The VAC Motorsports ARP Head Stud Kit was put together by VAC and ARP’s finest engineers. This is a completely custom kit designed specifically for the almighty N54. *High Boost (25+ psi application) option features: (14) 11mm ARP Head Studs (14) ARP Washers for 11mm Studs (14) ARP Nuts for 11mm Studs Install Tips: MUST drill and tap the (4) 9mm holes in the engine block to make them 11mm holes. This way all the engine block holes are 11mm, and fit ALL (14) 11mm Studs. Torque Specs: All studs torque down through 3-equal steps to 95 ft lbs ***This is NOT the Chrysler and Volvo stud kits! VAC Motorsports and ARP engineers designed and assembled this kit with high grade material, specifically so standard street-use or high-boost N54 owners have a PROPER kit that does not fail over time, such as the retro-fit Chrysler and Volvo head stud kits. ARP is the world leader in fastener technology. Makers of the finest fasteners in the market, especially for BMW engines, ARP is the brand you can count on when you want the highest reliability possible. If you are looking for high performance from your BMW engine, then ARP Head Stud Kits are a must. All kits come complete with hardened parallel-ground washers and aerospace-quality nuts.

Despite the fact that BMW engineers some of the worlds most revered engines, during number crunching something always has to be a compromise. One item that is always found to be a weak point- the OEM hardware. It is definitely sub-par for real performance use under high stress such as modded engines and track use. We use these fasteners on all of VAC's in-house head builds. Whenever the head is coming off, your switching to forced induction, or if you are simply prepping to drive your car hard; we highly recommend switching to far superior race-grade hardware. These Head Stud Kits greatly improve reliability; helping to eliminate movement of the of the cylinder head and intern, gasket failure caused by inferior OEM head-bolt stretch. This is the #1 cause of premature head gasket failure, especially on boosted or high output engines. Though more expensive than OEM, converting to one of VAC's head studs kits will not only give added strength and reliability when its needed most, but provides the most accurate torque readings because studs don’t “twist” into the block; all clamping forces are on one axis, and there is less force exerted on the normally stressed threads of the block. This increases block and hardware life and typically makes the head easier to properly install to the block, a blessing if your head may have to be removed more than once. Especially in the time crunch of racing, when engines are dissembled frequently, studs make removing and installing the cylinder head on to the block a much easier task. By allowing the studs to act as a guide on to the head, your head slides on and off and also ensures proper alignment of the head and gasket for the same reason. It is similar to converting your wheel-bolts to wheel-studs.
