GSC Power-Division Beehive Spring set with Titanium Retainer for the Subaru EJ Engines

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 inquired 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.

Beehive Spring Benefits:

Rev faster

Lighter components

More durable design

Less stress on valvetrain components

Lower spring frequency for more precise valve control.

More valve control equals more aggressive cam profiles

Nano peened for faster break in and less stressed springs

All of these items help to return more power for you to enjoy!

The GSC 5043 Beehive valve spring set, and Grade 5 Titanium retainers. This kit is capable of 9500+ RPMS, with as much

as 11.5mm lift cams.

225lbs @ .433" (11mm) Valve Lift

Coil bind @ .550" (14mm) Valve Lift

5043 Beehive Rev and Boost range (using an S3 profile camshaft set)

Max RPM: 9,500

Max boost: 35psi+
