Redshift makes a new dual piston cam shoe tensioner. Zippers Performance has these.
Had them installed with my new TW 222 cams along with Feuling lifters.

 

Replaced cams on my 09 at 48K, inner had almost no wear & outer 10-15%, others have reported over 90K & no problems with the hydro versions.

 

Do yourself a huge favour and take the cam cover off and inspect them both, you may need to replace them or you may have little wear, I took the cover off of my 05 RG at 25K and had little to no wear....... unless you just want to waste your money and replace them before they need to be?

 

Shadow, the OP has the newer set up. Not the same as yours. But if you have a 99-06 you should listen to Shadow.

 

If he has the hydraulic tensioners then he should have less concern, although I would still be having a look, then he'll know for sure!

 

The reason yours does not wear is the cam chain is a roller chain. It grooves in and then rolls. However at 50K or 8-10 years I would check it for cracks in shoes. Somewhere alone the line the first ones used the same hard tensioners before they went to the softer white ones. Took Harley two tries to get it right. The Hydraulic was just smoke to hide the link chain crap. Insert is yours and how they wear. Note mileage at 90K. Third is mine and they never stop wearing and Harleys SE conversion even leaves the back one with the same link chain. Forth is Harley's SE conversion with hydraulic on a link chain. Another Harley $1500 JOKE down a rat hole.

 

I intend on checking mine every 20k, an easy task, and I would suggest anyone who has a concern about there's do the same, and make whatever repairs or upgrades they wish when they're needed. May be scary to some that HD has this issue, but really, not that much of a disaster if treated as a wear item and checked on a regular basis. Shame its there, but it is what it is, deal with it and ride on.....

 

74000 miles on my 07 and i changed the cams at around 5000 and they were 90% good so i left them in there...will check them at around 120000...

 

Does anyone have any idea why the motor company went from the old reliable single cam with no chains to a Twin Cam design?

 

At 65k miles on my 07, I replaced my tensioners two weeks ago. From the looks of them, I could have gone another 40k miles at least. I purchased the tensioners and gaskets prior to pulling the exhaust and cam cover off. Since I was already there I chose to replace them. Otherwise, they weren't needed.
