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

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.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

Set of 12 ProSeries connecting rod bolts, made by ARP -- the world leader in fastener technology. 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 motorsport and drag racing as an upgrade from 8740 Chrome Moly in both steel and aluminum rods. These are simply the best connecting rod bolts available, making them ideal for ultra high performance, racing and forced induction applications.

This set replaces the factory BMW rod bolt number 11-24-1-739-728 (11241739728) which measures 44mm in length. 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:

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.

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. 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. Kit includes Upper and lower WPC treated rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube Connecting rod bolts

If you're the proud owner of an S54-equipped BMW, chances are you're passionate about enhancing your vehicle's performance and longevity. One crucial upgrade that can significantly improve your driving experience is Turner Motorsport's WPC Rod Bearing Replacement Kit, coupled with ARP Rod Bolts for increased durability.

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes. WPC treatment reinforces the surface of the bearings, making them highly resistant to wear, which is essential for high-revving engines like the S54. This durability ensures your engine will stand the test of time, even under strenuous driving conditions. Improved Performance: By reducing friction and wear, WPC-treated rod bearings allow for smoother and more efficient engine operation. This increases power and responsiveness, providing a more exhilarating driving experience. Whether tearing up the track or enjoying a spirited weekend drive, you'll notice a difference in your vehicle's performance. Precision Engineering: Crafted from premium quality materials, these bolts and bearings offer exceptional tensile strength and structural integrity. This guarantees that your connecting rods will stay securely in place, even during high-stress situations. Your engine's components will work in perfect harmony, minimizing the risk of catastrophic engine failure. Preventative Maintenance: The S54 is notorious for rod bearing failure, often necessitating complete short block replacement. Choosing to proactively replace your rod bearings with our WPC offering ensures smooth operation and eliminates potential engine failure. Included in the kit:

12 - Turner Motorsport "Race Series" WPC-Treated Bearing Shells 4 - Self-Locking Collar Nut - Priced Each 1 - Oil Pan Gasket - Elring 1 - Oil Pan Center Cover Gasket 1 - Oil Filter Kit 1 - Oil Drain Plug 1 - Dipstick O-ring 1 - ARP Connecting Rod Bolt Kit (M10x1.25 - for S54B32 produced after 02/2003) 6 - Castrol Edge Euro Car Engine Oil (10w-60) Quart 1 - Redline Assembly Lube - 4 oz

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine. Kit includes Upper and lower BE Bearings upgraded rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube
