Nitro Gear Install Kit came with ILJIN Carrier Bearings - Any Good?

[BAR]

I purchased install kits from Nitro for installing 4.88s. Their website states that "The kits assembled by Nitro Gear and Axle only use the highest quality bearings available from Timken and Koyo." However, the kit came with a mix of Koyo, Nachi, NSK and ILJIN bearings. I am fine with the Koyo, Nachi and NSK since that are all well known Japanese manufacturers. However, the rear carrier bearings are the ILJIN bearings. I am not familiar with ILJIN and can't find much on their quality. Anyone used ILJIN before or had experiences (good or bad) with their bearings?

Thanks in advance for the input.
