Some notes, yellow stripe springs are OEM.
The HRC inner spring seat is the same thickness but has a 17mm OD (15mm for OEM) for the inner HRC spring. The HRC outer spring seat is the same as the OEM but has been ground from 1.52mm to 1.24mm thick. The thinner outer seat was to help with coil bind issues with high lift HRC cams. Both parts are steel.
