This is a set of takeoff valve springs from a stock Chevrolet Corvette Z06 C6 427. These are the set of beehive springs, retainers and locks. These are a very high quality spring that GM used on their flagship sportscar.
We took them off to upgrade the heads to a set of dual springs. These have been washed and cleaned. We will verify the spring pressures on all the springs before we send them out.
This is a complete set of 16 spring, 16 retainer and 32 locks. These very in mileage on them due to us not removing them from the car ourselves.These springs will not fit any other LS heads. The installed height is different. We have used these springs in other application, but your cylinder head person would have to verify if they would work for you. These springs are $11 each at summit racing.
