BoostLine BMW N54B30 145mm ARP 625+ - Connecting Rod Kit

BoostLine is known for building robust engine components, and this connecting rod kit for the BMW N54B30 engine is a prime example. If you're looking to build a more powerful N54, whether for street use or track days, strong connecting rods are a critical piece of the puzzle. These rods are designed to handle increased cylinder pressures and RPMs that come with performance tuning.

This kit features connecting rods forged from 4340 steel, a material chosen for its excellent strength-to-weight ratio and durability under stress. They are balanced to within very tight tolerances, which helps ensure smooth engine operation and reduces vibration, especially important when you're pushing the engine hard. The rods measure 145mm in length, a common specification for the N54 platform, and are designed to work with a 2.75-inch crankshaft journal diameter. The big end of the rod uses a 2.223-inch bore size. Each rod also features a 0.866-inch wrist pin bore, suitable for most aftermarket pistons.

What really sets this kit apart are the ARP 625+ bolts. These are a premium fastener from ARP, known for their exceptional tensile strength and fatigue resistance, making them ideal for high-performance applications where reliability is paramount. The kit includes everything you need to get these rods installed, including the rods themselves and the ARP bolts. It's a well-built package designed for enthusiasts who demand more from their BMW's engine.
