Great product! Works as it should. Can't really say if quality is better than others. They are all pretty close to the same. I have used different brands before, but the crank bearings have never been the point of failure for me to split the engine cases. I always but new ones in if I have them open.
Perfect fit, install is easy when done properly. Put bearing in freezer overnight, heated case in oven, dropped right in! Can't verify performance or longevity but have no doubts.
So far no issues after 20 hours on the new bottom end and bearings, only time will tell but I've used these before on other bikes and had no quality issues.
I just recently had to rebuild my whole motor from the bottom up and put a hour meter on from when I first started the bike...bike ran awesome..put 8.4 hours on the new motor and the BEARINGS fell apart..never again will I ever buy HOT RODS BEARINGS

i do 10 hours of riding in a weekend, Engine was fresh and this thing shattered putting metal all through my rebuilt engine. Used this bearing to save 20$, now I am going to be another 10 hours fixing this right instead of just using quality bearings the first time. Please learn from my mistakes and don't buy hot rods products, almost everything I have purchased from them has prematurely broken, this has been my last straw and I will never purchase hot rods products again.

All bearings are not created equal. I was actually impressed with the hot rods crank bearing kit. They arrived with some grease already applied, which is good in my book. Install was easy, fit was perfect. It's been almost 2 years since I installed. I recently checked end play of the crank when I had a flywheel go bad. (Bad magnets) I thought maybe the crank was bent out of spec which could have caused the flywheel to contact the stator. Anyway crank end play was well within spec. So these bearings held up even thru an unbalanced flywheel. Will buy again!

Never had any problems. Very high quality just coat outer race with grease put in the freezer for a hour or two heat up the case with a propane torch around where the main bearing sits and they slide right in and also make sure the side with the numbers and letters is facing towards the center of the crankcase. Use in all my machines

Replaced OEM with Hot Rods and am very satisfied. Just followed the Honda manual for the rebuild, and everything fit just right. No additional adjustments or shims needed. So far it has served well and have five hare-scramble races on it. Power is consistent and runs great.
<br>Used this kit with the replacement crank and rod. Fits perfectly. You will need a press to remove and install the new bearings. Quality seemed to be that of OEM and have five races on mine so far with any problems. I would definitely use these products again.
