Parts seem as good as oem and have held up perfect since i installed them around 2 months ago. I have only one negative regarding the wheel replacements, but it’s an easy fix.

Get about a 2-3 foot 1/2 inch dowel or a sturdy stick to pry the idler back so you can get the belt around the motor pulley. The fix is to purchase m10 hex nuts that fit the threading. Tensioner is ball bearing upgrade vs the original sleeve roller.

There were seam bulges from the molding process on the rubber as well. They ride on a pin with a metal insert sleeve (bushing) and don't have bearings. Other rollers have significant wear already.

Save the headache and spend an extra $10 on a different kit. Going to try genuine samsung parts- these are very poor quality.
