4G63 Beehive Valve Springs with Titanium Retainers by GSC Power-Division

GSC Power-Division Beehive springs feature some of the most impressive manufacturing techniques in the industry. 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.

The 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.

The GSC 5041 Includes a Beehive valve spring set, and Grade 5 Titanium retainers You will use the OEM spring seat. This kit is capable of 11000+ RPMS, with as much as 12.1mm lift cams (net valve lift max due to seal to bottom retainer contact). This is a must have for anyone pushing the limits. If you have had problems with valve float or throwing rocker arms this is the spring set that will cure your problems for good.

Great quality

Got the job done

1G DSM GSC Valve Springs and Retainers

Upgrading cams to GSC S1's. I'm thinking it's a smart decision to upgrade a 30+ year old valvetrain. Quality is unmatched.
