Kit for connecting Toyota 1UZ / 3UZ FE engine to DODGE CHALLENGER / CHARGER / HELLCAT ZF 8HP70 / 8HP90 automatic transmission

The kit includes:

-Complete one-piece flywheel made of special lightweight AlZnMg+Ti alloy with the strength of 42CrMo4 steel, designed for a torque of up to 2000Nm. With this flywheel, there is no need for the factory flywheel from the Toyota automatic transmission. The factory flywheel has limited torque capacity and often cracks above 600Nm. The complete flywheel includes an integrated starter ring gear.

-Reducer ring for the converter shaft of the 8HP transmission, depending on the year of production.

-Adapter made of AW7075-T651 aluminum alloy, surpassing the strength of S355 and C45 steel (1.0503)

-Mounting bolts for the flywheel, adapter, and gearbox

Why choose our solutions?

  • For measurements, we use a modern 3D scanner ATOS GOM, which provides high measurement accuracy. The maximum volumetric measurement error is <0.002 mm. Additionally, if the highest measurement accuracy is required, our workshop is equipped with FARO GAUGE ARM measuring arm.
  • For design, we use legal software from Dassault System called Solid Works Professional. Regular annual subscriptions ensure that we always work with the latest software version.
  • In production, we utilize modern CNC machines from DMG MORI, which are regularly inspected and serviced. The machining accuracy is no worse than 0.01 mm, ensuring excellent alignment of gearboxes with engines. According to international ITAR regulations, machines commonly used in the industry cannot have a positioning accuracy greater than 0.006 mm.
  • We use only the highest quality certified materials in our production, such as special aluminum alloys AlZnMg+Ti with titanium additives for flywheel production. These alloys offer the same strength as 42CrMo4 steel while being lighter. Our adapters are made from an aluminum alloy called AW7075-T651, also known as Fortal. This alloy is nearly three times stronger than the popular AW2017 aluminum. We collaborate with suppliers from the EU and the USA for the delivery of strategic materials.
  • We do not import materials or outsource production to Chinese manufacturers.
