After a couple of months working on this at SME. I have developed a very cost effective crank hub solution that I can sell for nearly half the price of competitors. These all start off as brand new genuine BMW crank hubs. I then transform them into true 2 pin pressed crank hubs! Pins are made out of extremly strong bearing steel, entire crank hub is forged steel. I now use these in all of my stage 2 and higher builds. I have developed 6 kits and sold them all before they were even done. Will have more ready in 3 weeks! Can ship worldwide. These are made in the USA and in house.

SME 2 pin crank hub

These kits will be sold for

N54/N55/S55

Full kit includes

New 2 pin crank hub
New Guide
New crank hub bolt
New crank hub guide bolt
New drill bit
New dampener bolts

$600

The “my guy can do it cheaper special” customer took this to a shop and supposedly had it repaired. Looks like they didn’t even clean it and literally slapped on a new front seal with some orange gasket maker. No worries. I’ll get this guy sorted!
