Designed using leading-edge Solidworks 3D CAD & Cosmos FEA software
- Flywheels can be customised to our clients' exact dimensions and design requirements
Precision Balanced to over 12000rpm
- Ensures the utmost reliability from our Lightweight Flywheels, which are specifically designed to reduce weight and inertia for improved engine response and acceleration
Manufacture
- Made from imported Japanese SAE 4140 Steel
- All OZ Performance Drivetrain flywheels are Forged. We do not use inferior Cast or Billet processes
- Forged components are upto 30% stronger & tougher than the equivalent 'Billet' component
- Advanced material processing, heat treatment & finishing techniques offer superior strength, durability and quality
- Primary Heat Treatment: After the forged parts come off the press, they are Normalized and Annealed to relieve residual stresses and make them machine workable
- Machining: After the forged blanks are completed, we use Industry-leading Multi-Axis Kashifuji and Mitsubishi CNC/CAM equipment to machine the parts
- Secondary Heat Treatment: State-of-the-art Case Hardening procedure achieved via computer-controlled Gas Carburization and Quenching
- Double-Tempering: A superior heat treatment technique used to decrease the brittleness and increase the toughness of our parts
- Surface Grinding: Through the use of our state-of-the-art Klingelnberg grinding machines, we ensure all parts are smooth, precise, and free of burrs
- Cryogenic Tempering: An advanced treatment technique whereby the parts are cryogenically hardened at -185°C, realigning the steel's crystalline structure for maximum strength, then heat tempered again for a 3rd time to ensure maximum toughness (resistance to fracture)
- Proprietary Nitride surface treatment for increased surface hardness
Quality Control
- ISO Regulated, multi-level quality control procedures ensure only the best products
- Designed and Manufactured to the latest AGMA gear standards
- State-of-the-art TESA, Zeiss Contura, Klingelnberg P40 and Osaka Seimitsu Kikai CMM's (Coordinate Measuring Machine) for extreme precision
- Strict Test Protocols, including advanced microscopy inspections, ensure the OZ Difference
At OZ Performance Drivetrain, we are proud to design & manufacture the most technologically advanced drivetrain products on the market. As a full-service R&D company, we
do not deal directly with the public. All designs are proprietary and are subject to minimum order quantities (MOQ).
As all flywheels are customised to the clients' requirements, production is subject to a
50pc MOQ per fitment.
