This is a comprehensive kit that INCLUDES;
ND double valve spring set
Ti retainer set
Small valve stem seal set
This wide coil allows spring valve lifts as high as 12mm to be utilised without the fear of damaging coil bind or loss of valve control. We have run these springs over 10,000rpm, 1300Hp and 60Psi boost!
NOTE:- When using these springs the little shelf on the cylinder head needs extra clearance. We do this with a die grinder. See picture 2 for info by clicking above.
