OE-spec gas-charged damper engineered for the Mercedes-Benz W166 platform — ML-Class (2012–2015) and GLE-Class (2015–2019). Restores factory ride control, braking stability and tyre contact after mileage-related wear or leakage. Sold per side — select Front Left/Right or Rear Left/Right.
What this is / isn’t:
-
Included: 1× shock absorber
-
Not included: Coil spring, top mount/bearing, bump stop/dust boot, hardware, air bellow or compressor.
-
Important: Choose the correct version for Standard steel-spring suspension. Vehicles with AIRMATIC require air struts, not this part.
Key Features:
-
OE-Matched Damping Curves: Correct compression/rebound rates for W166 chassis/engine weights.
-
Gas-Pressurised Design (mono/twin-tube as supplied): Consistent, fade-resistant performance over rough roads.
-
Exact Fitment: Correct mounting eyes/pins, rod length and body diameter — no modifications.
-
Quiet NVH: Low-friction seals and precision guides reduce knock/rattle over sharp bumps.
-
Corrosion Protection: Phosphate/painted body with hardened chrome piston rod for long service life.
Compatibility:
-
ML-Class (W166) — 2012–2015 (ML250/300/350/400/500/63 AMG**)
-
GLE-Class (W166) — 2015–2019 (GLE250/300/350/400/500/63 AMG**)
-
GL/GLS (X166) — many variants share the same dampers* (verify by VIN/OE).
-
Drivetrain: 4MATIC and 2WD where applicable (spec can differ — match by VIN).
-
Suspension options:
-
Standard steel-spring → use this damper.
-
AIRMATIC (air suspension) → different air strut assembly (not this item).
-
AMG/Sport packages may use specific rate dampers — select the AMG/Sport option if listed.
-
Typical OE Reference Families (guide only):
Front: A166-320-… | Rear: A166-323-…
(AMG/AIRMATIC have unique numbers.) Order by the exact OE number on your vehicle or confirm via VIN.
Symptoms of Worn Shocks:
-
Bouncy/floaty ride, nose-dive on braking, rear squat on acceleration
-
Steering shimmy, unstable cornering, or poor towing stability
-
Oil misting/leaks on damper body; clunk over bumps; cupped tyre wear
Installation Notes (Pro Tips):
-
Replace in axle pairs (both fronts or both rears) for balanced handling.
-
Torque suspension fasteners at ride height to prevent bushing preload.
-
Renew top mounts, bump stops, dust boots if cracked or noisy.
-
After fitting, perform a wheel alignment if front components were disturbed.
-
For AIRMATIC vehicles: do not mix with steel-spring dampers; air struts are a different assembly.
What’s Included / Not Included:
-
✅ 1× Shock absorber (choose Front/Rear and Left/Right)
-
❌ Coil spring, mount/bearing, bump stop, dust boot, hardware, air components
Q&A
Q1: How do I know if I have AIRMATIC?
Look for an air line at the strut and ride-height controls on the dash. If present, you need air struts, not conventional shocks.
Q2: Will this fit my X166 GL/GLS?
Many do on matching engines/suspension. Confirm by VIN/OE number before ordering.
Q3: Can I install these at home?
Yes, with standard tools. Use new self-locking nuts/bolts where specified and tighten at curb height.
Q4: Do I need wheel alignment?
Recommended after front damper replacement to maintain tyre life and steering feel.
