GREAT SELLER!!!
This is not actually a review of the item purchased. It was a car part. It is installed and the truck back together and running fine. This seller is AMAZING. We originally ordered the wrong part. When we called they were so very helpful and intent in getting us the right part. Down to counting cogs on gears. The return was easy and hassle free. They shipped the new part promptly. We cannot Thank them enough.

3 1/2 weeks gears completely gave out
Product arrived packaged good, easy install on my 84 elcamino, almost a month later me my an her daughter was about 190 miles away from home and without any warning at all the gears just completely went out, stranding us for about 2 days and I just found out the warranty is good for 30 days only so yeah I'm out that money also 🤬👹 Vary disappointed with this product an I buy a lot of merch from Amazon but might be switching to a different outfit this little episode costed me a good chunk of change 🤔😤💩🔥

Perfect fit and good quality
Fit perfectly in the Dana 35 rear axle on my 2004 Grand Cherokee. Looks like good quality gears. I installed the same spider gears in my 93 Wrangler (YJ) last year and they are still working good. Can't beat the price.

Excellent Price. Excellent Fit. Good Quality.
I ordered these gears because research indicated that they were Yukon Gears that didn't qualify for "Quiet Gears". Maybe they weren't smooth enough - I don't know. They appeared good quality, installed nicely, and I did not notice any additional noise coming from the back end (97 Wrangler, 224K miles). Received on time and quickly. I will update if there ends up being an issue with the gears. So far, very satisfied.

Comes with new shims.
I had already purchased the spider gears elsewhere, but they did not come with new shims. When I noticed that my side gear splines were very worn I knew I needed to get this complete kit. I now have an extra set of new spiders that I removed when I installed this full kit. Came with new shims for both the side and spider gears. The new side gears sure fit snug compared to the old worn out gears. For good measure I also replaced the axles with a set that had better splines. Wow, no more metallic clunk noises and it is tight like a new diff.

Excellent Spider Gear Set
Perfect fit, machining looked good and they all slipped into place nicely. Everything needed was included in the kit. Used in a 60’s Ford 8”.
