GSC Power-Division Race Conical Spring kit with Ti Retainer 4G63T
Trying to break records? Trying to win races? This is the valve spring kit for the 4G63T that will allow you to take your engine package to the next level. Not for street cars or sub 1,000 HP builds, in that case please see our GSC5040 or GSC5041 beehive spring kits.
Capable of controlling the valves with 60+ psi of boost at 11,000 RPM with 12.1mm lift cams. In racing, every tenth of a gram matters, so our redesigned Ti Retainer is 10% lighter and smaller, while still adding the strength needed to keep the valvetrain in one piece at 11,000 RPM.
The GSC5097 kit also includes our GSC4041 chromoly CNC replacement valve spring seats that are 0.035" thicker than the OEM part.
Able to use NEW OEM valve spring keepers or our GSC1003 keeper kit.
No need for special aftermarket locks that have the potential of being the wrong angle. Sold as a set: 16 conical valve springs, 16 Lightweight Ti Retainers, 16 thick CNC chromoly spring seats.
