2004-2014 Lamborghini Gallardo Bumper Impact Absorber Guide
This guide covers the crucial, one-time-use bumper impact absorbers for all 2004-2014 Lamborghini Gallardo models, explaining compatibility and inspection.
- Bumper impact absorbers are one-time-use safety parts; they must be replaced if they have been compressed in an impact.
- There is a major compatibility split between pre-facelift (2004-2008) and facelift/LP models (2009-2014).
- When buying used, inspect the part for any signs of crushing, cracks, or deformation. It must be in perfect, undamaged condition.
- Replacement requires removing the entire bumper cover, a job that is feasible for a DIYer but requires care and patience.
Known Issues and Symptoms of Failure
A bumper impact absorber does not fail like a mechanical or electrical part. Its failure is exclusively the result of physical damage from a collision. There are no check engine lights or fault codes associated with this part.
- Visible Damage After Impact: The most obvious sign of failure is any visible deformation, cracking, or compression of the absorber after the bumper cover has been removed following an accident.
- Poor Bumper Cover Fitment: If a bumper cover appears loose, sagging, or doesn't align correctly with the fenders and hood, it could indicate a broken, missing, or improperly installed impact absorber underneath.
- Rattling Noises: Pieces of a broken impact absorber can become dislodged and rattle inside the bumper cover, especially when driving over bumps.
Warning: An impact absorber is a one-time-use safety device. If it has been compressed, crushed, or damaged in any way, it has done its job and cannot be reused. Installing a damaged absorber offers significantly reduced or no protection in a future collision.
Vehicle Fitment and Part Variants
The Lamborghini Gallardo was produced for a decade, with a significant update in 2009. This created a split in parts compatibility, including the bumper absorbers.
- Pre-Facelift (2004-2008): These first-generation Gallardos use a specific set of impact absorbers for the front and rear.
- Facelift / LP Models (2009-2014): The updated models (LP550, LP560, LP570) feature different front and rear bumper designs, which require different impact absorbers.
The provided OEM part number, 400813757, is identified in listings as a rear lower bumper bracket or support for a pre-facelift 2008 Gallardo Spyder. It is 🎬 Watch: Pre-LP Gallardo bumper removal and exhaust install crucial to verify the exact part number for your vehicle's specific year, model (coupe/spyder), and location (front/rear) before purchasing.
Pro Tip: When searching for this part, use terms like "bumper reinforcement," "crash bar," or "bumper support rail" in addition to "impact absorber," as the naming can be inconsistent across suppliers.
Buying a Used Bumper Impact Absorber
Given the high cost of new OEM Lamborghini parts, a used impact absorber from a reputable recycler is a smart choice, provided it is in perfect condition. A used absorber that was never in a collision is functionally identical to a new one.
What to Inspect:
- No Signs of Compression: Carefully examine the entire part, especially the corners and mounting points. Look for any signs of crushing, wrinkles in the material, or areas that look compacted. A foam absorber should have a uniform, smooth surface.
- No Cracks or Fractures: Check for any cracks, especially around the mounting holes. Stress fractures can compromise the part's ability to absorb an impact correctly.
- Verify Donor Vehicle History: If possible, confirm the part came from a vehicle that was not involved in a collision in that area. For example, a rear impact absorber from a car with front-end damage is a safe bet.
- Match Part Numbers: The safest way to ensure compatibility is to match the OEM part number from your old part to the used one you are buying. Due to the differences between pre-facelift and LP models, visual comparison is not enough.
Replacement Information
Replacing the bumper impact absorber requires the complete removal of the front or rear bumper cover. This is a moderately complex job that requires care to avoid damaging the fragile paint and plastic tabs.
The general process involves:
- Lifting the vehicle or using a jack and jack stands for access.
- Removing the rear wheels to access fender liner screws.
- Removing numerous screws and bolts inside the wheel wells, underneath the car, and in the engine bay or trunk area that secure the bumper cover.
- Disconnecting any electrical connectors for license plate lights, parking sensors, or side markers before fully removing the bumper.
- Once the bumper cover is off, the impact absorber is typically held on by a few bolts and can be easily unbolted and replaced.
While the process is straightforward, the number of fasteners and the fragility of Lamborghini parts mean it should be approached with patience. A first-time removal can take 🎬 See this video walkthrough of the bumper removal around an hour or more.

Frequently Asked Questions
Can I reuse my bumper impact absorber after a minor accident?
No. Even a minor impact can compress the material and compromise its structural integrity. These parts are designed for a single impact. Reusing a damaged absorber provides a false sense of security and will not protect your vehicle in a subsequent collision.
Is the front impact absorber the same as the rear?
No, the front and rear absorbers are different shapes and have unique part numbers. They are not interchangeable.
Will an absorber from a 2006 Gallardo fit my 2010 LP560?
No. The parts are different between the first generation (pre-LP, 2004-2008) and second generation (LP, 2009-2014) models due to the updated bumper designs. You must use the correct part for your specific model year range.
Is this part the same as the metal bumper reinforcement bar?
No. This part is the energy-absorbing foam or plastic structure that often sits between the metal reinforcement bar (rebar) and the plastic bumper cover. Some designs may integrate them, but they are typically separate components. This guide refers to the crushable absorber itself.
