ARP 2344301 Pro Series Cylinder Head Studs, With 12-Point Style Nuts, For Select Chevrolet Small Block Applications
Model: 234-4301 | Mpn: 2344301 | Ean: 0672036009021 | PartNumber: 2344301 | Asin: B000CFQ642
ARP uses a premium grade 8740 alloy, which is rated far superior to "aircraft" quality, for their Pro Series cylinder head studs. Each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi to ensure complete heat penetration. Then the studs are centerless ground to make them as close to perfectly concentric as possible, unlike lesser quality studs. 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. By being thread rolled after heat-treat, these studs have about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it's tough on tooling, but the results are well worth the extra effort. This cylinder head stud kit comes complete with premium quality parallel ground washers and compact 12-point style nuts for select Chevrolet small block applications (23 degree OEM cast iron and aluminum Chevrolet, Gen III Vortec/Truck; AIrflow Research, Brownfield; Brodix -8, -10, -11, Track I, Dart Sprotsman and Dart II and most Edelbrock, Trick Flow).
Features
- The choice of many top professional engine builders for their all-out competition powerplants
- Manufactured from a premium grade 8740 alloy that is heat-treated to 200,000 psi, which is considerably stronger than Grade 8 hardware
- Kit comes complete with premium quality parallel ground washers and compact 12-point style nuts
- 1000% better fatigue strength than many other studs
- Centerless ground to be as perfectly concentric as possible

ARP 250-4203 Head Stud Kit

FitsAll Powerstroke Ford Diesel 6.4 LEngines2008-2010 ARP cylinder head stud kits are precision centerless-ground and thread-rolled to Mil-S-8879 specs. Their black oxide finish protects them from wear and corrosion, and ARP throws in hardened parallel washers for uniform load distribution and accurate torque readings. Picture is for refernce only and not the actual kit. Headstud kit for 6.4L isrecommended anytime power levels reach or exceed 600hp. To overcome head gasket failures that can occur in diesel engines employed in truck and RV applications, industry leader ARP has introduced extra heavy-duty head studs for this popular Ford application. These ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures. The studs are manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. The ends of the studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.

BMW 530, 535, 635, 735, 12-point nuts and under cut studs, ARP Head Studs 201-4602ARP Head Stud Kits with 12-point Nuts and Under Cut Studs . It is for good reason that virtually every top professional engine builder relies on ARP head studs for their all-out competition powerplants. Simply stated, theres not a better stud setup on the market today.For openers, ARP Head Stud Kits uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.Following heat-treat, each ARP Head 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. Its 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 Head Stud Kits are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that wont happen with inferior quality head studs.ARP Head Stud Kits are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because its tough on tooling, but the results are well worth the extra effort.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
