Yah in retrospect i shouldve gone ARP. Too late now. but should be ok for under 6000 rpms and 300 hp . Right ?? LOL
They sound more expensive now,but for the added peace of mind its CHEAP insurance.

Carillo uses SPS bolts in some of their connecting rods.

That should tell you something.

Re Ebay them...........

If they are real SPS bolts, they're probably as good, if not better than ARP. You can always contact SPS and give them the dimensions and style of bolt you received, and I'm sure they'd be more than happy to elaborate on what identifiable markings they put on them from the factory.

Just because they aren't ARP, does not mean they're garbage. ARP has just become a household name for quality fasters, and rightly so. But it's not like they have a magic nut n' bolt factory that makes stuff at a higher tensile strength than everyone else in the world.
