For owner's not familiar with us and our support of Graziano gearboxes, we have put together a brief overview to describe.

HCF Autosport is the Graziano factory distributor for the North American market. We support the entire range of Graziano's gearbox platforms that were OE fitment in various Aston Martin, Lamborghini, Ferrari and Audi vehicles. Specific to the platforms on GT40s, the Graziano L140 gearbox from the Lamborghini Gallardo and first generation Audi R8 has been a popular choice for their torque capacity, parts availability and attractive overall cost.

We specialize in the support of this gearbox and have a full range of products to support all applications and desired output levels. This includes:

- Clutches in multiple formats to support up to "3,000hp" - https://hcfautoparts.com/clutch-conventional
- Drop gears to support a wide variety of top speed targets - https://hcfautoparts.com/graziano-l140-products
- Full replacement internals in a motorsports alloy to support "1000lbft" and an aerospace alloy to support "2000lbft"
- Sequential paddle shift conversions that can allow the car to operate in automatic mode, if desired - https://hcfautoparts.com/paddle-shift-conversion
- Midplate and retaining plate upgrades to support higher torque in an otherwise factory gearbox
- Overdrive 5/6 gears for use with lower-revving American V8 engine's
- High torque and motorsports tunable ramp & plate-style limited slip differential upgrades
- Custom axles
- OEM replacement components direct from the factory
