I have them. I bought a brand new tensioner assembly and thought why not? WMW/Powerflex claims that the stock bushings will wear out, which I'm not saying they done. Mine were fine. My problem was the "shock absorber" was leaking and making a hell of a mess. My atla tensioner stop was also chattering against the shock and digging into it.
New tensioner, new bushings, tensioner stop wrapped in electiral tape
no problems!!

Yes we see these bushings cracked and falling apart on cars all the time. The good thing is we just replace them with the powerflex tensioner bushings. Otherwise you have to replace the tensioner, so it saves our customers alot cause the tensioner is almost $200.
Wrapping the Alta tensioner stop in electrical tape was a cheap fix for the rattle, interesting.

Well.......
Here are mine after 12,000 miles.
The bushings were installed on a brand new tensioner assembly.
We figured the bushings are actually too stiff, causing early failure of the damper. Then when the damper goes, it pounds at the bushings until they fall apart. Just a theory.........

Powerflex had a bad batch of the raw material, causing the part to "set up" incorrectly.

While it's still on the near future wish list, have you gotten rid of all the bad batches? Assuming any left in stock have all been replaced by Powerflex or was there a certain ID tag to know of the bad production date(s)?

When mine goes, I'll be trying Alta's adjustable tensioner. No need for that wimpy damper, poly bushes & a separate stop anymore. & much cheaper. Works like a turnbuckle. From tests & user reviews.....No more belt slip, tensioner & crank pulley failure from snapped belts....Simple+worry-free + reliable.

FYI we have a new set of tensioner bushings made of delrin

The alta rod is just a fixed bar. It doesn't have give or change tension like the original design so I would not recommend it as the belt will be over tensioned at certain loads and under tensioned at other loads.
