Excellent quality
Great quality. Perfect fit. The bigger bearing on the inside makes it a superior hub from stock.

Very nice upgrade. Quality part
Very nice quality product. Replaced my broken wheel hub with these. I go bashing alot but these holds up fine with the beating. Would recommend it.

High quality parts, mean less downtime for repairs!
These things are life savers. I kept breaking the stock plastic ones on my Kraton. These are definitely withstanding everything I can through at it. I love to do back flips off a ramp I built and sometimes it comes down hard on the front end when it doesn't get quite all the way around, no issues. I've got one other hot racing part in this truck, and based on their quality, if I could afford it I'd swap everything for their parts. Extremely happy with the purchase.

Almost unbreakable. No problems after 3 months
I kept breaking the stock ones about once a week so when I went on a $700 spending spree on kraton upgrades from hot racing, yeah racing, rpm, gpm, integy these were one of the first upgrades I did months ago and haven't had a single problem since. Just remember that the inner bearings are bigger than stock so the bearing packages for the kraton will have the smaller size that doesnt fit. I get new ones from uxcell, $8 for 5 ABEC 3 15x24x5, they last about 2 months with daily use and hard bashing. Haven't been able to find abec5 15x24x5 for a decent price anywhere or really any at all.

Arrma steering knuckles
Great upgrade to the stock steering knuckles. I needed them after sending it hard at the skate park and breaking the plastic stock ones. Arrma is the best!!!

Great product
Perfect fit for the 2019 Kraton 6S V4. Aluminum parts hold up much better than stock plastic ones. The delrin oring helps keep the hub nut in and overall this thing is strong. Wi definitely buy again, if I ever need to.
