Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China valve spring manufacturer and distributor of valves, hoses, tubes and pipes. Our oem valve springs are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

Heavy-duty frame and screw for rigidity. Two jaw sizes. For Briggs and Stratton, Clinton, Harley-Davidson, etc. Skin-packed. Shipping weight: 1 lb. Small engine valve spring compressor is used for springs 3/4" to 1-1/16". Made of highest quality spring wire and precision wound to close specifications. Allows for the use of higher RPM and more aggressive cam profiles without the loss of valve control. Some kits include additional keepers (locks, cotters) and spring retainers. We can manufactory any customer spec. Of valve springs, use higest quality Japan swosc-v wire material. Tufftriding/sub-zero treatment process increase life time, sample or drawing are welcome, best price with best quality. Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances.

When valve speed increases by high rotation-ization of engine, 'Jamping' may occur by the factory valve springs. Moreover, since inherent pitch is low, 'Surging' may occur in a high rotation region. In JUN, the valve spring with which the load optimal at the time of a set and a valve lift is acquired was manufactured. Even when the amount of valve lifts increases by using a high cam, since the adhesion margin is secured enough, the JUN valve springs does not have degradation and its durability is also improving. High Rate valve spring set for the Audi 20v 5-cylinder, recommended when running high lift cams or revving past 7000 rpm consistently to prevent valve-float. Will not bind on lifts up to .550" lift. Will fit OEM retainers or our Ti retainers, includes stiffer inner spring as well, 20 valve-spring-pairs in set. Eibach's ultra-pure, high-tensile-strength steel yields a higher natural frequency for the same spring pressures. This often eliminates the need for damper springs, and the problems they can cause, such as cutting into the spring retainers.
