M30 Heavy Duty Single Valve Spring Set

M30 Heavy Duty Single Valve Spring Set

Regular price $125.00 Sale

Heavy duty single valve springs for the M30 engine. These springs will work well with a stock or mildly upgraded camshaft. 

These springs are nearly identical to the spring pressure rates of the dual valve springs found on the late M30 heads made after 09/1986. This means that this is an inexpensive replacement option for those springs. No additional hardware is needed.
