Hummmm, I know of bearing buddies and have used them on rare occasions before, but maybe the TP wheels would be a good candidate for them... When I bought my TP, I bought a "demo" version so I'm not sure exactly what it went thru during it's life cycle at Tow Pac... I had to change both races and bearings when I first did them so I keep an extra set of bearings and races in the cabinet just in case... Only takes an hour or two to change everything out so why not eh?? I just started using the Bel-Ray waterproof grease so we'll see how that works out...
I have been chasing a problem whereby my fenders vibrate violently above 70MPH and haven't found the answer yet... Going to play with tire pressures and wheel balance although I have tried normal wheel balancing and also Centramatic balancers without any success... I normally run my 12" tires around 32PSI but I'm going to try and increase the pressure to see if that makes a difference... It's usually not a problem for me as I don't run that fast normally but it's nice to have the extra speed just in case I have to jump on the Interstate... My tire down force seems reasonable and I don't want to increase it to the point where the main rear tire begins to lose traction so a bit of playing will be involved...
My kit is pretty well dialed in and I've had it for nearly 5 years now and have approximately 20-25K miles on it or so but I continue to try and make improvements on it as time goes by...
I also haul my TP equipped bike in the back of my truck on a Rampage lift and have made the fenders "quick disconnect" (using captive 1/4-20 nuts) to accommodate quick loading and unloading of the bike, as the trike will not clear my truck bed walls with the fenders on... Here is a pic of the trike in the back of my F-250SD shortbed...
Having ridden for the last 50 years or so in all kinds of weather, I have nothing to prove anymore, and these days the bride and I ride in comfort and unload the trike when we get to destination... We'll be heading to the west coast in 2018 to visit Sequoia, Napa Wine Country and points west...
