ARP M8 x 1.25 x 38mm Broached 10 Piece Stud Kit for 1994-2001 Acura Integra GS-R & Type R, 1994-1997 Honda Civic Del Sol VTEC, 1999-2000 Honda Civic Si
This ARP stud kit provides M8 x 1.25 x 38mm broached studs designed specifically for Honda B-series DOHC VTEC engines in Acura Integra GS-R and Type R models from 1994 to 2001, Honda Civic Del Sol VTEC from 1994 to 1997, and Honda Civic Si from 1999 to 2000. The 10-piece set delivers even clamp load to maintain head gasket seal under high boost and rpm. Engine builders rely on these studs for repeated heat cycles without fatigue.
Key Features
- ARP2000 Alloy Construction: Forged steel with tensile strength over 200,000 psi resists stretch and failure in boosted or high-compression setups
- Broached Hex Drive: 12-point broach ends allow secure wrench grip and prevent stud rotation during torquing for accurate preload
- Stud-Over-Bolt Design: Pulls evenly on head without damaging block threads unlike bolts that can gall aluminum
- Precise Thread Rolling: Rolled threads increase fatigue resistance and ensure consistent torque values across all 10 studs
- Application-Specific Length: 38mm underhead length matches B16A B18C cylinder head height for optimal stretch and clamping
Product Notes
- Confirm engine code B16A2 B16A3 B18C1 B18C5 prior to purchase for exact match
- Inspect studs for thread damage before reuse after disassembly
- Compact kit ships in protective ARP packaging to prevent corrosion
Installation Notes
- Professional installation recommended.
- Clean blind holes with ARP thread chaser and apply ARP Ultra-Torque fastener lubricant on threads and under heads
- Torque to ARP spec of 60-65 ft-lbs in 3 steps following 3-stage sequence for B-series heads
