Central Floor Assembly
$2,170.00
- Type: A major structural component that forms the central section of the vehicle’s floor, extending roughly from the firewall/front floor area back towards the rear seat floor, often including the transmission tunnel. As an “assembly,” it comprises multiple welded steel panels and reinforcements that create the floor pan.
- Function: The primary functions of this central floor assembly are critical to the vehicle’s safety, structural integrity, and overall design:
- Structural Backbone: Forms a substantial portion of the vehicle’s unibody structure, providing critical longitudinal and torsional rigidity to the chassis. This rigidity is essential for handling, ride quality, and crash performance.
- Occupant Protection: Designed to resist intrusion and manage energy absorption during side impacts, impacts from below (road debris), and contributing to overall occupant survival space in various crash scenarios.
- Component Mounting Platform: Provides the primary mounting points for the front and rear seats, center console, transmission tunnel components, exhaust system, driveshaft (for RWD/AWD models), fuel lines, brake lines, and various wiring harnesses.
- Noise, Vibration, and Harshness (NVH) Reduction: Helps to isolate the cabin from road noise, vibrations, and harshness originating from the powertrain and suspension.
- Components: Consists of multiple precisely stamped and welded high-strength steel panels, incorporating various ribs, channels, and reinforcements for strength and stiffness. It will have specific cutouts and threaded inserts for mounting other components.
- Location: Forms the main floor of the passenger compartment, running along the underside of the vehicle between the front and rear seat areas, and typically includes the central transmission tunnel.
- Material: Primarily constructed from various grades of high-strength steel (HSS) and Ultra-High Strength Steel (UHSS), strategically placed for optimal crash performance and weight reduction.
- Design: Precisely engineered to integrate seamlessly with the front and rear floor sections, rocker panels, and roof pillars, forming a highly rigid and safe occupant cell while accommodating all necessary underbody components and interior fixtures specific to the Maserati Ghibli.
The Central Floor Assembly, identified by Maserati Part Number 673006044, is an exceptionally fundamental and integral part of your Maserati Ghibli’s unibody structure. This major component forms the very foundation of the passenger compartment, playing an indispensable role in the vehicle’s overall safety, driving dynamics, and structural integrity.
This complex assembly, comprised of multiple precisely engineered and welded steel panels, serves as the vehicle’s central backbone. It provides immense structural rigidity to the chassis, which is paramount for the Maserati Ghibli’s renowned handling characteristics, responsiveness to steering inputs, and controlled ride quality. Without this robust foundation, the vehicle’s dynamic performance would be severely compromised. More critically, the central floor assembly is a vital component of the Ghibli’s passive safety cell. It is meticulously designed to resist intrusion and manage the forces of various impacts, especially during side collisions or impacts from below, thereby safeguarding occupant survival space. It also provides a secure and stable platform for the mounting of the seats, center console, and numerous other interior and underbody components, ensuring their proper function and contributing to the overall quality and quietness of the cabin.
Given its core structural role, the central floor assembly is typically replaced only under very severe circumstances:
- Major Collision Damage: The most common reason for replacement is significant structural damage sustained in a severe collision (e.g., side impact, major underbody impact, or a high-energy frontal/rear impact that causes deformation to the central section). Even if a vehicle appears cosmetically repairable, structural integrity must be restored.
- Severe Corrosion: In rare cases of extreme, unaddressed corrosion (e.g., from prolonged exposure to harsh environmental conditions or extensive salt), the floor pan could become structurally compromised.
Symptoms of a damaged central floor assembly are usually obvious after a major accident and may include visible buckling, tears, or severe deformation of the floor pan, difficulty in fitting interior components, or significant issues with chassis alignment. Replacement of this component is an extremely complex and critical body-in-white repair that demands the highest level of expertise, specialized equipment, and adherence to strict factory repair procedures. It involves extensive cutting, precise measurement, and advanced welding and bonding techniques to ensure the new assembly is seamlessly integrated into the vehicle’s unibody, thereby restoring the Maserati’s original structural rigidity, safety performance, and design integrity.
For your Maserati Ghibli, ensuring the integrity of the Central Floor Assembly (Part Number 673006044) is paramount to the vehicle’s inherent safety, dynamic performance, and long-term structural soundness. Replacing a damaged assembly with a genuine Maserati part and ensuring professional installation according to stringent factory guidelines is an absolute necessity to preserve the engineered excellence and uncompromising quality of your Italian luxury sport sedan.
