ARP Head Bolts now available in 9 x 1.25mm



Scuderia Topolino can now offer a quality replacement for the original Fiat and Abarth head bolts.  In recent times we have seen a significant increase in head bolts that have been overstressed.  This results in stretched threads and in some cases broken head bolts.

These quality replacements are made from8740 steel, with a rating of 160,000 KSI , and feature an undercut shank and rolled threads for ultimate reliability.  These can be used with the original Fiat 9mm washers or with special ARP hardened washers.  These bolts have 10mm, 12-point heads and are rated at 50 lb/ft (7 Kg/M) of torque.  Price is USD$128 (95 Euros) per set.
