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.

Under extreme conditions, these M10 studs should be replaced for M11 or M12 studs, however, until you’re making over 850hp these are enough to keep your head clamped to the block.

• ARP number 201-4302

• M10x1.5 thread - same as standard steel blocks

• Direct fit for M50 and steel M52 blocks (for aluminium blocks, see M54 studs)
