The Bentley Continental GT is a grand tourer that delivers a blend of luxury and high-performance driving. Its suspension system is critical to that experience, providing a smooth ride while maintaining composure at speed. Over time, suspension components wear out or may need upgrading for better handling. This guide covers the key suspension parts for the Bentley Continental GT, what they do, and how to choose the right replacements.

Overview of the Bentley Continental GT Suspension System
The Continental GT uses a sophisticated air suspension system combined with adaptive dampers. Early models (2004–2011) have a conventional coil spring setup on some variants, but most feature air springs. The system includes struts, air lines, compressors, and control modules. Later generations (2012–present) use a multi-link front and rear design with air springs and continuously variable damping.
Key Components at a Glance
- Air Springs (Struts): Replace the coil springs, allowing ride height adjustment and comfort.
- Shock Absorbers (Dampers): Control oscillation; often integrated into the strut assembly.
- Control Arms: Connect the wheel hub to the chassis; wear out over time.
- Sway Bars (Anti-roll Bars): Reduce body roll during cornering.
- Bushings: Rubber or polyurethane components that isolate vibration and allow movement.
- Compressor and Valve Block: Maintain air pressure in the air springs.
- Ride Height Sensors: Monitor suspension position for leveling.
Common Suspension Issues in the Bentley Continental GT
Owners often report air spring leaks, failing compressors, and worn control arm bushings. The air suspension system is sensitive to cold weather and age. Indicators of trouble include a sagging corner, bumpy ride, or error messages on the dashboard. Regular inspection helps catch problems early.
Types of Suspension Parts: OEM vs Aftermarket
OEM Parts
Original Equipment Manufacturer parts are identical to those installed at the factory. They guarantee fit and function, and are often covered by a warranty. For Bentley, OEM parts come from suppliers like Continental or ZF. They are reliable but can be expensive.
Aftermarket Options
Aftermarket parts offer a range of prices and quality levels. Some are direct replacements that meet or exceed OEM specs. Others are performance upgrades, such as stiffer bushings or adjustable dampers. Reputable brands include Arnott (for air struts), Bilstein (shocks), and Lemförder (control arms). Aftermarket parts can save money but require careful selection to avoid poor fitment or reduced ride quality.
Remanufactured Parts
Remanufactured air struts and compressors are a middle ground. They are rebuilt to OEM standards and often include new seals and valves. They cost less than new OEM parts and can be a good choice for budget-conscious owners.
Key Suspension Parts Explained
Air Springs (Struts)
The air spring supports the vehicle weight and adjusts ride height. On the Continental GT, the front and rear struts are different. Failure often occurs due to a cracked rubber bellows or a clogged air line. When replacing, consider the brand: Arnott offers a popular replacement with a lifetime warranty. OEM replacements are available from Bentley dealerships.
Shock Absorbers (Dampers)
Many Continental GTs have electronically controlled dampers that adjust based on driving mode. Replacing these requires a compatible part. Aftermarket options like Bilstein B6 or B8 can be used, but the electronic control may need to be adapted. For a direct replacement, stick with OEM or Dampers from the original supplier (Sachs or ZF).
Control Arms and Bushings
The control arms in the front and rear have ball joints and bushings that wear, causing clunking noises and poor alignment. The lower control arms are common failure points. Aftermarket control arms from Lemförder are OE-quality. Polyurethane bushings can be used for a firmer feel but may increase road noise.
Stabilizer (Sway) Bars and Links
Upgrading sway bars can reduce body roll for more aggressive driving. However, it may compromise ride comfort. Most owners replace worn stabilizer links with OEM or aftermarket units. They are inexpensive and easy to install.
Air Suspension Compressor
The compressor pumps air into the springs. It can fail due to moisture or overwork. Rebuild kits are available, but many owners choose a new or remanufactured unit. Make sure the new compressor matches your model year.
Choosing the Right Suspension Parts
Consider Your Driving Needs
- Daily driving: Stick with OEM or high-quality aftermarket replacements for comfort and longevity.
- Performance driving: Upgrade to stiffer dampers, sway bars, and polyurethane bushings. Keep in mind that this may increase harshness.
- Off-roading (rare): The Continental GT is not designed for off-road, but if you need more ground clearance, adjustable air suspension can help.
Budget and Quality
OEM parts are most expensive but offer peace of mind. Aftermarket parts like Arnott air struts provide a good balance of price and reliability. Avoid cheap no-name parts, as they may fail quickly. Check reviews from Bentley forums and trusted mechanics.
Compatibility
Always verify that the part fits your specific year and model. Bentley made changes between 2004–2006, 2007–2011, and 2012+ (C6, C7 generations). The suspension system differs between V8 and W12 engines as well. Use your VIN to confirm fitment.
Installation Tips
Replacing suspension parts on a Bentley Continental GT often requires specialized tools and knowledge. Air suspension systems must be depressurized before opening. Spring compressors are needed for coil spring setups. After installation, an alignment is necessary. If you are not experienced, hire a mechanic familiar with European luxury cars.
Recommended Brands
- Air Springs: Arnott (aftermarket), Bentley OEM (continental OEM supplier)
- Shocks/Dampers: Bilstein, Sachs, ZF
- Control Arms: Lemförder, TRW
- Bushings: Powerflex (polyurethane), OEM rubber
- Compressors: Arnott, Hitachi (OEM supplier)
Practical Final Recommendation
For most Bentley Continental GT owners, the best approach is to use a mix of OEM and high-quality aftermarket parts. Replace air springs with Arnott for a cost-effective solution that includes a lifetime warranty. Use OEM dampers if you have the electronic damping system, or opt for Bilstein B6 if you want a slightly firmer ride. For control arms, choose Lemförder for reliable fitment. Sway bar links and bushings can be aftermarket from reputable brands. Always replace worn parts in pairs (both front or both rear) to maintain balance. Invest in a professional alignment after any suspension work. By following this guide, you can keep your Continental GT riding smoothly for years to come.
