ARP bolts

[old grumpy]

Anyone using ARP bolts and nuts? I am as usual worried about the con rod bolts.

Are ARP rod bolts even still available? I have one last pack in my stores, but I plan to use them this summer.

They are used everday, all over the world......I guess. Quite expensive but safer.

I have a few sets of ARP rod bolts for the Alpine engine for sale. $150 per set plus shipping

Yes, I realise that ARP bolts are used all over - I've used their bolts for many years now - particularly head studs/nuts. But I had thought that the special ARP Alpine rod bolts were NLA.

And I thought it was no APR items avaiable for Rootes engines

I've used their bolts for many years now - particularly head studs/nuts.

Are they available? I looked on the ARP site and couldn't find them.

There isn't a set for the Alpine, but I recently used a set in my Triumph Renown and I used them in my Morris as well.

Probably a stupid question but what would you expect from me.... Are con rod bolts reuasable once torqued?

Yes and no.

No if you dont know the metallurgy of the fastener enough to trust you havent gone beyond its yield strength.

Quality ones like ARP is yes, but to a limited extent.
Engine builders often keep a log of each fasteners length and toss them when the lengths go out of spec.
GOOD builders measure the stretch of the fastener instead of measuring torgue.

I use the old ones in my standard engines. I dare not use new ones since remanufactured items from UK sometimes appears to be of questionable quality
