Product Details

The Wiseco 4729PS is a forged 4-stroke piston kit engineered for Harley-Davidson Panhead and Shovelhead Big Twin engines. Featuring a 3.497-inch (3497X) standard bore and a 7:1 compression ratio with a domed piston design, this kit is purpose-built for classic V-twin rebuilds requiring reliable, high-strength performance.

Wiseco pistons are forged from high-silicon aluminum alloy, delivering superior strength and durability over traditional cast alternatives. The precision forging process and optimized piston skirt geometry are designed to maximize horsepower and torque output while maintaining long-term dependability under demanding conditions.

great selection, fast delivery

GREAT !

Great

Our cover came quickly and the quality seems good! Putting it on the boat this weekend!

Super fast delivery. Great first impression.

Product showed up in great condition and relatively fast.

Best price, easy to navigate web page

Simple to the point

Finding the item was great. There were not many places that had it due to stock shortages from Onan/Cummins. The price was a lot lower than the closest company that stocked it. Ordering was easy. However, I contacted CS due to the fact that the "Tracking" link in the email did not lead me to any type of tracking. The only thing it did was go to the invoice for the order. I was kind of bugged as I was getting ready to head out of town and needed the part. I do web app design and implementation for a living. Someone needs to check the click on links to ensure they go to the proper place.
