Since race engines these days require more power at higher RPM use, these engines now experience more extreme heat conditions. These conditions will increase the deterioration rate on these valve train related components. The Phosphor Bronze material has exceptionally lower friction and the best possible clearances can be maintained, which will reduce the stress on the valve train assembly, prevent seizures and cracking under high stress loads.\u003c\/p\u003e\r\n\u003cp align=\"justify\"\u003eWhen installing Tomei Type A valve springs in an RB26 and performing a three angle valve job, the stock spring load spec of 24kg is decreased to less than 20kg. By installing the Tomei Valve Spring Seats, the spring load can be brought back to tolerance to the 24kg range, enabling the engine to rev freely once again.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003ch3\u003eFeatures\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003ePhosphor Bronze(Cn-Sn-P alloy)\u003c\/li\u003e\r\n\u003cli\u003eFit for high horsepower applications\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch3\u003eBenefits\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eSuperior heat transferring ability\u003c\/li\u003e\r\n\u003cli\u003eLow friction coefficient\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cdiv id=\"newdescrLC\"\u003e\r\n\u003ch3\u003eApplications\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e1989-1990 Nissan Silvia \/ 180SX\u003c\/li\u003e\r\n\u003cli\u003eEngines Covered: CA18DE(T)\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch3\u003eWhat's In The Box?\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e1 - Set of Valve Guides\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch3\u003eReferences\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003ca href=\"https:\/\/www.tomeiusa.com\/manuals\/TA309.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"clear\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52024866341156,"sku":"TOM TA309A-NS11A","price":336.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0671\/6801\/0532\/files\/valve-guide-set-vr38dett.jpg?v=1771487279","url":"https:\/\/autohousesupply.com\/products\/tomei-valve-guide-set-ca18det-ta309a-ns11a","provider":"AutoHouseSupply","version":"1.0","type":"link"}
