Chrysler 300 Wide Body Kit: Styles, Fitment, Materials, and Buying Guide
Quick Answer: A Chrysler 300 wide body kit adds wider fenders, flares, side skirts, bumper extensions, or other exterior components to create a broader and more aggressive appearance. Before buying one, check your Chrysler 300’s model year, kit fitment, material, wheel and tire specifications, installation requirements, and total project cost.
A Chrysler 300 wide body kit adds width and a more aggressive appearance to the Chrysler 300 by extending areas such as the fenders, bumpers, and side skirts. Depending on the design, a wide-body conversion can also create additional space for wider wheels and tires.
The Chrysler 300 has a naturally broad, muscular sedan shape, making it a strong platform for dramatic exterior customization. However, a wide-body kit is a larger project than installing a simple lip or spoiler, so fitment, installation, wheel clearance, and total cost need to be considered carefully.
What Is a Chrysler 300 Wide Body Kit?
A Chrysler 300 wide body kit is a collection of aftermarket exterior components designed to make the vehicle appear wider.
Unlike a conventional body kit that may simply replace factory styling components, a wide-body setup generally extends the vehicle’s body around the wheel arches.
Depending on the manufacturer, a kit may include:
- Front wide fenders
- Rear wide fenders
- Front bumper extensions
- Rear bumper extensions
- Side skirts
- Fender flares
- Front lips
- Rear diffusers
- Spoilers
- Mounting hardware
Some products are sold as complete kits, while others are available as individual components.
Why Install a Wide Body Kit on a Chrysler 300?
The main reason is exterior customization. A wide-body design can give the Chrysler 300 a lower, broader, and more aggressive visual presence.
Other reasons include:
More Aggressive Styling
The factory Chrysler 300 already has a substantial road presence. Extended fenders and side skirts can emphasize that width.
Wider Wheel and Tire Setup
Depending on the design, additional body width can provide room for wider wheels and tires.
However, a wide-body kit itself does not automatically create additional wheel clearance. Wheel offset, suspension geometry, tire dimensions, and the specific body design all need to be considered together.
Custom Show Builds
Wide-body conversions are often used for customized street and show cars where exterior appearance is a major part of the build.
Individual Styling
Aftermarket parts allow owners to create a look that differs significantly from the factory configuration.
Chrysler 300 Generations and Fitment
Fitment is particularly important when searching for a Chrysler 300 wide body kit because Chrysler 300 models have changed across different production periods.
| Generation | Approximate Production Period | Key Consideration |
|---|---|---|
| First generation | 2005–2010 | Different body design from later models |
| Second generation | 2011–2023 | Different exterior and component fitment |
A kit designed for a 2005 Chrysler 300 should not be assumed to fit a 2015 or 2020 model.
Even within the same generation, bumper designs, trim levels, facelifts, and existing modifications can affect compatibility.
Always verify the exact model year and application before purchasing.
Popular Chrysler 300 Wide Body Styles
A wide-body build does not have to follow one specific design language.
OEM-Inspired Wide Body
An OEM-inspired setup retains some of the factory Chrysler 300’s visual character while adding wider fenders and subtle aero components.
This can be a good approach when you want the vehicle to look customized without completely changing its original design.
Aggressive Wide Body
An aggressive kit may use:
- Pronounced fender extensions
- Deep front splitters
- Extended side skirts
- Large rear diffusers
- Larger rear spoilers
This creates a significantly more noticeable appearance.
Performance-Inspired Styling
A performance-oriented design may combine wider fenders with a lower stance, larger wheels, and aerodynamic components.
The body kit is only one part of this type of build. Wheel and tire selection, suspension, braking components, and overall vehicle setup should be considered together.
Show-Car Styling
A show-focused Chrysler 300 can use more dramatic bodywork, custom paint, oversized wheels, and additional exterior details.
Because practicality may be less important for a dedicated show vehicle, the owner has more freedom with the design.
Expert Tip: Do not order a wide-body kit before deciding on your wheel and tire specifications. The final fender width, wheel offset, tire width, and suspension height need to work together. Planning these measurements beforehand can prevent expensive clearance and fitment problems after installation.

Materials Used in Wide Body Kits
Material choice affects flexibility, weight, finishing, durability, and price.
Fiberglass
Fiberglass is widely used for aftermarket body panels.
It allows manufacturers to create complex shapes and is often less expensive than premium materials.
Advantages:
- Lightweight
- Relatively affordable
- Easy to shape
- Suitable for custom designs
Considerations:
- Can crack under impact
- Less flexible than many plastics
- May require additional preparation
- Fitment can vary
ABS Plastic
ABS plastic offers a balance between flexibility and durability.
It is commonly used for various automotive exterior components and can be suitable for owners who want a more flexible material than fiberglass.
Polyurethane
Polyurethane is more flexible than many rigid body-panel materials.
It can be useful for certain lower exterior components that may experience minor contact.
Carbon Fiber
Carbon fiber provides a premium appearance and high strength-to-weight characteristics.
It is generally more expensive than fiberglass or conventional plastic.
| Material | Flexibility | Weight | Cost Level |
|---|---|---|---|
| Fiberglass | Low to moderate | Light | Lower |
| ABS | Moderate | Moderate | Moderate |
| Polyurethane | High | Moderate | Moderate |
| Carbon fiber | Low | Very light | Higher |
How to Choose a Chrysler 300 Wide Body Kit
1. Confirm Your Model Year
Start with the exact year of your Chrysler 300.
Check whether the kit was designed for the same generation and body configuration.
2. Check the Kit Contents
Determine whether the package includes:
- Front fenders
- Rear fenders
- Side skirts
- Bumper extensions
- Fender flares
- Mounting hardware
Do not assume every component shown in photographs is included.
3. Measure Your Wheel Setup
Wheel specifications become particularly important with a wide-body conversion.
Check:
- Wheel diameter
- Wheel width
- Offset
- Tire width
- Tire sidewall
- Suspension height
A wider body does not automatically mean any wheel or tire combination will fit.
4. Consider Your Suspension
If you plan to lower the Chrysler 300, decide on suspension height before finalizing the bodywork.
A very low setup combined with wide tires and aggressive fenders can create rubbing or clearance issues.
5. Think About Daily Driving
A wide-body Chrysler 300 can remain practical, but the finished setup should match the roads you regularly use.
Consider:
- Speed bumps
- Parking garages
- Narrow parking spaces
- Steep driveways
- Uneven roads
Wide Body Kit vs Standard Body Kit
| Feature | Wide Body Kit | Standard Body Kit |
|---|---|---|
| Main purpose | Increase visual width | Change exterior styling |
| Fender modification | Common | Usually limited |
| Wheel clearance | May increase depending on design | Usually unchanged |
| Installation complexity | Higher | Moderate |
| Bodywork | Often required | Depends on component |
| Styling impact | Significant | Ranges from subtle to aggressive |
| Cost | Often higher | Varies |
A standard body kit may be enough if your primary goal is appearance. A wide-body setup makes more sense when you specifically want a wider visual profile or are planning a broader wheel-and-tire build.
Installation of a Chrysler 300 Wide Body Kit
Wide-body installation is usually more involved than installing individual exterior accessories.
A typical process may include:
- Removing factory exterior components
- Test-fitting the wide-body parts
- Marking cutting or mounting areas where required
- Modifying the original panels if specified
- Securing the new components
- Checking wheel and tire clearance
- Preparing surfaces
- Applying primer and paint
- Reassembling the exterior
- Checking final alignment and clearance
The exact process depends on the kit.
For kits requiring permanent cutting or significant body modification, professional installation is generally appropriate.
How Much Does a Chrysler 300 Wide Body Kit Cost?
There is no single price for a Chrysler 300 wide-body conversion.
The final cost depends on the manufacturer, materials, number of components, design, availability, and installation requirements.
You should account for more than the kit itself.
Additional costs can include:
- Shipping
- Paint
- Body preparation
- Cutting or modification
- Installation
- Mounting hardware
- Wheels
- Tires
- Suspension components
- Alignment
If you are building the car from scratch, calculate the total project cost before ordering the first component.
Common Mistakes to Avoid
Buying the Wrong Generation
A wide-body kit designed for one Chrysler 300 generation may not fit another.
Choosing Wheels After Installing the Kit
Wheel and tire specifications should be part of the planning process from the beginning.
Ignoring Panel Preparation
Fiberglass and other aftermarket panels may require fitting and surface preparation before painting.
Assuming Wide Body Means Better Performance
A wider exterior does not automatically improve handling or aerodynamic performance.
The actual result depends on the complete vehicle setup.
Forgetting Road Clearance
Extended front lips and side skirts can create clearance problems on ordinary roads.
