ITEM: 210mm 3.46 M12 ring and pinion, cryo and polished
DESCRIPTION:
This gear set has a ratio of 3.46 (38 : 11) and ring gear diameter of 210mm. The ring gear bolt size is M12. No bolts are included. This is a used set that has been professionally Cryo Treated and Polished by Thayer Motorsports. These treatments both harden the metal and reduce friction for racing applications. There is one minor ding / dent to the pinion. The ring has a few dings to the top of the teeth. Details of the damage can be seen in the photos. The damage should not affect performance. This ratio and size came from the factory on Euro E28 535i models. They can be installed in any 210mm large diff case. It will not fit LW type differential cases manufactured after 2006. Guaranteed good working condition.
