Dual Valve Spring & Titanium Retainer Kit for Nissan / Holden RB30 (SOHC)
This dual spring and titanium retainer assembly is engineered for RB30 SOHC applications requiring improved valvetrain control at increased RPM and moderate lift camshafts. The spring configuration supports cam profiles up to 0.550" valve lift while maintaining stable pressures across the operating range.
Spring Characteristics
- Installed Height: 1.640"
- Seat Pressure: 120 lbs
- Open Pressure: 250 lbs at 1.245"
- Coil Bind: 1.000"
- Maximum Valve Lift: 0.550"
The titanium retainers reduce mass at the upper valvetrain, improving stability and reducing the likelihood of valve float in boosted or extended-RPM conditions. The kit installs as a direct replacement for the factory components.
