Kelford GR Corolla Performance Beehive Valve Springs, Base and Titanium Retainer Kit - KVS264

It is well known that the factory valve springs are a weak spot on the GR Corolla G16E engine. Kelford have been manufacturing valve springs and titanium retainers for many decades and have developed a great solution with a titanium retainer to reduce the weight of the valvetrain.

The specifications of these valve springs are:
- 100lb @ 35.0mm on the intake, 198lb @ 12.0mm lift
- 87lb @ 36.7mm on the exhaust, 178lb @ 11.5mm lift
- Coil bind at 22.0mm

NOTE: Must remove the OEM spring base and fit the 8mm base supplied.
