Set of 12 ProSeries ARP2000 connecting rod bolts for the Euro-spec M3 engine. Made by ARP, the world leader in fastener technology. The best rod bolts available for the Euro S50 and S54. Ideal for ultra high performance, racing & forced induction applications. Each bolt is made of ARP2000 material, which exceeds the strength of 8740 Chrome Moly, and is able to achieve clamp load at 220,000psi. ARP2000 fasteners are used widely in professional motorsport and drag racing as an upgrade from 8740 Chrome Moly in both steel and aluminum rods.

This set replaces the factory BMW Euro S50B30 and B32 rod bolts with part number 11-24-1-317-184 (11241317184) and 11-24-1-405-890 (11241405890). It's also used for S54 engines with stock M10 sized rod bolts, which were used from February 2003 production and later. It was also used in earlier engines that had connecting rods replaced. For these 2001-2003 models there is no easy way to check if the rods were replaced, except by checking the rod bolt diameter. If your car has the earlier M11 sized bolt, use ARP kit #201-6103 . Before opening the ARP kit, we recommend that you check your existing rod bolt size as BMW was not consistent with their applications. ARP bolts are not returnable if the package has been open.

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.

These ARP connecting rod bolts fit the following BMWs:
1993-1999 E36 BMW Euro M3
2001-2/2003 E46 M3 coupe / convertible*
2/2003-2006 E46 M3 coupe / convertible
2001-2002 MZ3 M Roadster & M Coupe*
2006-2008 MZ4 M Roadster & M Coupe
* - these engines could have either M10 or M11 sized bolts. If the rods and rod bearings were replaced under recall by BMW it should have the newer M10 bolts and this is the correct ARP set to order.

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated to 200,000 psi, ensuring complete heat penetration. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found for the E36 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. (Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!)

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

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.

These head studs fit the following BMWs/engines (steel block only)
1992-1995 M50 6 cylinder including 325i, 325is and 525i
1996-1999 M52 6 cylinder including 328i, 328is, 323is, 528i

This main stud kit includes 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. *Does not include washers*

These bolts are M11 size to replace the stock M11 BMW bolt part number 11-24-7-834-310 (11247834310). The M11 bolt size was used in S54 engines up to 2/2003 production. However, most S54 engines up to that point had their rod bearings replaced under a factory recall and some may have had new connecting rods installed at the same time (or even a new engine altogether). The new bolts installed in these earlier engines are M10 size. Unfortunately, there is no way of knowing which rod or bolt is currently in your car (unless your car came with service records detailing when and what was replaced). The only sure way to know is to check the bolts currently installed in your engine. If yours was updated to the M10 sized bolt, use ARP kit #201-6102 . ARP bolts are not returnable if the pacakge has been open.

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.

Upgrade your BMW engine's performance with the Athena Cut Ring Head Gasket. This gasket replaces BMW part # 11121726619 and 11121726617 and is specifically designed for M50 & M52 iron block inline 6-cylinder engines found in E34/E36 chassis. Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressure before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi. A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena's gasket is crafted with premium quality reinforced M0115, an asbestos-free material that's original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2-bar boost. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Please be aware that the gasket should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Installation instructions: Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.

The 44mm BMW rod bolt was used on all US spec E36 M3 (3.0 and 3.2 liter), 1999-2000 E46 323i/323Ci, 2001-2005 325i/325Ci, Z3 1.9,2.5 and 3.2, as well as Z4 2.5. It was also used on SOME of the M50 2.5 liter engines from 1992-1995 -- but check before ordering! Opened ARP bolt kits are not returnable. If your M50 2.5 liter engine has 53mm rod bolts, you will require kit part# 201-6301 instead.

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.

These ARP connecting rod bolts fit the following BMWs:
1992-1995 E36 325i/is *** with 44mm rod bolts only ***
1995-1995 E36 M3 S50 3.0 liter (US model)

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

The M50/M52/S50/S52 engines are notorious for their well-documented problems stemming from harmonics. The vibration leads to the oil pump shaft becoming weak, causing it to either break or the oil pump nut to loosen and fall off, resulting in an immediate loss of oil pressure. Worry no more! 5150 has the solution! At the core of this kit is a hardened Chromoly shaft, meticulously centerless ground to guarantee absolute precision. This shaft is designed with an exclusive square key lock system, which not only prevents the gear from ever rotating on the shaft but also reinforces the mounting area, adding additional strength. Furthermore, we replaced the problematic oil pump nut with an extended-length bolt, which is EDM drilled to accommodate safety wire for a secure fit in all conditions. Don't wait until your oil pump fails, leaving you facing expensive engine repairs! Key Features: Centerless ground shaft made from hardened Chromoly. Bolt with EDM drilling, including safety wire. Grade 8 extended-length hardware for secure gear attachment. Left-hand threaded to prevent unexpected loosening. Double-D keyed shaft and drive gear. Fully serviceable and rebuildable without the need for grinding.

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
