Up-rated by 15% over standard Rover Sd1 Valve Springs with one less coil for better valve guide to retainer clearance. Made from better quality col wire and heat treated.
For use with
Kent and similar High Performance Camshafts.
Eg, H180,200,214,218
Crower 230, 232
RS Viper, Typhoon
These valve springs also feature one less coil to help eliminate coil bind on performance camshafts. Coil binding or insufficient clearance will lead to de-lamination of the valve spring and a fractured spring and sometimes, dire consequences.
