ARP - Connecting Rod Bolt Kit
ARP has released a new version of their race-grade connecting rod bolts and its better than ever before. ARP S65 connecting rod bolts are precision CNC-machined to exacting specifications and designed for optimum reliability and designed for the endurance racing environment. These rod bolts are heat-treated with threads which are rolled to provide up to ten times more fatigue strength.
ARP is the world leader in fastener technology. Makers of the finest fasteners in the market, especially for BMW engines, ARP is the choice when you want the highest reliability possible. ARP Con Rod Bolt Sets give you a clear advantage over the OEM Con Rod Bolts: strength! Even cosmetically, the difference in construction and quality is apparent... If you look at many of the OEM bolts, you will see a taper on the threads which actually takes away bolt grip. ARP Pro Series connecting rod bolts are different: Precision CNC-machined to exacting specifications and designed for optimum reliability, their designed for full engagement, quality controlled in each batch, and heat-treated with threads which are rolled to provide up to ten times more fatigue strength than standard OEM BMW fasteners.
Due to the fact that the OE Connecting Rod Bolt is typically one of the first failure points in the bottom end of the BMW engine (Turbo, SC, or Naturally Aspirated), we can't recommend these bolts enough! If your rebuilding you're engine, and have any performance aspirations but cannot afford upgraded aftermarket rods; invest in much stronger ARP con rod bolts.
If you are looking for high performance from you BMW engine, then ARP con rod bolts are the best way to add peace of mind for your bottom end. In fact, nearly all high quality after market rods include ARP bolts for these reasons.
