Designed for all Subaru EJ20, EJ22, and EJ25 engines, HCR 11mm Head Studs significantly enhance engine performance and reliability compared to standard cylinder head bolts. These studs are highly recommended for engines pushing up to 550hp.
Our improved thread design has been rigorously tested to provide the best solution for clamping cylinder heads onto the block assembly, reducing the risk of head lift under high boost conditions.
Set Includes:
- 12 HCR 11mm head studs
- 12 nuts
- 12 washers
- 1 ARP Ultra-Torque assembly lube
- Fitting installation instructions
For engines aiming for more than 600hp, we recommend upgrading to a series of precisely manufactured 14mm threads. This upgrade ensures superior performance and reliability for high-powered builds.
