New BILSTEIN B4, B6 & Air Suspension Options for the Mercedes-Benz GLC

BILSTEIN has expanded its aftermarket suspension range for the latest-generation Mercedes-Benz GLC, introducing new shock absorber and air suspension options for the X254 GLC SUV and C254 GLC Coupé.

The expanded range gives Mercedes-Benz GLC owners access to both OE-quality replacement components and performance-focused suspension upgrades, including BILSTEIN B4 shock absorbers, BILSTEIN B6 performance shock absorbers and BILSTEIN B4 air spring modules.

Whether you're replacing worn factory suspension or looking to improve the way your GLC drives, here's what you need to know about the latest additions.

New BILSTEIN Suspension for the Mercedes-Benz GLC X254

Introduced as the successor to the X253, the Mercedes-Benz GLC X254 combines the comfort and practicality expected from a premium SUV with increasingly sophisticated suspension technology.

As more X254 models begin to accumulate mileage, demand for high-quality aftermarket suspension components is naturally increasing.

BILSTEIN has responded by introducing both B4 OE replacement shock absorbers and B6 high-performance shock absorbers for the Mercedes-Benz GLC X254. The B4 replacement shock absorber range has also been expanded to cover the GLC Coupé C254.

This means GLC owners can choose between restoring their vehicle's original suspension characteristics or upgrading to a more performance-focused damper.

BILSTEIN B4 – The OE Replacement Choice

For drivers looking to restore their GLC's suspension to its original characteristics, BILSTEIN B4 is the natural choice.

BILSTEIN specifically engineers its B4 shock absorbers as OE replacements for the vehicle's standard equipment. The new GLC applications therefore provide vehicle-specific fitment while retaining the familiar handling characteristics expected from the original suspension.

Why choose BILSTEIN B4?

• OE replacement solution
• Vehicle-specific fitment
• Designed to retain original handling characteristics
• Reliable everyday performance
• Ideal for replacing worn or ageing factory dampers

For owners happy with the comfort and handling of their standard Mercedes-Benz GLC, B4 provides a straightforward replacement option without turning the car into something it was never intended to be.

BILSTEIN B6 – More Performance Without Lowering

Want something a little more performance focused?

That's where the BILSTEIN B6 comes in.

BILSTEIN B6 is designed as an upgraded replacement for the original shock absorbers, providing greater driving stability, increased performance reserves and more precise handling. Crucially, it achieves this without requiring the vehicle to be lowered.

That makes B6 particularly interesting for GLC owners who want to improve the way their vehicle responds without committing to a lowered suspension setup.

Why choose BILSTEIN B6?

• Performance-focused replacement damper
• Greater driving stability
• More precise handling
• Increased performance reserves
• Retains the vehicle's standard ride height
• No lowering springs required

For a large premium SUV such as the GLC, the additional control offered by an uprated damper can be particularly useful when you're looking for a more confidence-inspiring and responsive driving experience.

BILSTEIN B4 vs B6 – What's the Difference?

The choice ultimately comes down to what you want from your Mercedes-Benz GLC.

Choose BILSTEIN B4 if you want to replace worn original shock absorbers and maintain the vehicle's familiar factory-style ride and handling.

Choose BILSTEIN B6 if you'd like to take the opportunity to improve the suspension with greater stability and more precise handling while keeping the standard ride height.

Put simply:

B4 = OE-quality replacement

B6 = Performance upgrade without lowering

This makes the B6 an appealing option for drivers who don't necessarily want a full sports suspension or lowered setup but would still like to sharpen up the way their GLC drives.

New BILSTEIN B4 Air Spring Modules

It's not just conventional shock absorbers that are being added to the range.

BILSTEIN is also expanding its aftermarket offering with B4 air spring modules for the Mercedes-Benz GLC X254 and GLC Coupé C254.

BILSTEIN states that versions for both the front and rear axles are set to follow, further increasing the replacement options available for GLC models equipped with air suspension.

Air suspension can provide an excellent combination of ride comfort, control and versatility, but as vehicles age and mileage increases, individual suspension components can eventually require replacement.

Having a BILSTEIN aftermarket option gives GLC owners another high-quality route when that time comes.

BILSTEIN's OE Air Suspension Experience

One of the particularly important points behind the new range is BILSTEIN's existing experience with Mercedes-Benz GLC suspension.

BILSTEIN is an OE supplier of electronic dampers used with the air suspension systems in the X254 and C254 in series production. This means the company can bring experience gained from original-equipment production into its aftermarket suspension range.

For owners looking to replace sophisticated suspension components on a modern premium vehicle, that OE background is an important consideration.

Mercedes-Benz GLC X254 & C254 Suspension Options

With the latest expansion, BILSTEIN is building a comprehensive suspension offering for the current-generation Mercedes-Benz GLC.

Depending on the specific vehicle and suspension configuration, the new range includes:

• BILSTEIN B4 – OE replacement shock absorbers
• BILSTEIN B6 – High-performance shock absorbers
• BILSTEIN B4 Air Spring Modules – Replacement components for GLC models equipped with air suspension

It's important to check the exact application against your vehicle before ordering, particularly given the different suspension configurations available across the GLC range.

When Should You Replace Your GLC Shock Absorbers?

Shock absorbers naturally wear over time, and deterioration isn't always immediately obvious because it can happen gradually.

As mileage increases, you may begin to notice changes such as increased body movement, reduced stability, poorer control over bumps or a generally less precise feeling from the suspension.

Shock absorbers also play an important role beyond ride comfort. They help keep the tyres controlled and in contact with the road, making correctly functioning suspension important to the vehicle's overall handling and stability.

If your GLC's dampers need replacing, it can also be the ideal opportunity to decide whether you want to restore the original setup with BILSTEIN B4 or upgrade to BILSTEIN B6.
