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:
1992-1995 E36 325i/is *** with 44mm rod bolts only ***
1995-1995 E36 M3 S50 3.0 liter (US model)

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.

This ARP main stud kit fits the following BMWs:
2001-2006 E46 M3 3.2 liter coupe/convertible
2001-2002 MZ3 M Coupe & M Roadster (S54 engine)

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
