Head Studs 2GR - ARP R2
For those who need above standard clamping force on your 2GR cylinder head, we now offer a complete, high-strength ARP replacement set! This is a custom R2 set of ARP bolts that comes with a complete set of 16 studs, 16 nuts, and 16 washers. This is a must-have for an engine with high cylinder pressures or forced induction.
The studs feature M11x1.5 base threads with correctly sized thread length to ensure adequate clamping forced and help prevent striping of the aluminum threads. The top threads and nuts/washers a 7/16-20 standard thread, using the included ARP washers and nuts.
We also include an extended-length M11 tap for use in installation/cleaning your block. Care must be taken when tapping or modifying an aluminum block!
