There are many variables that come into play when determining the proper fastener for a particular application. That’ s why ARP has developed over 100 kits for SBC, BBC and LS Chevy OEM and aftermarket engine block / cylinder head combinations alone. This precise attention to detail assures optimum combustion chamber sealing and long-term reliability; no“ universal” kits here!

Critical dimensions for optimum fitment:

• Counterbore Depth

• Gasket Thickness

• Counterbore / Spot Face Width • Thread Stop Depth

• Stud / Bolt Hole Depth • Block Hole Depth

• Stud / Bolt Hole Diameter • Overall Thread Length

• Thread Start Depth

• Thread Size & Pitch

No compromising materials

Steel alloys come in various grades of purity. ARP uses only the best, which are superior to“ aircraft” or“ commercial” grade.

No compromising heat treat

ARP does it all in-house under precise computer control. Studs are individually placed in special racks( not dumped in a bin) to assure total 360-degree penetration.

No compromising strength

Choose from five premium grade alloys ranging from 8740 chrome moly( 190,00 psi) through ARP2000 ®( 220,000 psi) plus L19, Custom Age 625 + and

ARP 3.5 ® that have nominal tensile strength ratings up to 280,000 psi.

No compromising concentricity

Each ARP stud is centerless ground to assure concentricity. The ease of which cylinder heads can be slid into position is a testament to that accuracy.

No compromising threads

ARP rolls each thread( not cuts them) to SAE AS8879D specifications— the industry’ s most precise standard. And because they’ re rolled after heat-treat, when the material is harder, fatigue strength is improved by up to 20-times.

All ARP fasteners are proudly manufactured in-house using only the highest grade materials www. arp-bolts. com 800-826-3045
