.250","price":3268.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1344\/3057\/files\/Billet-Aluminum-Instant-Reaction-Trans-Brake-Kit-w-Internal-Dump-For-1-1-4_-Input-Shaft-Suncoast-Performance-151356034.jpg?v=1779832046","url":"https:\/\/tamelessperformance.com\/products\/suncoast-coa-22027-al-id-1-250-billet-aluminum-instant-reaction-trans-brake-kit-w-internal-dump-for-1-1-4-input-shaft","provider":"TAMELESS PERFORMANCE","version":"1.0","type":"link"}
