At high RPM, aggressive driving, or during over-rev situations, the SR rocker arm can deflect or jump, which may lead to serious engine damage. The Tomei RAS helps control rocker movement by stabilizing the lash adjuster side of the rocker arm, reducing the risk of rocker arm failure during high-load operation.\n\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesigned for SR20DE(T)\u003c\/strong\u003e valvetrain stability at high RPM.\u003c\/li\u003e\n  \u003cli\u003eControls rocker arm deflection to help prevent rocker arm dislodging.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eSet includes intake and exhaust stoppers.\u003c\/strong\u003e\u003c\/li\u003e\n  \u003cli\u003eSPCC steel construction with chromate coating.\u003c\/li\u003e\n  \u003cli\u003eSpacer hardware included.\u003c\/li\u003e\n  \u003cli\u003eWeight: approx. 170g.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Upgrade?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSR engines can experience rocker arm jump during sustained high RPM or missed shifts.\u003c\/li\u003e\n  \u003cli\u003eHelps protect the engine from valvetrain damage in performance driving conditions.\u003c\/li\u003e\n  \u003cli\u003eRecommended for modified engines or builds running higher RPM limits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e Nissan SR20DE \/ SR20DET\u003c\/li\u003e\n  \u003cli\u003eCommon Applications: Silvia (PS13\/S14\/S15), 180SX, 240SX swaps\u003c\/li\u003e\n  \u003cli\u003eNote: Head cover modification may be required on some models.\u003c\/li\u003e\n  \u003cli\u003eNot compatible with VVL setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e TA311A-NS08A\u003c\/p\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":48807515652348,"sku":"TA311A-NS08A","price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1128\/7276\/files\/TA311A-NS08A_7c06da20-3cd2-43a1-8dc8-b153e0b8bfdb.jpg?v=1772033196","url":"https:\/\/jdcustomsusa.com\/products\/tomei-rocker-arm-stopper-sr20det","provider":"JD Customs U.S.A","version":"1.0","type":"link"}
