ARP 202-4701 Head Studs



FITS CAST IRON SLANT 6 ENGINES.

(VQ35 (U-Cut) 12 Point) Built for the Nissan 350Z... 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!

Easy interface

Awsome service and prices,Thanks alot

Great to deal with both online and over the phone. Buy with confidence.

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

great price, fast shipping, my third time ordering from autoplicity

Great prices and super fast shipping. Found my new online parts store!

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.

I found great prices and they shipped immediately. Best deal online.
