The SpeedFactory 4140 head stud kit is built to handle forced induction applications up to 800+ horsepower. These studs have a 210,000 psi tensile rating, oversized forged nuts and washers for better load distribution, and a dog point design that seats the stud in the block for consistent torquing. They're a direct drop-in replacement for your factory head bolts, so you don't have to modify anything to install them.\u003c\/p\u003e\n\n  \u003ch4\u003eBuilt for Boost\u003c\/h4\u003e\n  \n  \u003cp\u003eFactory head bolts stretch and fail when you're making big power with a turbo or supercharger. Head studs don't stretch like bolts do, which keeps your head gasket sealed even when you're pushing serious cylinder pressure. The 4140 steel construction and 210,000 psi tensile rating means these studs can handle the loads that come with forced induction without pulling out of the threads or snapping.\u003c\/p\u003e\n\n  \u003ch4\u003eOversized Nuts and Washers\u003c\/h4\u003e\n  \n  \u003cp\u003eSpeedFactory uses oversized forged 9\/16 inch 12-point nuts and hardened parallel ground washers. Most head studs on the market use smaller 1\/2 inch nuts and washers. The bigger nuts and washers spread the clamping load over a larger area, which reduces the stress on your cylinder head and helps prevent cracking around the stud holes. The 12-point design also makes it easier to get a socket on the nut in tight spots.\u003c\/p\u003e\n\n  \u003ch4\u003eHex Broach and Dog Point Design\u003c\/h4\u003e\n  \n  \u003cp\u003eThe top of each stud has a 3\/16 inch hex broach cut into it, so you can use an allen key to thread the stud into your block without fighting it. The bottom of the stud has a dog point that seats into the block and preloads the fastener, which gives you consistent and accurate torquing. You're not guessing if the stud is seated properly or torqued right.\u003c\/p\u003e\n\n  \u003ch4\u003eBlack Oxide Coating\u003c\/h4\u003e\n  \n  \u003cp\u003eThe studs have a black oxide coating that resists corrosion. If you're running the car in wet conditions or storing it for long periods, the coating keeps the studs from rusting.\u003c\/p\u003e\n\n  \u003ch4\u003eComes with ARP Assembly Lube\u003c\/h4\u003e\n  \n  \u003cp\u003eThe kit includes ARP Ultra-Torque assembly lubricant. Use this lube on the threads and under the washers when you install the studs. It gives you accurate torque readings and prevents galling.\u003c\/p\u003e\n\n  \u003ch4\u003ePair with SpeedFactory MLS-HP Head Gasket\u003c\/h4\u003e\n  \n  \u003cp\u003eFor the best sealing setup, pair these head studs with a SpeedFactory Racing MLS-HP multi-layer steel head gasket. The combination of studs and a quality MLS gasket is what you need to keep your head sealed at high boost.\u003c\/p\u003e\n\n  \u003ch4\u003eWhat You Get\u003c\/h4\u003e\n  \n  \u003cul\u003e\n    \u003cli\u003e10 pieces SpeedFactory Racing 4140 head studs\u003c\/li\u003e\n    \u003cli\u003e10 oversized forged 9\/16 inch 12-point nuts\u003c\/li\u003e\n    \u003cli\u003e10 hardened parallel ground washers\u003c\/li\u003e\n    \u003cli\u003eARP Ultra-Torque assembly lubricant\u003c\/li\u003e\n    \u003cli\u003e210,000 psi tensile rating\u003c\/li\u003e\n    \u003cli\u003e11mm diameter studs\u003c\/li\u003e\n    \u003cli\u003e3\/16 inch hex broach for installation\u003c\/li\u003e\n    \u003cli\u003eDog point design for consistent preload\u003c\/li\u003e\n    \u003cli\u003eBlack oxide coating\u003c\/li\u003e\n    \u003cli\u003eDirect drop-in replacement for OEM head bolts\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch4\u003eFits These Engines\u003c\/h4\u003e\n  \n  \u003cul\u003e\n    \u003cli\u003eB16A (B series VTEC)\u003c\/li\u003e\n    \u003cli\u003eB18C1 (Integra GS-R)\u003c\/li\u003e\n    \u003cli\u003eB18C5 (Integra Type R)\u003c\/li\u003e\n    \u003cli\u003eB20 VTEC (B20B with VTEC head)\u003c\/li\u003e\n    \u003cli\u003eLS VTEC (B18A\/B with VTEC head)\u003c\/li\u003e\n    \u003cli\u003eK20 (all variants except K20C)\u003c\/li\u003e\n    \u003cli\u003eK24 (all variants except K24Z7)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch4\u003eDoes Not Fit\u003c\/h4\u003e\n  \n  \u003cul\u003e\n    \u003cli\u003eK24Z7 (2012-2015 Civic Si engine)\u003c\/li\u003e\n    \u003cli\u003eB18A\/B with non-VTEC head\u003c\/li\u003e\n    \u003cli\u003eK20C (2017+ Civic Type R engine)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e These studs are for B series VTEC engines and K series engines only.
