Damper & Suspension Services

Full Damper Refurbishment

Inspect the damper and confirm whether refurbishment is suitable. The work required depends on its part number, internal condition and any damage.

Spring Replacement

Inspect springs for corrosion, damage and correct fitment. Replacement options are checked against the car’s suspension specification.

Accumulator Service

On cars with the relevant hydraulic system, investigate pressure and accumulator condition as part of suspension diagnosis.

Seal & Valve Rebuild

Inspect seals and internal components to establish the source of leakage or damping faults. The repair scope is agreed after assessment.

Nose Lift Damper Service

Investigate lift operation, leaks and warning messages on cars with the front lift system fitted.

Suspension Diagnostics

Check warning messages, mechanical condition and the system fitted to the vehicle. Ride quality symptoms can have more than one cause.

Damper Refurbishment & Exchange Options

Check Availability First

A rebuilt exchange damper may be an option for some cars. Availability depends on the model, part number and condition of the unit being returned.

We confirm parts, refurbishment or exchange arrangements, and expected lead time before scheduling installation. The car may need to remain off the road while work is completed.

Road test and final quality verification before handback

Warning Signs Your Dampers Need Attention

Suspension Failure Warning

Record the exact warning and any change in ride or handling. A scan and inspection are needed to identify the cause.

Harsh Or Crashy Ride

Tyres, dampers, joints and hydraulic components where fitted can affect ride quality. Inspection should consider the full suspension system.

Vehicle Sagging Or Leaning

Uneven stance needs a mechanical inspection. Check springs, tyres and the relevant suspension components rather than assuming an accumulator fault.

Visible Spring Corrosion

Surface corrosion and deeper damage need to be distinguished. Have a damaged or suspect spring inspected before continued use.

Uneven Tyre Wear

Tyre pressure, alignment and worn components can all contribute. Inspect the tyres and suspension before choosing a repair.

McLaren Models We Service

MP4-12C

We assess MP4-12C damper leaks, ride concerns and suspension warnings. The parts and repair plan depend on the system fitted and inspection findings.

650S

We assess 650S damper leaks, ride concerns and suspension warnings. The parts and repair plan depend on the system fitted and inspection findings.

675LT

We assess 675LT damper leaks, ride concerns and suspension warnings. The parts and repair plan depend on the system fitted and inspection findings.

570S / 570GT

These Sports Series cars use adaptive dampers and anti-roll bars. Inspection and refurbishment options must match their suspension layout.

720S / 750S

We assess 720S / 750S damper leaks, ride concerns and suspension warnings. The parts and repair plan depend on the system fitted and inspection findings.

765LT

We assess 765LT damper leaks, ride concerns and suspension warnings. The parts and repair plan depend on the system fitted and inspection findings.

Senna

Contact us with the VIN, service history and proposed work. Model-specific requirements and specialist support are confirmed before booking.

GT / Artura

GT and Artura have different drivetrains and service requirements. Send the VIN and symptoms so we can confirm the appropriate inspection and repair scope.

600LT

These Sports Series cars use adaptive dampers and anti-roll bars. Inspection and refurbishment options must match their suspension layout.

Different Models, Different Suspension Systems

Identify The System Fitted

Several Super Series models use interconnected hydraulic suspension. Sports Series cars such as the 570S use adaptive dampers and anti-roll bars. The inspection and repair procedure must match the car.

Test Before Replacing Parts

A harsh ride, uneven stance or warning message does not identify a single failed component. Check mechanical condition, leaks and the relevant diagnostic information before choosing a repair.

Why Specialist Rebuilding Matters

Because of this interconnected design, McLaren dampers cannot be treated like conventional shock absorbers. The internal valve assemblies, seal tolerances, and gas charges must be precisely matched to maintain the hydraulic balance across all four corners.

Twin-chamber hydraulic design requires specialist disassembly and reassembly
Internal gas-filled accumulators must be recharged to exact factory specifications
Adaptive damping flow restrictors control comfort, sport, and track modes
Electronic sensors and ride height calibration must be verified post-install
Cross-linked hydraulic circuits mean all four dampers must function in harmony

Frequently Asked Questions

Is An Exchange Damper Available For My Car?

Send us the VIN, suspension specification and symptoms. We confirm the matching part, exchange terms and lead time before booking. Availability is not guaranteed for every model.

Why Check Springs For Corrosion?

Corrosion or damage can weaken a spring. Inspect its condition and seating, and confirm suitable replacement parts when needed.

What Does Refurbishment Include?

The unit is assessed for suitability and the required internal work. The parts replaced, testing and any limits are confirmed for the particular damper.

Can You Assess Front Lift Problems?

Yes. Tell us the symptoms and confirm whether the car has front lift. Leaks, electrical faults and component condition need to be investigated before a repair is chosen.

How Do I Know Whether A Damper Needs Work?

Leaks, warning messages or a change in ride quality justify an inspection. They do not, on their own, prove that a damper or accumulator needs replacement.

McLaren Suspension Problems?

Send us your model year, mileage and symptoms. We will discuss the inspection needed and arrange an appointment at Foreign Automotive in Kitchener.
