ARP BMW M50 M52 S50US S52US 2-bolt main stud kit 201-5000
Description
BMW M50, M52, S50US, S52US, 2-bolt main, main stud kit
Main studs hold your crankshaft in place. As you make more power, and rev higher than your engine was designed to rev from the factory in stock trim, you start to push the limits of the factory fasteners.
Factory fasteners were not designed for performance use. The material chosen by the Original Engine Manufacturer for your engine's factory fasteners was chosen to meet the criteria of a normally driven consumer vehicle at the provided stock horsepower and rev limit. The material is not optimum for a high reving, high heat, high power, race car.
The factory fasteners were also not designed to be reused. Every time you torque a fastener, it stretches to perform the proper clamping force. If the fasteners stretch too far, they will not longer provide the required clamping force, and can lead to an engine failure. When you take your factory engine apart to build it into your race engine, discard your used factory main bolts and switch to a brand new set of ARP Main Studs to provide your engine with the proper clamping force required to keep all of your parts together in the harshest race environment.
ARP Main Studs are stronger than your stock main bolts.
You should not reuse fasteners multiple times (especially stock ones) - they stretch
Quality Fasteners are required to keep everything where it belongs in your engine.
