    these are fairly new and most people that bought them probably have not installed them yet. i know some that have them on the bench to be installed and waiting for spring, i know 1 person using it with a high boost wheel and all is good so far if not i would have got that ( i destroyed my SC ) phone call. lol.
    if they turn out to be bad youll hear about it here real quick, sometimes no news is good news.

    I'm trying to figure out which shaft to get for my ET 15.5. Is the hydraulic bearing on the Gen3 really that big of an upgrade? I was really leaning towards the R&D.

    Absolutely! This is an ingenious design and will most definitely improve reliability.

    Hydraulic end bearing and one-piece shaft bearing are fed by a through-shaft oiling system providing superior lubrication. Oil is delivered by braided stainless line and injected into a billet end cap that houses hydraulic bearing. Shaft is precision machined from a single piece of high-strength billet steel producing shaft, collar & gear as one piece. This eliminates the common failure point on stock shafts where OEM gear is pressed onto shaft. Shaft also features larger diameter threads & nut for added strength. Kit includes new one piece bearing with increased surface area providing improved torsional stability of shaft. Bearing features superior materials & finish treatment for reduced friction & abrasion resistance.

    Does the durability increase from having the pressure lubrication, outweigh the loss in strength from having the shaft drilled out?

    It far outweighs it. I know of several race teams using this shaft and nobody is breaking them. The hydraulic bearing in the Riva GEN 3 shaft stabilizes the end of shaft which limits torsional deflection. Torsional deflection is what causes high boost SC impellers to touch down on the housing. The Riva shafts internal oil passages improve lubrication to the bearings. Deans Team had great success with these shafts along with the Riva dampener on 2011 national tour running lots of boost

    I have it . . used it ... and now back to the gen 2 shaft .... only because I tend to change chargers so often ... it's a must with the high boost wheels (ex ET 1 but Since I run an ET low boost the majority of the time .. I went back to the gen 2 shaft (because it was already installed in the charger)
