GSC Power-Division billet 7008R3 is designed to rev between 6500-10500 RPMs and can be used with a stroked engine or stock 2.0L displacement engine. This profile is best suited for topend power for drag and standing mile style setups. The peak lift of 12.0mm intake and exhaust will require upgraded valve springs and a titanium retainer. It is suggested to run the GSC5078 or gsc5079 Ti retainer with conical spring..

The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. 

**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**

GSC Power-Division billet 7008R1 is designed to rev between 3500-7500 RPMs and can be used with a stroked engine or stock 2.0L displacement engine. This profile is best suited for quick throttle response and midrange power being the main target powerband. This profile is best suited for track or autocross style setups. The peak lift of 11.0mm intake and exhaust will require upgraded valve springs and a titanium retainer. It is suggested to run the GSC5041 Ti retainer spring kit..

The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. 

**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**

GSC Power-Division Beehive Valve Spring Kit with Ti retainer for all 4G63s includes 16 titanium retainers and 16 beehive valve springs. This kit is capable of 10,500 RPM with as much as 12.1mm lift cams (net valve lift max due to seal to bottom retainer contact). These are 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. Our beehive spring utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.

• Max RPM: 10,500 RPM
• Max boost: 44 psi
• Up to 12.1mm lift cams

GSC Power-Division High Pressure Conical Valve Spring with Ti Retainer for the Mitsubishi 4B11T includes 16 titanium retainers,16 conical valve springs, and 16 valve spring seats. True conical valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics. Of the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components. This level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

• Max RPM: 11,000
• Max boost: 55 psi
• Up to 11.30mm lift cams

GSC Power-Division Beehive Spring Kit with Titanium Retainers for the Mitsubishi 4B11T includes 16 titanium retainers and 16 beehive valve springs. Our beehive spring utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control. 

• Max RPM: 9,500
• Max boost: 40 psi
• Up to 12.2mm lift cams

GSC Power-Division billet S3 cams for the Mitsubishi Evo X are designed for those with 800+ HP in mind. Thoroughly tested in the English Racing/ETS Evo X to ET's as low as 8.35 at over 174mph in the 1/4 mile. 

• Designed for a rev range of 4500-9500 RPMs
• The S3 cams require an upgraded valve spring
• The S3 profile should be setup with either a 0° callout for exhaust MIVEC or with a fixed exhaust cam gear
• Forged billet core
• Made 100% in the USA

GSC Power-Division billet S2 cams for the Mitsubishi Evo X are designed for those with 600+ HP in mind. Gains of 40-80 WHP (depending on turbo) have been seen by simply bolting the S2 cams in.

• Designed for a rev range of 3800-8500 RPMs
• The S2 cams require an upgraded valve spring
• Forged billet core
• Made 100% in the USA

GSC Power Division Billet R2 Cams The billet 7009R2 is a high lift, very aggressive profile with a short overall duration to keep a lower usable RPM band. The 7009R2 is designed to rev between 4000-8500 RPMs and should be used with a stroked engine or added displacement engine. The peak lift of 12.10mm intake and 12.00mm exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance. With the lift of this profile, it is suggested to only use the 5041/5040 Ti retainer and spring kits due to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500 RPMs without float or flutter issues. The profile will work fine on the OEM rocker arm and the zero-tick lifter or with the OEM lifter. We have seen gains of 25-30 WHP over the S2 profile on the stroked applications, with much more possible when used with a ported head and aftermarket intake manifold.

**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**

GSC Power-Division billet 7009S3 cams are a hydraulic lifter profile for the Evo 9 4G63. These cams are meant for 700+ WHP to take advantage of a very large turbo. These are NOT suggested for anyone running smaller. GSC Power Division S3 Camshafts 4G63

GSC Power-Division Beehive Valve Spring Kit for the EVO 8/9 includes 16 beehive valve springs only.
