ARP Head Stud Kit, BMW S55

Upgrade the performance of your BMW S55 engine with our custom-designed Head Stud Kit, brought to you by ARP - the world leader in fastener technology.

This kit is engineered to replace BMW part #11127853937 and is compatible with the BMW S55B30 engine found in F80 M3/F82 M4 and F82 M2 Competition models.

This kit comes with 14x 11mm Studs, 14x Washers, and 14x Nuts offering increased clamping force and enhanced head gasket sealing, which can prevent head gasket failure.

This is particularly crucial for high-performance or turbocharged engines, as the increased cylinder pressure puts additional stress on the head gasket and bolts.Our Custom Age 625+ kit is made from a material with a tensile strength of 260 ksi, substantially higher than the 190 ksi of the ARP 2000 head stud.

It's an ideal choice for individuals who want to push the limits of their S55 builds.

Please note that this Head Stud Kit is not a retrofit from a Chrysler or Volvo stud kit.
