This ARP main stud set is for the S54 3.2 liter, as found in all 2001 to 2006 E46 M3, as well as the 2006-2008 Z4 M Roadster and M Coupe models. Switching to the ARP main stud kit eliminates main cap walk and fretting, as well as protects the threads in your engine block. Each stud is made using the best materials, process, design and engineering, which exceeds even the most stringent racing and aerospace specifications. This S54 main stud kit includes hardened parallel-ground washers and aerospace quality nuts.

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. On the E30 M3, there's no reason to settle for anything less than the best, which is why we carry and use ARP fasteners and studs on our own BMW race cars.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

NOTE: These bearings are now sold as SP1534F which features a new and improved silver oxide coating that is stronger and more durable! Designed and manufactured by Clevite to BE Bearing specifications. These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure. Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil. These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating. Lead-copper design for greater durability and easy tracking with oil analysis like Blackstone (recommended). Designed with extra clearance to "fix" the BMW rod bearing design flaw. Designed for use with factory 10W60 weight oils. Tri-Armor coated for low conditions during cold start Ideal for start-stop vehicles Applicable for BMW engines S54 Standard size Sold as complete set (6-cylinders) Fits the following BMWs: 2002-2006 E46 BMW M3 S54 2002-2003 Z3 BMW M Coupe, M Roadster S54 2006-2008 Z4 BMW M Coupe, M Roadster S54

Achilles Motorsports uses an extremely hi-tech Dry Film Lubricating process that will keep friction to a minimum allowing your engine to rev faster without worry while keeping oil temperature lower. Perfect for high-performance street, sprint, or endurance racing engines, this specialized coating protects vital engine bearings on dry engine starts and during extreme temperatures and high RPM operation. This specialized coating is the same process that is the choice of professional engine builders around the world, used on all NASCAR, ALMS, and Grand-Am engines. Achilles' bearings provide increased insurance against mechanical thermal breakdown compared to the OEM type bearing, showing much less wear during routine inspections. Note For high-performance and racing engines, we strongly recommend upgrading the OEM type connecting rod bolts to an ARP Connecting Rod Bolt Set to keep your bearing and caps tight even under the most extreme conditions, eliminating potential walk and bearing problems. As with all racing and performance bearings, professional installation is required. Please check all clearances as per the manufactures specifications.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our intake valves are made exclusively from an enhanced versions of EV8 (21-4N) steel. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves.

New rocker arms (cam followers) are required during any new camshaft installation on the S54 engine. Otherwise the original rocker arm will wear the new camshaft lobe unevenly. These are the Original BMW S54 rocker arms and used on the original E46 M3 CSL cams as well. While these are fine for CSL cam upgrades or the Schrick 280/272 cams, the Schrick DLC rocker arms are better all around, especially when used with the more aggressive 288/280 or higher cams.

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the M50/M52/S50/S52 engines that were used in a variety of BMW models. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best. Installation Instructions: To ensure accurate torque readings and proper thread engagement, thoroughly clean all threads in the engine block. If necessary, use an ARP chaser to chase the threads. Before installing any hardware, carefully inspect and clean it for defects, shipping damage, and proper fit, length, and dimension. Gently screw the main studs into the engine block by hand until they are snug. Install the main caps, checking for any binding or misalignment. Apply ARP Ultra-torque fastener assembly lubricant to the threads of the studs, nuts, and washers. Install the washers and nuts onto the studs and tighten them by hand. It is highly recommended to use the ARP Ultra-torque fastener assembly lubricant provided with the kit, as it provides consistent clamping force and reduces friction on the studs. Do not use motor oil or other low-quality lubricants. PRELOAD (TORQUE) RECOMMENDATIONS 7. Following the manufacturer-recommended torque sequence tighten the nuts in steps 1-3 Step 1: Tighten to 20 ft-lbs. Step 2: Tighten to 40 ft-lbs. Step 3: Tighten to 60 ft-lbs. With the included ARP Ultra-Torque fastener assembly lubricant
