### ⭐⭐⭐⭐⭐ Great!
*by G***. on July 7, 2025*

Just installed , verry smooth no problem for me , 👍👍

### ⭐⭐⭐⭐⭐ Works fantastic
*by A***. on March 17, 2023*

The media could not be loaded. Pros -it works great off road and in the snow, totally locks the diff up, easy to install. IMPORTANT axle end play specs, set them right!! Wife drives the vehicle and doesn’t notices it. on road works well also.Cons - install manual sucks, clunky at times, hard on tires.It is easy to install. Unfortunately in the Chrysler 9 1/4 diff I installed this on came with Posi case. And the original part I ordered was the one for the Posi case. I didn’t fit, called tech support to verify I had the right part, they were quick to help. Unfortunately I had to order this locker along with new open case $135 new spider gear set $70 “just for the shims” the backlash adjustment tool $25 bearing set $100, fee to get the bearing pressed on $40, and backlash gauge for $30. I installed this on a 1999 Durango 4wd. The installed required a lot more work also had to weld the abs/speed tone ring to the case because when installing the original ring gear to the new open case. The tone ring had enough clearance to spin free. Time consuming and annoy. But the locker works fantastic. On road it’s mildly noticeable clicking around turns and clunky at times. But overall not a big deal, my wife drives the Durango often and has never complained about it.Video upload was with vehicle in 2wd.

### ⭐⭐⭐⭐⭐ It’s a long review but worth a read
*by P***P on November 18, 2023*

Installed in a 8.5 10 bolt open carrier. Went into a c10 with 5.3 4L60 and 275/60/15s. Install was breeze, just go read Motortrends install write up and it’s smooth. I was able to push the springs in the just my fingers and it went fine. I did install with the ring gear on but out of the truck, but doing it while still in the carrier wouldn’t be an issue either. TIPS FOR C CLIP AXLES—Just be patient, work the axles back and forth while holding clips in and you will eventually get the spacers in to cover the clips. I used a knife in the center, it’s a pain in the a..but keep working with it. I used 2.25ish quarts of 80w90 Lucas, I do have turndowns but I heard the clicking a couple times but nothing bad. If you’re around 10ish percent throttle, you may can take a sharp corner while clicking but it could lock halfway through. Again, not bad, I dig it actually. Second, when you let off the throttle, then get back on it, it may feel a little odd..a shimmy maybe but you don’t even have to touch the wheel. It’s not bad at all. If you’re getting this for the street, I strongly recommend just be sure to understand the trade offs ( chirping sometimes, a clunk or two some, clicking) If it’s chirping in a corner, it’s very easy to just throttle up a bit and it’ll spin on up easier than you think. Just don’t fear a locker, get it! I will update if any issues arise.
