Lamborghini Aventador FRONT Frame

the Front Frame of the Lamborghini Aventador is a critical structural component made of high-strength extruded aluminum.

While the passenger cell (the “tub”) of the Aventador is a carbon fiber monocoque, the front and rear frames are aluminum sub-structures that bolt directly to that tub. These frames house the suspension mounting points, the front differential, and the cooling systems.

1. Technical Identification

• Primary Part Number: 470803011 (Base code for the Front Subframe Assembly).

• Material: Aluminum Alloy (Extruded and Cast sections).

• Construction: It is designed as a “sacrificial” structure. In a front-end collision, the aluminum frame is engineered to crumple and absorb energy, protecting the expensive carbon fiber monocoque.

• Compatibility: While the core geometry is similar across the line, the SVJ and Ultimae frames have specific reinforcements for the active aerodynamics (ALA 2.0) and revised suspension geometry.

2. 2026 Market Pricing (Estimated USD)

Replacing a front frame is almost always the result of accident damage. Because it is a major structural part, shipping costs are high and the part itself is expensive.

3. Repair vs. Replacement

• The “Zero Tolerance” Rule: Lamborghini strictly forbids the straightening of aluminum frames. Aluminum “remembers” stress; if it is bent and pulled back, the molecular structure is weakened.

• Inspection: In 2026, most insurance adjusters will insist on a 3D Laser Measurement (such as a Celette or Car-O-Liner system) to verify if the frame is within factory tolerances (usually $+/- 1.0\text{ mm}$). If it’s outside this, replacement is mandatory for safety.

• Corrosion: On older LP700 models, check the mounting points where the aluminum meets the carbon tub. Galvanic corrosion can occur if the specialized isolation washers have failed.

4. Critical Installation Notes

• Single-Use Bolts: The bolts that connect the aluminum frame to the carbon monocoque are stretch bolts (torque-to-yield). They must never be reused. Reusing these bolts can lead to the frame shifting under heavy braking or cornering loads.

• Alignment: Once the frame is replaced, a full “Chassis Setup” is required. This goes beyond a simple wheel alignment; it involves checking the ride height and corner weights to ensure the car’s high-speed stability is restored.

• Drivetrain Removal: To replace the front frame, the front differential, steering rack, and radiators must be removed. This is a 30–40 hour labor job.

5. 2026 Salvage Warning

If purchasing a used frame, ensure it comes with a Certificate of Straightness. Many frames on the secondary market are pulled from cars that were “totaled.” Even if they look straight to the naked eye, a 1mm twist in a suspension mounting point will make the car impossible to align correctly, leading to “darty” handling at high speeds.
