Sputhe Positrack=no wobble. Awesome piece of gear. I've done up my front and rear suspension as well but the Positrack had the most dramatic effect on the handling.

 

+1 on the Sputhe Positrack. Pretty sure this is the best way to go on a Dyna.

 

How do you ride? If you are ok with the stock spring rates and suspension(brake dive etc) You don't need anything. If you like to push the speed limit sometimes maybe the front stabilizer. If you like to really push the limits and get crazy then you need suspension upgrades and the sway links. The predator solves an issue with the front mount sagging as well as adding the front side sway link. (good setup) When you're going around a corner fast and you hit a big dip you won't have to compensate and change lines or deal with wobble like you would with stock suspension.

 

I added the Predator mount yesterday, so performance wise I can't provide any feed back yet. When I went to install the mount, I had to raise the motor about 1/4"-1/2" to get the bottom mounting holes to line up, that tells me how much sag I was getting from the stock mount after 55k miles. Main reason I went with the mount is what fxdlx pointed out, the front mount sag and the front side sway link. Seems the True track and the Sputhe fix the latter, but only a new mount could fix the sag. I do plan to try and get a Sputhe or True-Track for the rear mount at some point (if I can find them not as a front/rear set), I'll be replacing the mount at the same time.

 

I like the Sputhe version but any of them should help prevent the rubber mounted drivetrain from sideways motion when pushed hard.

Your riding style determines whether you need this.

By the way, check your drivetrain alignment in both planes when you install a stabilizer.

 

True track comes in a different part number for taller shocks. I wonder exactly what the difference in the unit are and if taller shock affect the positrac in anyway

 

This is true and thats one of the first things they asked when I ordered.

 

Interesting, I hadn't known this... Is it the front or the rear unit that's actually different? Does anyone know what the actual difference is?

 

Looks like the rear is different. It was a different rear bracket.

Interesting. I never noticed this before.
