BW4493

Two remanufactured BW4493 transfer cases are listed in this Transfer Cases category: one for the 2006-2008 Hummer H3 3.7L (vendor SKU RTC4493G-1) and one for 2006-2010 Hummer. Both are 27 spline input, 32 spline slip yoke style rear output shaft, circular front output yoke, option NR4, 2.64:1 ratio low range, AWD.

How to identify yours

Check the shift motor before you choose: the RTC4493G-1 listing does not include one, and the other includes a new shift motor. Both carry Hollander numbers 412-129, 412-636 and 412-689 and the same tag list, so match the tag on your case.
