    • Great value on quality parts
Review Image by MikeB MikeB
Not sure why this kit is so inexpensive. It uses quality Koyo bearings made in Japan and the US. The only reason I can see for its low price is the kit was not packed in its original box. However, the seller included the original box end flap showing the USA Standard Gear P/N and description. Score! Just noticed the "YK" kit costs nearly 4 times as much as this "ZK" kit, probably because it uses Timken bearings. Makes no sense to me because Timkens can be made outside of the US, and I don't see how they can be significantly better than a US- or Japanese-made KOYO. And I've read where KOYOs are used in all kinds of Japanese car and truck applications. Maybe someone can enlighten me. ... show more

    • Works great!
These guys are great, superior customer service and quality parts. Thanks so much. This kit works great in a factory GM 8.5" rear for 1998 Tahoe with the GU6/G80 carrier. I had to make some changes and the seller accommodated my needs and helped me out with everything else. Thanks Brydon!
