- M12 Studs : 20 ARP2000 Studs with nuts and washers
The dimensions are exactly to manufacture specifications and no adjustment to the block is necessary. We reached out to ARP to manufacture these ARP2000 to ensure enough clamping force to handle high horsepower over stock for street and track builds.
These studs are for McLaren M840T and will also work on M838T.
Why choose ARP2000 over our L19 head studs?
ARP2000 are most commonly used when upgrading/replacing over stock head studs due to their low cost compared to any of the tool steel fasteners and higher clamping force over stock head studs. Compared to L19 they are less susceptible to hydrogen embrittlement and stress corrosion making it easier to handle. For cars making less then 1300HP where clamp load isn’t as critical and seeing extreme amounts of cylinder pressure this is the best cost effective option.
ARP2000
Material type: Modified 8740 alloy with enhanced alloying/heat treat
Typical tensile strength: ~220,000–230,000 psi
Best for: High-performance street and track; moderate-to-high boost
ARP2000 delivers higher strength and fatigue resistance versus 8740, maintaining clamp load under elevated cylinder pressures. It’s an ideal all-rounder for boosted builds.
ARP L19
Material type: Enhanced alloy/tool-steel family
Typical tensile strength: ~260,000 psi
Best for: Extreme boost/nitrous; drag and endurance where clamp load is critical
L19 significantly improves ultimate strength and stretch resistance for severe duty. Handle and store carefully—L19 is moisture sensitive and should be kept clean and lightly oiled.
