I have the rating I did, because the kit is not what is pictured. It does not have axle seals and it does not include a pinion nut washer. My pinion nut is a lock nut, and uses a flat washer. What is included is a regular nut, without a lock washer. So I have to re use. But overall the kits not too bad. The bearings match up, and koyo is a good reputable name. I do recommend buying a cross pin bolt. They are just a few bucks, and if you ever need to get back in you don’t want it to break. It fit my GM 8.6 rear end nicely.

This is a great budget installation kit. The KOYO bearings are probably not quite as good as Timken, bbut for a budget kit they are great. The shims in the USA Standard kits are much better than other kits.

This item was EXACTLY as described. Due to Amazon guidelines, I am unable to share any other information about my experience.

Fit my 01′ Suburban fine. The nut is a lock nut. It has a stake mark on one of the flat spots. Keep in mind that there aren’t any shims or axle seals. Enjoy

Decent kit- working fine so far in my 8.6″ GM rear end. Hopefully lasts me many more years. Didn’t use the gasket- bought a new cover and it came with a much higher quality gasket. Bearings fit and seem good.
