Locking differential option on my Blazer
in checkign my SPID turns out that my Blazer originally HAD a locking differential on it form factory.
Questions: 1. Were these just at the rear? 2. Am I right to assume that this was an automatic locker and only engages IF one wheels is starting to spin (in mud maybe?) 2. How do I determine if this is still fitted or has been replaced with another differential? |

Re: Locking differential option on my Blazer
1975 K5 Cheyenne !! its had lots done to it over the years, (some of it even good), so i can't be sure the rear diff isn't replaced anyway. What would I look for??

Re: Locking differential option on my Blazer
Here's a pic. They break pretty easily if you spin the tires much.

Re: Locking differential option on my Blazer
I assume that there were different available ratios on these? My SPID states 3.73 Ratio.
