I CANNOT BELIEVE THE DIFFERANCE THIS MADE ON MY HIGH MILAGE OBS. OLD DAMPER WAS WABBLING A LITTLE, NOT BAD BUT I WAS GOING TO DO MY LPOP SO IT WAS TIME. SPRUNG FOR THIS EVEN THOUGH IT MIGHT HAVE BEEN OVERKILL.. I DONT CARE WHAT IT COSTS, THIS THING IS WORTH ITS WEIGHT IN GOLD. MY 7.3 IDILES AS SMOOTH AS A GASSER NOW, AND QUIET. ITS BUTTER THROUGH THE ENTIRE RPM BAND NOW. I WAS GETTING SOME INTERESTING VIBRATION IN THE HIGHER RPM'S BEFORE BUT NOT ANY MORE! NIGHT AND DAY IMPROVEMENT, ALMOST FEELS LIKE A WHOLE NEW ENGINE. THIS SHOULD HAVE BEEN THE FIRST THING I DID TO MY ENGINE. DONT HESITATE, THESE ARE AN INVESTMENT IN ENGINE LONGEVITY BY HOW MUCH THEY REDUCE INTERNAL VIBRATION COMPARED TO THE OEM- THERE BY REDUCING WEAR. THANKS CLAY!

These guys are great at Riff Raff diesel. Clay is always helpful, and returns calls. These days that's a tall order! I installed the fluid damper and while I don't sense much difference vs the stock harmonic balancer at idle , the real magic happens at high RPM. Great product, and worth the cost to ensure more stability , and longevity. Thank you Riff Raff diesel !!

This harmonic balancer is a quality product and does what it says. Definitely smoothens out idle

Clay is great to deal with. Install was easy and there was a instant change in how smooth the engine idled and a difference cruising down the road.
Thanks again Clay
