ARP 11mm Head Stud Kit for the 1.8T motor, fits early style (058) 4-cylinder 20-valve heads.
Perfect for high HP applications where factory stretch fasteners don't provide sufficient, consistent clamping force in high combustion pressure applications.
All Pro Series ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi. These fasteners deliver a 40% increase in tensile strength over the OEM Torque to Yield (TTY) bolts.
Price per set for one head.
NOTE - these head studs do NOT use the factory 6-point tool for tightening. Do not use the factory tightening torques or procedures for these head studs, instructions supplied!
11mm final TQ to 80 ft/lbs in 3 steps
ARP bolts utilize an "M10 Triple Square" tool and can be found on Amazon if needed.
Note: This kit if for early style 058 motors only, and will NOT fit the later
