Your cart is empty.(D16Z6) Built for the Honda Civic... Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers.You should know that ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It's important to note that lesser quality studs are not 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, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won't 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.You will 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!

Boosting my d17a. These studs will hold my head down through anything. Be aware, you will NEED a 12mm, 12 point, deep socket. I had to wait to install for a bit till I got the correct tool.

The picture is generic. My application was 2003 Honda Civic 1.7L. High quality ARP stud kit. Worked perfectly.

Fit perfectly on my JDM D15B, now will just see how long it lives under boost. I trust it will be a long time knowing ARP quality

Got these to do a full rebuild on a d16z6 in a 95 honda del sol si. For some reason, a couple of the studs would not torque in properly. Not sure if it was the block threads or a design flaw with the head studs.Either way, these were installed, 1 stud was helicoiled, and the other pretty much just sat as tight as it would go (still a tad loose), and they seemed to hold up on 20 lbs of boost with a 70mm turbo application. Can't say for how long, as 2 weeks after installation, the transmission blew on the car, and I ended up trading off.Got these with:Piston Rings: Sealed Power E-515KCMain Bearings: Sealed Power 7102MHead Gasket: Fel-Pro 9915 PT

TSB suggestion for my engine was to use a metal head gasket and not the original graphite due to gasket leak failures but once you use the metal head gasket, you couldn't use the original head bolts. Rather than buying the OEM, I opted for Head Studs since they provide a better seal. Works perfect on the D16A6.
