  • Ultragram AT A GLANCE...

  • The ULTRAGRAM is Konig’s NEWEST Flow Formed wheel and is the result of the most technology we’ve ever put into any wheel! We’ve taken every ounce of feedback we’ve received from all of our high level race programs to develop a wheel that will offer the most amount of longevity and rigidity all while offering an amazing weight savings. The ULTRAGRAM has 7-spoke, motorsport inspired design that is built with flow forming technology. The Ultragram has a knurl bead seat to prevent tire slippage for high-torque motorsports applications. Offered in both, Titanium Metallic and Carbon Bronze Metallic finishes and sizing in 15×7, 15×8, 15×9, 17×8, 17×9, 18×8.5, 18×9.5A, 18×9.5B (select fitments), 18×10.5B, 18x11B with high and low offsets available.

    **Carbon Bronze Metallic is primarily a darker graphite with bronze undertone**

    • What is Flow Forming?

      Flow Forming Technology involves the application of pressure to the inner barrel of the wheel, while spinning & after it has been casted. This process shares similarities to that found in the forging process in which the aluminum molecules are compressed resulting in a lighter & stronger wheel with greater shock resistance & elongation properties.

    • The process of flow forming starts out with a precisely casted wheel that’s narrower then its final width.

    • The wheel is spun under heat while applying pressure to the inner wheel.

    • The end result has arrived to it’s desired width & is now stronger, lighter & shares properties of that of a forged wheel.
