Why Upgrade to Studs?

Compared to factory bolts, ARP studs provide:

• More consistent clamping load
• Better sealing under boost and high compression
• Reduced fastener stretch
• Improved reliability under extreme conditions
• Easier engine assembly accuracy

Basically, they keep important engine parts from separating violently.

That’s why ARP head studs are popular among leading Sport Compact/Import racers.You will have to know that ARP uses a premium grade 8740 alloy that may be rated far superior to “aircraft” quality.

Then, each and every stud is precisely heat-treated to 200,000 psi. Following heattreat, each and every stud is centerless ground to make it as close to perfectly concentric as imaginable. This procedure involves about ten very slight cuts and ends up in an exceptionally straight part.

Perfect For

• Turbo builds
• High-compression engines
• Track cars
• Engine rebuilds
• High-horsepower street setups

If your engine build includes words like:

• “boost”
• “built motor”
• “E85”
• “two-step”

…ARP hardware should already be on the list. Looking for how to build a reliable LS/VTEC?

You have to note that lesser quality studs don’t seem to be even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances,

Why ARP Matters

Cheap fasteners:

• Stretch
• Lose clamping force
• Fail under stress

ARP hardware is trusted because:

• Aerospace-grade materials
• Precise manufacturing tolerances
• Proven motorsports durability
• Trusted across racing worldwide

There’s a reason serious engine builders default to ARP.

You are going to note that gaskets and cylinder heads literally drift into position and are perfectly aligned something that may not happen with inferior quality head studs.ARP studs are thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat.

Installation Notes

• Follow ARP torque specifications exactly
• Recommended to use proper ARP lubricant where specified
• Professional installation strongly recommended for engine-critical applications

(Guessing torque specs is how engines become content for failure compilations.)

You are going to also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force one that compensates for head gasket compression when the head is installed.

This helps prevent blown head gaskets, and assures optimum sealing!

Final Take

No horsepower gains directly.

But this is the hardware helping your engine survive the horsepower you already have—or plan to make.

And honestly, that’s money well spent.
