Newby 12v question... What is the spring rate of the valve springs in the 4k GSK. I just picked up a 98 12v with an Exh. brake. I assume it has 60# springs. I cannot find a post about what rate springs to use with the 4k GSK. Thanks for your time, Joseph

Joseph,
it is recomended to use the 60LB springs to spin 4K
they can be found here BBD Performance 60lb Valve springs
also see here for more info on your truck 5.9L 12V Bombs (Aftermarket) - Diesel Bombers
Thanks,
Brice
