Crankshafts

The engines crankshaft takes all of the explosive energy from the pistons and translates this to the drivetrain. When bearings spin due to improper maintenance or oil starvation, the shaft can become scored and is no longer serviceable. Turner carries Genuine BMW replacements that fit and perform exactly as intended

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.

What's better than using Original BMW connecting rod bearings in your next engine build? WPC-treated OEM bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or rod bearing service!
