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\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eStill since the product will be used for extreme conditions, it will still require additional regular maintenance and periodical checks.

However, with the engine used by high rotation and high load, the cooling performance of a valve sheet becomes very important further, and it is greatly concerned with an engine output. When engine is high rotation and high load, it is impossible to achieve high output from the engine if cooling performance of the cylinder is low and knock limit does not become high, since the temperature of the circumference of a cylinder head rises unusually. In racing engine that temperature needed to be carefully controlled, how much you can cool the circumference of the sheet ring is the important issue, and the technique of using high heat conduction metal, such as copper for a sheet ring, has been taken. Copper has one of the highest thermal conductivities through all metal that enables receiving heat from cylinder and cool it down quickly by transmit the heat to the cylinder head. (Degree of heat conduction: 1.silver, 2.copper, 3.gold, 4.aluminium, ... 10. cast iron - STD). We select beryllium copper alloy (BeCu) that can secure mechanical intensity most in the copper alloy, which has ideal fatigue resistance and wear resistance while securing a preeminent cylinder cooling performance. We named it \"bery-ring\" and applied to the high performance turbo charged engine. of market share in the world with beryllium copper so that we can offer this super-high grade material beryllium in affordable price. \u003cbr\u003e\u003cbr\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/0040\/2689\/2361\/files\/eP101_beryring_large.gif?v=1536943314\" alt=\"\"\u003e\u003cbr\u003e\u003c\/span\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":13373594992713,"sku":"TA310A-NS05A","price":1080.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0040\/2689\/2361\/files\/berylium-valve-seat-ring-set-rb26dett.jpg?v=1741652113"},{"product_id":"brian-crower-billet-valve-keepers-locks-for-nissan-rb26dett","title":"Brian Crower Billet Valve Keepers \/ Locks for Nissan RB26DETT","description":"\u003cp\u003e\u003cstrong\u003eBrian Crower Billet Valve Keepers \/ Locks for Nissan RB26DETT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e6mm stem diameter, 6° billet performance valve stem keepers or locks are designed to fit BC and OEM retainers.
