Also known as 60lb over stock HD Valve Springs or 60# over HD Valve Springs

Sold per set of eight (8) & one (1) 3200 gov spring.

For installing on intake and exhaust valves & gov spring for VE inj pump.

These heavy duty exhaust valve springs are required if you plan on running any exhaust brake or higher than stock rpm and or higher boost. Completely safe spring pressures, even for stock running components.

The seat pressure on these springs is ~150 lbs at the installed height

If you have a mechanical 4bt or 6bt and are going to install an exhaust brake or turn higher than normal rpm or run higher boost than stock, you don’t have strong enough valve springs to effectively hold the valves close.

If you plan on running over 40lbs of boost or turning over 3700rpm, then you should consider a stronger set of valve springs then this set.

Don’t be fooled by people selling cheap GSK’s and valve springs out there. A broken spring will take out an engine. 

Note : Make sure you read the instructions found on our site or available on many other sites on how to install the spring properly. Not a hard job to do if you do it right. Make sure you back out the power screw until you see the black o-ring before installing top on pump, or you will bend the fulcrum lever.
