## Customer Reviews

### ⭐⭐⭐⭐⭐ 4:11 Gear kit
*by T***X on October 10, 2022*

The 4:11 fits great only issue I had was the bearings was a little too small for the posi unit which was a summit racing brand

### ⭐⭐⭐⭐⭐ Look great
*by A***R on July 25, 2022*

Just having them installed

### ⭐⭐⭐⭐ Make sure it is the 8.5!!!!!
*by V***S on June 30, 2021*

It came great and all, packaging was great, the quality seems good. Make sure you verify whether it is a 8.5 or 8.6!!!! Shims matter!!!! I made the mistake of ordering a 8.5 and now I have to fork over 30$ for new shims. Also consider buying more lock-tite if you undo the Ring and Carrier more than once. So far the rebuild process is okay, nothing against the company, we’ll see how it performs this month though!
