Posi rear differential factory option?
A few questions here.they come from seeing a SPID for a 72 K-10, (4spd equipped) on a FB truck page.
The SPID listed a POSI Traction Rear differential. How common are the and/or are they hard to find? Whatever Gear would have been in this Rearend? ( I’m assuming it would be 4.10) If I were to find one, would it be possible to change the 4.10 to a more Highway sensible ratio (3.55 or lower )? Last question would be: what would the Factory Part numbers be? (So that I know that I’m getting an Actual POSI unit) My current rear end is a “One Wheeler” and I’d sure like to change it over to a POSI unit. ![]() |
