LBZ: Injector hold down studs

[x MadMAX DIESEL]

The nuts in the SoCal kit are beveled yes. I don't remember if the stock hardware is like that or not? But 100% yes on bevel on after market... To be clear, the studs are arp forsure. I'm gonna go and guess the nut is aswell. But it could be some other brand

Ya the factory bolt has a bevel so it centers in the holdown. If aftermarket is the same it should work fine.

The studs cost 20 bucks

anybody have any luck with just the studs/nuts from ARP?

I gave up and just bought new GM bolts. When someone starts selling studs and nuts seperate I might look into them next injector swap.

Dirty hooker can get just the stud and nut kit for those interested.

I have some studs I would like to use at home. Has anyone got a arp number for the nut only ?

Kevin said DHD can get them two posts up. We have ran 1500+ hp @ 70 psi for couple seasons on GM(new) hold downs and bolts. Always fresh washers and never a problem. Had an injector sealing issue at the end of season last year, so i ordered billet hold downs and studs but later found out it was a head issue anyway....
