A1643202431 Rear Air Suspension Shock Strut for Mercedes-Benz W164 ML280 ML300 ML63 AMG GL320 GL300 GL350(2006-2010)
Original OE Number: A1643202431
Product Name: Mercedes‑Benz Rear Shock Absorber, Rear Suspension Damper, Chassis Hydraulic Shock Assembly, Rear Wheel Damping Shock Absorber (Non‑ADS standard hydraulic version)
Installation Position: Rear wheel, universal for left and right sides. Core damping component of chassis suspension system. It absorbs road bumps, suppresses body bouncing, attenuates vibration and stabilizes vehicle posture, improving driving smoothness and riding comfort. It is a regular wear‑prone maintenance part for Mercedes‑Benz ML / GL class chassis.
Product Description
A1643202431 is an original‑equipment equivalent rear hydraulic shock absorber specially for Mercedes‑Benz W164 / X164 chassis. It is the standard hydraulic version without ADS adaptive suspension. As the core damping part of suspension system, it absorbs road vibration effectively, reduces body roll during cornering and floating shaking at high speed, relieves brake nosedive and bumpy loose feeling, greatly upgrading driving quality, handling stability and riding comfort.
Original shock absorbers on W164 / X164 suffer long‑term road impact, temperature alternation, sediment and water erosion plus frequent stretching‑compression work. Internal hydraulic oil ages, oil seal wears leading to oil leakage and damping failure. Typical symptoms: rear end sag, uneven body height left‑right, excessive bouncing over speed bumps, loose chassis noise, floating feeling at high speed, large body roll in cornering, obvious brake dive, abnormal tire noise and poor comfort. Failed shocks will accelerate wear of suspension bushings, control arms and tires, trigger sequential damage of chassis parts and raise later maintenance cost.
This A1643202431 rear shock absorber is 1:1 manufactured according to original OE parameters. Tube diameter, stroke, damping coefficient, mounting holes, bushing dimension and bolt positions fully comply with OEM standards. Adopted high‑strength seamless cylinder tube, high‑temperature resistant hydraulic oil, heavy‑duty dust‑proof oil seal and thickened anti‑rust piston rod. Features stable damping, excellent impact resistance, anti‑leakage and long service life. This is pure hydraulic non‑ADS version. Direct bolt‑on installation without coding, adaptation or chassis modification. Perfect replacement for original unit. After installation, it thoroughly solves bouncing, chassis rattle, high‑speed floating and poor comfort, restores tight chassis texture and stable handling. Low rework rate, ideal for repair shop service, auto parts wholesale and cross‑border export.

Interchange Remark: Above numbers are iterative interchangeable part numbers for W164/X164 rear standard hydraulic shock absorbers. Identical mounting dimension, damping parameter and interface structure. Direct non‑destructive replacement without chassis modification.
Q1: Which Mercedes‑Benz vehicles fit A1643202431? A: Fits 2005‑2011 Mercedes‑Benz W164 ML‑Class and X164 GL‑Class with non‑ADS standard hydraulic suspension. Not for ADS adaptive damping or air suspension trims.
Q2: Is there left‑right distinction for this shock absorber? A: Universal for rear left and right. Single unit fits both sides, easy stock management with high compatibility.
Q3: Can it be installed on vehicles equipped with ADS adaptive damping? A: Not applicable. This is pure hydraulic mechanical version without electronic adaptive function. It cannot match ADS ECU system and will trigger malfunction and mismatched damping stiffness.
Q4: Does programming or coding need after replacement? A: No programming or coding required. Pure mechanical‑hydraulic structure, direct in‑situ replacement.
Q5: What symptoms require shock absorber replacement? A: Shock oil leakage, excessive bouncing over speed bumps, loose chassis rattle, floating feeling at high speed, large corner roll, severe brake nosedive, low rear‑end height and abnormal tire wear. Replacement is strongly recommended once above symptoms occur.
Q6: Can I replace only one single shock? A: Pair‑replacement for left & right rear shocks is recommended. Different damping performance between old and new units may cause body tilt, offset, abnormal noise and inconsistent handling.
