2010 Range Rover Front Air Suspension Part Number Guide

If you own a 2010 Range Rover (L322 generation), you know the front air suspension can wear out over time. Identifying the correct front air suspension part number is critical for a successful repair. This guide covers the main components, OEM numbers, common aftermarket equivalents, and tips to ensure you get the right parts.

Understanding Your Range Rover's Front Air Suspension System

The 2010 Range Rover uses a self-leveling air suspension system on both front wheels. Each front corner consists of an air spring (air bag) integrated with a shock absorber – often called a front air strut or front shock absorber with air spring. The system also includes the air suspension compressor, valve block, and height sensors. When diagnosing a problem, you must identify whether the leak or failure is in the strut, the air line, or the compressor.

Common symptoms of front air suspension failure include:

• The front end sagging after sitting for a while
• The compressor running excessively or not at all
• Suspension fault warnings on the dashboard
• Uneven ride height or a knocking noise from the front

Main Front Air Suspension Components and Their Part Numbers

Front Air Strut (Complete Assembly)

The front air strut is the most common replacement part. It includes the air spring, shock absorber, and sometimes the electronic height sensor. For the 2010 Range Rover L322, there are two main OEM suppliers: Bilstein and Continental (formerly Phoenix). OEM part numbers may vary by VIN range or optional equipment (e.g., Adaptive Dynamics vs. standard).

OEM Part Numbers:

• Left Front (Driver Side): LR041801 (air spring + damper) or LR020632 (air spring only)
• Right Front (Passenger Side): LR041802 (air spring + damper) or LR020633 (air spring only)

Note: The complete strut assemblies (LR041801/LR041802) include the air spring and shock as one unit. If your vehicle has Adaptive Dynamics (active roll stabilization), the part numbers differ.

Adaptive Dynamics (Active Roll Control):

• Left Front: LR031726
• Right Front: LR031727

Aftermarket Options: Brands like Arnott, Dorman, and A-Premium offer complete struts that match OEM fit and function. For example:

• Arnott AS-3617 (left) and AS-3618 (right) – include new air springs and shocks, sometimes with a lifetime warranty.
• Dorman 949-050 (left) and 949-051 (right) – budget-friendly but reliable.

When using aftermarket parts, always verify that the part number matches your VIN and suspension type (standard or Adaptive Dynamics).

Front Air Spring (If replacing separately)

Some owners choose to replace only the air spring bladder if the shock absorber is still good. However, on the L322, the air spring and shock are often unitized, so separate air springs are less common.

• OEM Air Spring (without shock): Left LR020632, Right LR020633
• Aftermarket: Arnott AB-3619 (fits both sides? Actually Arnott sells the bladder as part of the strut assembly, not separately. Check with supplier.)

Air Suspension Compressor

If the compressor fails, the entire system cannot maintain pressure. The 2010 Range Rover uses a Hitachi compressor assembly mounted in the engine bay (driver side) or under the vehicle, depending on model.

• OEM Compressor: LR045251 or LR015303 (updated version)
• Aftermarket: Arnott P-2285 or other brands; note that some cheap compressors may overheat quickly.

Valve Block and Air Lines

Leaks often occur at the valve block or connections. The valve block controls air distribution to each corner.

• OEM Valve Block: LR015302
• Air Line Repair Kit: LR024886 (includes connectors and tubing)

How to Find the Exact Part Number for Your Vehicle

The safest way to confirm the correct part number is to:

1. Check your vehicle identification number (VIN). You can find it on the driver’s side windshield or door jamb.
2. Look up the parts catalog for the 2010 Range Rover L322 using your VIN. Many auto parts websites offer VIN-specific lookups.
3. Examine the old part for any labels or stamped numbers. OEM parts usually have a Land Rover logo and a part number.
4. Note whether your vehicle has Adaptive Dynamics (look for a sticker on the front strut or check with a dealer).

If you’re not sure, call a Land Rover dealer parts department with your VIN – they can give you the exact OEM number. Then you can compare aftermarket options.

Aftermarket vs. OEM: Considerations

OEM parts are made to Land Rover’s specifications and generally offer the best fit and longevity. However, they are often more expensive. Aftermarket parts from reputable brands (Arnott, Dorman, Bilstein) are widely used and can save money. Arnott, for example, specializes in air suspension and often provides lifetime warranties.

Potential pitfalls:

• Some aftermarket struts may have a different ride quality than OEM.
• Cheap no-name struts may fail quickly, leading to repeated labor costs.
• Always replace struts in pairs (both front) to maintain even handling.

Installation Tips and Common Mistakes

Replacing front air suspension parts is a job for experienced DIYers or professionals. A few key points:

• Always depressurize the air suspension system before disconnecting any lines. You can do this by removing the compressor relay and opening a schrader valve on the dryer (or by using a scan tool).
• Use new O-rings and seals whenever disconnecting air lines.
• After installation, you may need to recalibrate the ride height using a diagnostic tool (e.g., IIDTool, Autel, or dealer software) to avoid suspension errors.
• If the compressor runs excessively after repair, check for leaks with soapy water.

Final Recommendation

For most 2010 Range Rover owners needing front air suspension parts, the best approach is to:

• Identify whether you have standard or Adaptive Dynamics suspension.
• Use your VIN to confirm the OEM part number.
• Consider a complete front air strut assembly from a trusted aftermarket brand like Arnott or Bilstein. They are often more affordable than OEM but still reliable.
• Replace both front struts at the same time to maintain balance.
• If the compressor is also failing, replace it with an updated OEM or high-quality aftermarket unit (avoid cheap compressors).

By matching the correct part number and choosing quality components, you can restore your 2010 Range Rover’s ride height and comfort without overspending. Always verify compatibility before purchase – you don’t want to end up with a part that doesn’t fit.
