GM Performance Parts 12499224 Spring PKG,VLV

I had to return the first package and ask for a replacement, warehouse messed up and sent one single spring instead of the box. This time around it’s a legitimate GM box, with hologram, correct part number, and 16 springs. Will be installing them in my 5.3 along with an aggressive cam.

No issues with the install on my 02 Z06 Corvette (LS6). These are not blue as the picture shows BUT that is because the newer springs from GM are no longer painted, they are bare metal as these ones are. Buy with confidence.

Everyone says these are good springs so I ordered a set. Pity only 15 in the box

These are good springs and the correct ones for your order. They come individually labelled P/N 12713265. This part supersedes P/N 12625033. A package of (16) 12625033 has the GM P/N 12499224. So it is the correct set of springs but the geneology takes some explanation. Also, they're not blue but that's typical for these springs.

Install them in my 2004 6 L Gmc have a bout 5000 miles on the springs. runs perfect I ordered another set doing up another set of LS heads
