Our beehive spring uses an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. What this means to you is our spring has the highest level of spring load retention while still maintaining good fatigue threw out the life of the spring. Only the best materials go into the GSC Power-Division Beehive valve spring. Each batch is scrutinized for tensile strength properties, ductility, inclusion content, and fatigue toughness.\u003cbr\u003e\u003cbr\u003eThe beehive valve spring shape has become the buzz lately. Some have enquired as to the benefits of a beehive spring vs the dual springs that are sold by others. While some might find that the beehive spring design is new it has been used commonly in many OE engines as well as in all of the NASCAR and F1 engines of today. Why? The beehive shape is more stable than standard single or dual cylindrical springs. The beehive design which incorporates an ovate wire is more than capable of the performance demands that were previously only matched by a Dual Springs. With the smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control.  So beehive valve springs, with there lighter weight retainers allow for engine's to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs of yesteryear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBeehive Spring Benefits:\u003c\/strong\u003e\u003c\/p\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\n\u003cul\u003e\n\u003cli\u003eRev faster\u003c\/li\u003e\n\u003cli\u003eLighter components\u003c\/li\u003e\n\u003cli\u003eMore durable design\u003c\/li\u003e\n\u003cli\u003eLess stress on valvetrain components\u003c\/li\u003e\n\u003cli\u003eLower spring frequency for more precise valve control.\u003c\/li\u003e\n\u003cli\u003eMore valve control equals more aggressive cam profiles\u003c\/li\u003e\n\u003cli\u003eNano Peened for faster break in and less stressed springs\u003c\/li\u003e\n\u003cli\u003eAll of these items help to return more power for you to enjoy!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe GSC 5039 Beehive spring is a factory replacement and will use your stock OEM retainer and valve seat to ensure an easy and inexpensive upgrade for your upgraded camshafts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5039 Beehive spring pressure:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e1.56\"=86 lbs \/ .450\"=220lbs \/ .625\"= Coil bind.\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e5039 Beehive Rev and Boost range (using an S2 profile camshaft set)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMax RPM: 8200\u003c\/li\u003e\n\u003cli\u003eMax boost: 25 psi\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e5039 Beehive Max lift\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eDo to stock retainer max lift is 11.2mm at the valve or .259\" cam lobe lift.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c!--\/ Vehicle Applications --\u003e\u003cbr\u003e\u003cbr\u003e\u003ch3\u003eVehicle Fitments:\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1993 -
