Product Details

The Wiseco 6634M89 is a Pro Tru Sport Compact Series forged replacement piston, engineered for high-performance street and competition applications. Built on Wiseco's decades of race-winning piston development, the Pro Tru line delivers premium forged quality at exceptional value.

Manufactured in Ohio by skilled craftsmen using dedicated forgings, state-of-the-art forging presses, and CNC machining, Pro Tru pistons are stronger and lighter than industry-standard cast or hypereutectic alternatives. Dedicated forgings specific to each final piston shape ensure superior material grain structure and dimensional accuracy.

Key Features:

  • American-made forged construction for superior strength and reduced weight
  • CNC-machined from dedicated, application-specific forgings
  • Includes plasma moly ring package — pre-gapped 1/16", 1/16", 3/16" rings for excellent seal, friction reduction, and long service life
  • Wrist pin included
  • Available in multiple volume options to achieve a precise target compression ratio
  • Recommended ring set: 8900XX
  • Part of the proven Sport Compact Pro Tru lineup trusted by engine builders worldwide

Whether building a street performance engine or a dedicated competition powerplant, the Wiseco Pro Tru 6634M89 gives engine builders the forged quality and compression ratio flexibility needed to optimize power output and durability.

I placed an order on Monday & received product on Saturday. I am very pleased with the turn around time & the price. They had the best price on the internet that I found and they were helpful to work with.

Timing gearset arrived in under 48 hrs! Gears look well made. Can't wait to get them on my car. Thanks for the great service!

Great prices! Should look to a search engine similar to summit though

Product was shipped super fast. And product was in a well packaged box and everything was there. I would do business with them again in the future. Highly recommended and lowest prices!!!
