2024 Mercedes-Benz C-Class K-Frame

Product Details

The 2024 Mercedes-Benz C-Class K-Frame is a front structural suspension carrier used on compatible Mercedes-Benz C-Class W206 vehicles. Often referred to in the automotive parts trade as a K-frame, front subframe, engine cradle, integral carrier, or front axle carrier, this component forms an important mounting structure beneath the front of the vehicle.

Mercedes-Benz officially refers to the component as an Integral Carrier / Front Axle Carrier. For a 2024 Mercedes-Benz C300 4MATIC, the official Mercedes-Benz parts catalog lists genuine reference 223-620-92-04 as the front axle carrier.

The 2024 Mercedes-Benz C-Class K-Frame is suitable for collision repair centers, Mercedes-Benz specialists, suspension workshops, vehicle rebuilders, automotive parts distributors, salvage businesses, exporters, and wholesale buyers sourcing W206 chassis and suspension components.

Because Mercedes-Benz C-Class models differ by drivetrain, AMG specification, suspension system, and production configuration, buyers should confirm compatibility using the VIN and original component number before ordering.

What Is a Mercedes-Benz K-Frame?

“K-frame” is a common automotive trade term rather than the primary terminology used in the Mercedes-Benz electronic parts catalog.

For the W206 C-Class, Mercedes-Benz describes the main structural component as an:

Integral Carrier

or

Front Axle Carrier

The 2024 Mercedes-Benz C-Class K-Frame provides mounting points for several front suspension and chassis components and attaches directly to the vehicle body structure.

Mercedes-Benz’s catalog shows dedicated mounting bolts securing the integral carrier to the body and identifies separate suspension components that connect to the carrier.

OEM Reference 223-620-92-04

A major OEM reference associated with compatible W206 applications is:

Mercedes-Benz Part Number: 223-620-92-04
Alternative format: A2236209204
Description: Integral Carrier
Application description: Front axle carrier

Mercedes-Benz USA identifies 223-620-92-04 as a genuine Integral Carrier and specifically describes it as a Front axle carrier.

The official 2024 C300 4MATIC catalog also lists this part directly within the Wheel Well, Front Axle Carrier section.

This number should be treated as an important compatibility reference rather than automatically assumed to fit every 2024 C-Class configuration.

Mercedes-Benz W206 Compatibility

The 2024 Mercedes-Benz C-Class K-Frame belongs to the W206 C-Class platform.

Potential applications can include compatible versions of:

• 2024 Mercedes-Benz C300
• 2024 Mercedes-Benz C300 4MATIC
• 2024 Mercedes-AMG C43
• Selected Mercedes-AMG C63 S E Performance configurations

Mercedes-Benz documentation confirms that the W206 platform uses an integral front axle carrier and that the 223-620-92-04 carrier appears in multiple modern Mercedes applications. The same front axle carrier reference is also documented in the C43 AMG parts catalog.

However, VIN verification is required before claiming exact interchangeability.

C300 4MATIC Fitment

For the 2024 Mercedes-Benz C300 4MATIC 2.0L mild-hybrid application, Mercedes-Benz specifically lists:

223-620-92-04 – Integral Carrier / Front Axle Carrier

within the front axle carrier assembly.

This provides a strong OEM reference when sourcing a 2024 Mercedes-Benz C-Class K-Frame for a C300 4MATIC.

Customers should still provide the VIN because production revisions and regional specifications can affect final parts identification.

AMG C43 and C63 Fitment

AMG vehicles require additional care when checking K-frame compatibility.

Mercedes-Benz parts data for the C43 AMG also lists 223-620-92-04 as the integral front axle carrier on compatible W206 applications.

Mercedes-Benz also uses the same reference within later C63 S E Performance front axle carrier catalogs, demonstrating shared architecture across several 206-series performance applications.

However, buyers should not assume that every component attached to an AMG K-frame is identical to a C300 assembly.

Control arms, steering, driveline components, suspension hardware, cooling equipment, and other attached parts may vary.

K-Frame vs Complete Front Suspension Assembly

The 2024 Mercedes-Benz C-Class K-Frame should not automatically be interpreted as a complete front suspension assembly.

A bare front axle carrier normally refers primarily to the structural carrier itself.

Depending on the specific used or supplied assembly, additional attached parts may include:

• Lower control arms
• Tension struts
• Steering rack
• Anti-roll bar
• Suspension links
• Mounting brackets
• Engine or transmission-related brackets
• Hardware
• Front differential-related components on applicable 4MATIC vehicles

Mercedes-Benz catalogs list many of these components separately from the integral carrier. For example, spring links and tension struts are individual service components attached to the carrier.

The exact package contents should therefore be clearly confirmed before purchase.

Steering Rack Not Automatically Included

A complete-looking used K-frame may sometimes be supplied with a steering rack still installed.

However, the steering rack should not be assumed included with the 2024 Mercedes-Benz C-Class K-Frame unless it is specifically shown and identified in the quotation.

Steering equipment can also vary according to vehicle specification and electronic configuration.

If the steering rack is included, buyers should request:

• OEM steering rack number
• Connector photographs
• Condition information
• Donor VIN where available

Control Arms and Suspension Links

The front axle carrier provides attachment points for several suspension links.

Mercedes-Benz parts documentation for the W206 identifies components including:

• Spring links
• Tension struts
• Bushings
• Steering knuckles
• Fastening hardware

as separate components within the front axle system.

If purchasing a used 2024 Mercedes-Benz C-Class K-Frame, buyers should therefore confirm whether these suspension components remain attached or whether the product is supplied as a bare carrier.

4MATIC Drivetrain Considerations

The 4MATIC system adds front drivetrain components that must be considered during replacement.

The 2024 Mercedes-Benz C-Class K-Frame for a 4MATIC vehicle operates in an area containing front axle drive and axle shaft components.

Mercedes-Benz’s 2024 C300 4MATIC catalog separately identifies front axle drive and front axle shaft systems alongside the front axle carrier.

For this reason, RWD and 4MATIC vehicle information should always be provided during fitment verification.

Do not assume compatibility based only on the model year.

Replacement After Collision Damage

A K-frame can require replacement after severe front-end or underbody impact.

Possible reasons include:

• Collision damage
• Bent mounting points
• Structural deformation
• Suspension impact
• Road-debris impact
• Damaged control-arm mounting locations
• Vehicle rebuilding

If the 2024 Mercedes-Benz C-Class K-Frame is being replaced following an accident, technicians should also inspect surrounding structural and suspension components.

A bent control arm or wheel can indicate forces that may have affected the carrier.

Used K-Frame Inspection

When purchasing a used front axle carrier, inspect:

• Main structural frame
• Suspension mounting points
• Steering rack mounting points
• Welded areas
• Bolt holes
• Bushings where present
• Impact marks
• Cracks
• Distortion
• Corrosion
• Previous repairs

A 2024 Mercedes-Benz C-Class K-Frame should not be described as straight or undamaged unless its physical condition has been properly inspected.

Clear photographs of the upper and lower surfaces are recommended for remote and wholesale buyers.

Mounting Hardware

Mercedes-Benz lists dedicated fasteners for mounting the integral carrier to the body.

For the W206 front axle carrier, the catalog includes front and rear carrier mounting bolts as separate parts.

Mounting bolts and nuts should therefore not automatically be assumed to come with the replacement carrier.

Where Mercedes-Benz repair procedures specify replacement fasteners, technicians should follow the appropriate service instructions.

Professional Installation Required

Professional installation of the 2024 Mercedes-Benz C-Class K-Frame is strongly recommended.

Replacing a front axle carrier involves major suspension and chassis work.

Installation can require removal or support of:

• Suspension components
• Steering components
• Drivetrain components
• Underbody panels
• Brackets
• Wiring or lines near the carrier

After installation, wheel alignment and suspension geometry should be checked.

Vehicles equipped with advanced steering or driver-assistance systems may also require appropriate calibration following major chassis or steering work.
