Engine Hardware for BMW 5 Series E39 (1996-2003)

Clear BMW chassis

Please ensure your correct model is selected

Most engine hardware including head studs, VANOS bolts, and exhaust studs can only be used once. While most of the accessory bolts and miscellaneous hardware can be re-used it is often handy to have a spare bolt or bracket just in case one breaks. Any aluminum bolt, such as those found in the N52 engine MUST be replaced no matter the age or visual condition.

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
1995-1995 S50US 3.0 liter including 1995 M3 (US only)

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 47mm length factory BMW rod bolts with part number 11-24-7-589-671 (11247589671) Check applications before ordering! Opened ARP bolt kits are not
