Fitment Notes
Not compatible with 1JZ-GTE or 1JZ-GTE VVTi heads. May not fit all VVTi or naturally aspirated 2JZ heads—verify spring seat base clearance during installation. Alternate kits such as GSC5064, GSC5066, or GSC5744 may be required for proper fitment in non-GTE applications.
Why Beehive Springs?
Beehive springs allow for smaller, lighter retainers—reducing valvetrain mass and improving RPM capability. GSC’s proprietary heat treatment process ensures excellent load retention and fatigue resistance, making this kit ideal for aggressive cam profiles and high-boost setups.
