GSC 268/268 Billet R1 Camshafts Mitsubishi 4G63T Evolution 4-8

The 7008R1 is a high lift, aggressive profile, with a short overall duration to keep a lower usable RPM band. The 7008R1 is designed to rev between 3500-7500 RPMs.  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*
