MHS .550" Lift Stage 1 3V Valve Springs
MHS / PAC Stage 1 3V Valve Springs
The MHS / PAC Stage 1 Valve Springs for the 4.6L / 5.4L 3 Valve Heads are a great choice for all applications with aftermarket Camshafts that are still using the factory VCT and are not locked out. Manufactured by PAC Racing right here in the USA! These Springs use an installed height of 1.640" instead of the typical 1.670" 3V Springs and will include a set of 24 .030" shims for the correct installed height and MHS 4130 Chrome Moly Retainers.
