I have never done this as a premptive strike. But, it is not a bad idea. All 3 of my TTs have ended up with upgraded running gear, due to the stock stuff failing.
Hard to say what you should do.. A lot probably depends on how often you use it, and how hard.
I will say that the stock stuff needs to be babied.
I too give a thumbs up to the shock absorbing equalizers made by Dexter and Lippert. They both operate under the same principle and both get good reviews. They are of course a wear item, but last a good long time.
If doing this. there are some differences in measurements and ratings between the two brands, so pay attention to that. All else being equal, buy the ones that are the cheapest,
I have run the wet bolts, and though they are an upgrade, I now run the Lippert Never Fail bushings. I like them a lot better. No greasing and they last a long time.
Want the very best? Get the MorRyde setup with disc brakes. Not cheap.
Personally, I would just upgrade as needed due to failures. You may not have the TT long enough to make it worth while upgrading as a prevenative measure.
Your money, your choice.
