ROCKOUT rocker shaft inserts

ROCKOUT rocker shaft inserts solve one of the most annoying problems with the Harley Davidson Twin Cam engine…. that maddening tapping sound that rolls in around 2000-3000 RPM’s & leaves just as quickly as RPMs increase. My research discovered that the noise is caused by the factory’s sloppy fit between the rocker shafts and the hold down bolts meant to keep them in place. The rocker shafts are allowed to side in & out, and rotate, hitting the bolts at high frequency & creating that awful tapping noise. You can see the marks in the hardened bolts from the hammering in the pic above. My inserts fill that gap, locking the shafts in place, stopping the noise.
Tapered for easy installation, professionally made to exacting tolerances so each is virtually identical. Kit includes 4 inserts (and a spare!), 2 Viton O-rings for under the support plates, full instructions & easy installation hardware.

Here’s just one actual review from a customer on the largest online HD forum…

“I had been telling the tech I use at the dealer about the Rockouts. So when I had my bike in there for some work I had him install the Rockouts. The ticking is gone and when the service manager walked by my bike as it was running he stopped and said my bike was the most quiet he had ever heard. Had the tech order some for his bike. In fact I think he said he ordered a set of 10. I have to agree. None of my previous Harleys were this quiet. FWIW I’m running Woods TW 777 cams and the valve train sounds like a well oiled sewing machine.”

Stop that aggravating tapping forever!
