Makers of the finest fasteners in the market, especially for BMW engines, ARP is the choice when you want the highest reliability possible.

Our 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.

Please check your rod bolt under-head length (expressed as UHL) and diameter before ordering replacement rod bolts to ensure you get the right set: here are some popular applications and their ARP sizes:
