Bolts for a Dana 60F

[1HighK5]

I just added some zero rates to my front springs to level out the truck a bit. I need to get a longer set of the regular bolts for the spring plate on the diff side. Are they just some grade 8 ones ?

Thats what I run.

grade 5 is fine, but if your feeling saucy, go grade 8

5/8" X 11tpi grade 8 is what you need. Just figure out your length. Probably going to need something in the 4" to 4 1/2" range for length depending on your spring pack. Make sure to not go too long....it wont tighten up. Stick the dumb end of a digital caliper down in the hole to ck your hole depth. 1.5 times your bolt diameter will give you max holding power as far as a minimum depth for the bolt to screw in. So, for a 5/8" bolt, you would need to screw it in 15/16" deep to get the max the bolt will do without breaking.

better yet, run studs/nuts...

The more I look at it the better I like the stud and nut idea. Where would I be able to get grade 8 stud/nut.
