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.

These King Performance Series bearings are recommended for performance applications. These bearings are designed for aftermarket gasoline or diesel engine rebuilding and performance engines with OE or upgraded crankshafts. These King Performance Series bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. The bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow.
