ARP are world-renowned for being top of the market whenever fasteners are involved. With higher tensile strength and durability, these studs are a must-have for any engine build, be it forced-induction or NA.

We don’t recommend using M10 studs in the BMW aluminium blocks - We always use M12 studs in the workshop, however, this is much more difficult than just replacing like-for-like sized threads.

• ARP do not have M54 head studs listed, however, the studs we supply are manufactured by ARP and have been used in many M5x turbo builds around the world without fault.

• M10x1.5 thread - same as standard blocks

• Direct fit for M52 aluminium (for steel blocks use ARP 201-4302), M52TU and M54 engines.

• Due to the amount of fake ARP bolts on the market, we will not accept returns if the box the studs are housed in has been opened.
