Duraflex Body Kits: Building a Complete Custom Exterior
23rd Sep 2026

A vehicle's exterior can completely change the character of a build.
The right bumper can transform the front end. Wider fenders can change the stance. Side skirts can visually lower the car, while a rear diffuser or spoiler can complete the design.
Duraflex has built its catalog around exactly this type of transformation, offering a huge range of aftermarket exterior components for enthusiasts who want to move beyond factory styling.
At XPH, the Duraflex collection includes complete body kits as well as individual bumpers, fenders, fender flares, hoods, side skirts, spoilers, lips, diffusers, and other exterior components. Current Duraflex applications cover everything from BMW and Mercedes-Benz to Ford, Dodge, Chevrolet, and other platforms.
More Than a Complete Body Kit
When people think about Duraflex, complete body kits are usually the first thing that comes to mind.
But a full kit is only one way to approach an exterior build.
The XPH catalog includes individual components that can be used to change specific areas of a vehicle without replacing the entire exterior. That makes it possible to approach a project gradually.
A build might start with:
- a front bumper or lip
- side skirts
- rear bumper or diffuser
- replacement fenders
- fender flares
- a hood
- a trunk spoiler or wing
- custom air vents or exterior accessories
This gives enthusiasts the freedom to create a complete transformation or concentrate on one part of the vehicle at a time.
Duraflex Construction
A major part of the brand's identity is its fiberglass-based construction.
Current XPH Duraflex products commonly use hand-laid 6 oz. fiberglass combined with a proprietary polymer blend designed to provide greater flexibility and impact resistance than conventional fiberglass components.
The material approach is intended to provide a balance between weight, strength, flexibility, and durability.
Many products are supplied with Duraflex's characteristic black finish, providing a surface that can be prepared for the final paint and bodywork process.
That last part is important.
These are aftermarket composite body components, not factory-painted replacement panels.
The Importance of Proper Preparation
One of the biggest differences between installing an exterior performance component and simply bolting on a mechanical part is the finishing process.
Duraflex itself emphasizes that fiberglass body components require careful preparation before achieving a show-quality finish. Sanding, filling imperfections, block sanding, priming, test fitting, and painting can all be part of the process.
The exact amount of preparation depends on the individual component and the vehicle.
For that reason, professional installation is strongly recommended for many Duraflex products. XPH product listings likewise note that test fitting, sanding, trimming, filling, drilling, and painting may be required depending on the application.
The extra preparation should not be viewed as a drawback of the concept.
It is part of building a genuinely customized exterior.
Start With the Vehicle's Overall Shape
A common mistake when building a custom exterior is choosing individual parts without considering how they interact.
A large front bumper can look disconnected from narrow factory fenders. Aggressive fender flares can require a wheel and tire setup that matches the additional width. A large rear wing may need other exterior changes to make the overall design feel intentional.
Duraflex offers enough variety to build around the vehicle as a whole.
The objective is not simply to add the largest possible component.
It is to create a consistent visual relationship between the front, sides, rear, and overall stance of the vehicle.
Widebody Styling and Fender Flares
For enthusiasts looking to change the stance of a vehicle, Duraflex offers an extensive selection of fender flares and widebody-style components.
The current catalog includes applications such as the BMW 2 Series F22/F23, Dodge Challenger, Dodge Durango, Ford F-150, Ford Fusion, and numerous other vehicles.
These components can create additional visual width and make a vehicle appear substantially more aggressive.
Some are also designed around wider wheel and tire configurations.
For example, the Duraflex MHR front fender flares for the 2014–2021 BMW F22/F23 are specifically intended for M Sport models and are designed to create a wider stance while accommodating wider wheel and tire setups.
The important consideration is that wider exterior components should be planned together with the wheels, tires, suspension, and desired ride height.
Bumpers That Change the Front and Rear Profiles
Bumpers are among the most visually significant components of an exterior build.
Changing the front bumper can completely alter the vehicle's proportions, while a matching rear bumper can make the transformation feel factory-integrated rather than pieced together.
Duraflex offers numerous bumper designs inspired by different performance styles.
The XPH catalog, for example, includes a 1M-inspired front bumper for the BMW 6 Series F06/F12/F13 and performance-oriented bumper designs for a wide range of other vehicles.
Depending on the design, these components can also incorporate grille openings, mesh, ducts, or modified aerodynamic surfaces.
Side Skirts Complete the Profile
Side skirts are sometimes overlooked when planning an exterior build, but they play an important role in connecting the front and rear of the car visually.
A more aggressive front bumper paired with completely stock side skirts can leave the vehicle looking unfinished.
Duraflex offers standalone side skirts as well as components included in complete multi-piece kits.
For example, its BMW 6 Series 1M Look package combines the front bumper with M Sport-inspired side skirts and a rear bumper to create a more cohesive transformation.
This illustrates why complete kits can be useful when the goal is a consistent design rather than a single exterior modification.
Hoods, Vents, and Functional Styling
Duraflex's catalog also extends into more specialized exterior components.
Hoods can introduce different contours and vent designs, while universal air vents can be incorporated into custom hood or fender projects.
The Duraflex Sonic heat-extractor vent ducts available through XPH, for example, are designed for custom installation into hoods, fenders, or other body panels. They use hand-laid fiberglass construction and a flexible polymer blend, with the final installation requiring appropriate modification and preparation.
These types of components are particularly relevant to custom builds where the owner is not simply replacing one factory panel with another.
They become part of the fabrication process.
Aerodynamics and Appearance Can Work Together
Duraflex components are primarily exterior modifications, but many designs incorporate changes to the vehicle's airflow and aerodynamic profile.
Front lips, bumpers, diffusers, spoilers, wings, vents, and fender designs can all influence the way air moves around the vehicle.
However, aerodynamic claims should always be considered in the context of the specific product.
A styling component should not automatically be assumed to provide measurable downforce or track-level aerodynamic performance.
For many builds, the main objective is a combination of visual presence, airflow management, and a more purposeful exterior design.
Duraflex for Different Types of Builds
The broad Duraflex catalog makes the brand relevant to several different types of projects.
Street Builds
A front lip, side skirts, spoiler, or replacement bumper can give a daily-driven vehicle a more aggressive appearance without requiring a complete conversion.
Widebody Builds
Fender flares and wider body components can form the foundation for a broader stance and more substantial wheel-and-tire package.
Show Cars
Complete body kits and highly customized exterior components provide a foundation for builds where the bodywork is a major part of the finished vehicle.
Performance-Inspired Builds
Aggressive bumpers, ducts, vents, spoilers, and aerodynamic components can complement vehicles already equipped with upgraded suspension, wheels, brakes, or powertrain components.
Custom Projects
Universal components and individual panels allow fabricators to create something substantially different from the original vehicle.
Plan the Installation Before Ordering
Because Duraflex components can require preparation and modification, fitment should be checked carefully before beginning an installation.
Verify:
- exact vehicle year and chassis
- body style
- trim or package requirements
- included components
- whether additional hardware is required
- compatibility with existing exterior modifications
- required bodywork and paint preparation
Some products have very specific fitment requirements.
The BMW F22/F23 MHR fender flares, for example, are specifically listed for M Sport models, while individual Duraflex kits can have their own model, year, and trim requirements.
Getting the fitment right before fabrication begins can save significant time and expense.
Build the Exterior You Actually Want
Duraflex is ultimately about customization.
The catalog provides the components; the final result depends on how they are selected, fitted, prepared, painted, and combined with the rest of the vehicle.
That makes Duraflex particularly useful for enthusiasts who want to move beyond simple bolt-on styling and create an exterior with a genuinely different identity.
Whether the goal is a subtle OEM-inspired upgrade, a widebody transformation, a show build, or a completely custom project, the starting point is choosing components that work together.
