Not sure you'd need both but that would be one tight azze end, Mstng5. The Sta-bo isolator "helpers" would prevent damage to the OEM isolators caused by the torque of the Progressive Link I'm betting and be a good thing. You would most definitely notice a vibration change as everything is now tied together tighter but not a bad trade off for a bike on a rail.
I have the Glide Pro set up on my '91 and it is heavenly compared to that swishing azze end it used to have and it is noticeable at all speeds.

There is no point fixing something twice! I can't see any benefit in using two of these products on the same bike, so save your money.

Mr.Brown,I always read your interesting posts and I think you might have a point here,it definitely would be overkill but my question is:would the use of both cause any unwanted reaction to the bike behavior or even damage or just make the bike feel "tighter"?Thanks

That's a difficult one! I suspect that one of them would end up doing most of the work, with the other one not contributing much. A True-Track stabilizer, for example, is adjustable and needs to be set just right, while the Sta-bo stabilizer is not adjustable. Sta-bo do however sell improved swingarm bushings that are worth considering and which should tighten up your swingarm, although True-Track also offer alternative bushings in their Trackula kit.
I really can't imagine any way in which using two stabilizers will make your bike feel any tighter. You have to bear in mind that every Buell and all rubber-mount Sportsters have a rear stabilizer similar to a TT kit and they are just fine (I have one of each!).
So many options.....

I deffiantly dont disagree with you. I plan to put the sta-bo bushings in my bike soon, as the "fix" seems like the best option in my opinion. But if the "fix" helped minimize unwanted deflection. This is the whole reason for the rear steer in the first place. Wouldnt the stabilizer help even more and prevent these bushings from deflecting at all? Then the bushings could just be a piviot point that they are designed to be, and the stabilzer bar could take all the force that causes this whole mess in the first place. I guess you could say the bushings are what harley should have done in the first place. And adding the stabilizer and adjusting it properly should just make it that much better. The only problem i could see with it would be added vibration. More or less just some food for thought.

Later spec swingarm bushings are reasonably OK. The main problem lies with the rear rubber mounts and the lack of a rear stabilizer. The True-Track addresses that problem and does not in my experience introduce any vibration. There are alternative designs out there, but I can see no benefit in using more than one of them!

This thread has got me thinking ( no small feat 
) and I'm thinking Sta-bo isolators AND the Progressive Link would be an ideal setup as one would compliment the other. It would be replacing/fixing the weak isolator AND tieing the whole engine/tranny assy. to the frame in the rear where the stabilizer is now missing. Hmm.
Plus you could do them both for the cost of one under carriage stabilizer assy and not affect ground clearance.

call Kevin at Sta Bo. He is a great guy, knows his product well and will not steer you wrong. I live about 5 miles from him and he has really helped the handling on my older bike. Both the bushings and the bearing are great products.
