These high quality valve springs allow for .400" of valve lift. For use with Pigsty high lift cams. Aslo suitable for Standard,  Brooklands, Nippy and Ulster cams.

When set at the correct hight these springs will provide correct seat presure and will not bounce untill around 8000 RPM.

The standard Austin spring is not strong enough. The double spring setup sits badly on the retainer and is often coil bound at full lift.   we have also seen many broken standard springs.
