The issue your running in to is the aftermarket doesn't have any idea what was STOCK on YOUR motor. A 'GOOD' shop can run the VIN and know exactly what motor was in it, and get the correct spring.

The dealership is honestly probably your best source on this and YES, you can buy just 1 spring from GM. If you know the spring rate, ID OD and installed height,,, then you can find a aftermarket spring that will work.

OR an option,,,, if it's that white dually in your avitar,, you COULD just sell me the truck and end your valve spring misery (LOL) been looking for a nice 97-99 1ton crew,, and yours is even my favorite color <grins>

When you're dead, it's only a problem for the people around you, because you don't know you're dead. .....It's kinda the same when your STUPID. I just did my taxes and reviewed my SS statement. Thanks to the current administration it looks like I will only have to work till noon on the day of my funeral.
