Yes, I just installed them on my truck. Side-by-side I can see why this new style tubular seal (like a "sock") is superior to the stock setup. It has a larger sealing surface, sits at a different location on the driveshaft (compared to where the stock seal has already worn a very slight groove) and is super flexible when t comes to driveshaft movements. Buying them already set in the retainer eliminates one round of pressing stuff in and out and one less chance to damage a seal. I am usually quiet about endorsing stuff, but their axle boots and upgraded inner seals need to be highlighted as high quality products. Plus, they are USA made and not NewStar from Asia.
