LAMBORGHINI HURACAN PERFORMANTE LP640 RZR Gearbox Complete

the term “RZR” refers to the specific Transmission/Gearbox Code assigned to certain versions of the Lamborghini Huracán Performante’s 7-speed LDF (Lamborghini Doppia Frizione) dual-clutch system.

While all Huracán gearboxes share the “0BZ” family architecture, the RZR code denotes a specific hardware and software calibration optimized for the Performante’s $640\text{ CV}$ output and the high-performance demands of the Nürburgring-tuned chassis.

1. Technical Identification

• Gearbox Family: 0BZ (DL800)

• Specific Code: RZR

• Part Number: Primarily 0BZ300041 (with suffixes such as N or P).

• Type: 7-Speed Dual-Clutch with integrated front-axle output (PTO).

• Key Difference: The RZR-coded unit features Performante-specific shift maps. In Corsa mode, the “RZR” calibration provides the most aggressive “inertia shift” feel, designed to maximize acceleration at the cost of smoothness.

2. 2026 Market Pricing (Estimated USD)

Because the Performante is a limited-run “hardcore” model, finding a complete, low-mileage RZR gearbox is more difficult and expensive than finding a standard LP610 unit.

3. Compatibility & Swapping

• Standard LP610-4 to Performante: You can physically bolt an RZR gearbox into a standard 610-4, but you will need the Performante Transmission Control Unit (TCU) or a software flash. Without the software match, the car may shift incorrectly or throw a “Torque Mismatch” error.

• AWD Requirement: The RZR is an AWD-specific gearbox. It cannot be used in a RWD (LP580-2) car without removing the front output shaft and potentially reprogramming the electronic differential logic.

4. Critical Components Included in “Complete”

When purchasing a “Complete” gearbox, ensure it includes:

• Mechatronic Unit: The internal computer and solenoid block (the most common failure point).

• Clutch Pack: The dual wet-clutch assembly.

• Internal Oil Pump: Vital for the high-pressure shifts of the LDF system.

• External Oil Cooler Lines: Often cut during salvage removal; check for damage.

5. 2026 Maintenance Checklist for RZR Units

• Clutch Life: Performante units often see more track time. Always request a Clutch Wear Readout (PIWIS/LaRA diagnostic) before purchasing used.

• Gearbox Fluid: Use only the factory-specified Pentosin FFL-4 or the latest 2026 Lamborghini OEM equivalent.

• Launch Count: The “RZR” unit records the number of “Thrust Mode” (Launch Control) starts. A gearbox with over 50–100 launches may require a clutch pack refresh sooner than a highway-driven unit.
