Main Stud Kit by ARP

ARP main stud kits help eliminate main cap walk/fretting and protect the threads in your engine block. They include studs made from 8740 chromoly steel and heat-treated in-house to 190,000 psi tensile-strength rating. The precision J-form threads are rolled after heat-treat for much stronger threads than the competition. Kits come complete with hardened parallel-ground washers and high-quality nuts. Add confidence in the strength of your engine build with the ARP main stud kit designed for your application.

Applications

• 1975 Buick Apollo
• 1975 1980 Buick Skyhawk
• 1975 1977 Buick Century
• 1975 1977 Buick Regal

• 1978 1987 Chevrolet El Camino
• 1978 1983 Chevrolet Malibu Both the 229 cu in (3.8 L) engine used in the Malibu starting in 1980 and the 200 cu in (3.3 L) version first used in 1978 were NOT versions of the Buick 3800 Engine, but a different Chevy-built engine. Both the Buick V6 and the 229 cu in (3.8 L) Chevrolet V6 are 90-degree V6 engines, and both are often referred to as being a 3.8 L V6. These engines should not be confused as being the same, and are unique engine designs. The 229 cu in (3.8 L) Chevrolet V6 was essentially a small block Chevy V8 missing two cylinders.
• 1978 1987 Chevrolet Monte Carlo This is very confusing, as Monte Carlo at various times used both the V6 from the Buick engine as well as the V6 engine derived from the Chevrolet V8.
