Review on Mile Marker 501 Transfer Conversion by Lokesh Das

Revainrating 5 out of 5

Perfect for my 1979 GM NP203

This kit will turn your stock 4x4 NP203 transfer case into a part time job. This matched my NP203 perfectly in my 1979 Blazer. I assembled the whole body when I bought this kit. Installation isn't that hard, but it's not that easy either. When disassembling this case, many needle bearings fall out. You must be very careful. From what I googled there is another incomplete kit that replaces the entire output shaft and should be stronger. I tried to find this model but it looks like it is no longer made so I had to settle for this one.

Pros
  • Confident
Cons
  • Out of fashion
