ARP Head Stud Kit BMW M50 M52 M54
ARP Head Stud Kit to suit the Diff Lab engine girdle for M50, M52, M54, S50 and S54. The Diff Lab M50/S50S54 girlde kit already includes a set of these.
Also used as head studs on M50, M52 and M54. Great for race engines, and boosted engines. Though the instructions do not say so, it is a general belief that these can be torqued to ~10% higher than the ARP specs to achieve more head gasket clamping force. Do not over-tighten more than 10%, and any amount of over-torquing is performed at your own risk.
