I have 16 brand new 3.1/3.4 valve springs. These are a popular and cheaper upgrade to the stock springs on 5.2 and 5.9 magnum cylinder heads for a mild cam. Drop in replacements, 3.1/3.4 or LS1 retainers required.

$80 shipped to lower 48 states

 

bump.

 

these will work with 5.9 and 5.2 magnum engines without modifications and are stiffer than stock springs

 

make me an offer
