Engine Studs

Engine studs take the place of bolts in high-load joints such as cylinder heads and main caps. The stud threads into the block and stays put, while a nut on top supplies the clamping force. Because the threads in the block are not turned every time the engine comes apart, studs help protect those threads and tend to give more consistent, even clamping. Builders often fit them when adding power or rebuilding an engine they expect to take apart again.

We currently have 4 engine studs in stock, all from ARP. Examples include the ARP M10 x 1.25 ARP 2000 Stud with Guide, sold as one stud, and the ARP M10 x 4.50in - 1.25 Broached Stud.

  • Match the thread size and pitch to the hole you are filling.
  • Check overall length so the stud seats fully and leaves enough thread for the washer and nut.
  • Confirm how many studs the job needs, since some are sold individually.
  • Follow the manufacturer's lubricant and torque instructions.

To narrow the list to parts for your engine, pick your vehicle to see what fits.
