Product Description
High-quality Front Left Upper Control Arm 4M0 407505B for Audi Q5L & Q8
This premium integrated front left upper control arm with OE number 4M0 407505B is a core vulnerable five-link chassis component for Audi Q5L and Q8 luxury SUVs. It enjoys steady global aftermarket demand and continuous repeated bulk orders, widely stocked by European luxury car repair garages and cross-border auto parts wholesalers worldwide.
Core Selling Points
High-consumption chassis wearing part suitable for one-stop bundled procurement
Front upper control arms are the most frequently replaced suspension parts on Audi premium models. Under long-term bumpy road vibration, repeated steering swing, cold-hot temperature alternation and mud/salt erosion, the original arm will suffer rubber bushing aging cracking, ball joint loose clearance, arm body deformation and corrosion.
Worn control arms lead to obvious clunking noise over speed bumps, vague steering feedback, serious uneven tire wear, loose chassis feeling at high speed, and accelerated damage to wheel bearings and shock absorbers. Most buyers purchase left & right paired control arms together with tie rods, stabilizer links to cut procurement and logistics costs, bringing stable profit margins and low inventory risks for dealers.
100% OE identical specification, direct bolt-on installation without modification
Manufactured strictly in accordance with Audi OEM technical standards: overall forging outline, mounting hole spacing, ball joint angle, bushing size, bolt positioning dimension and swing geometry are fully consistent with genuine 4M0 407505B. Matched right counterpart OE code: 4M0 407506B.
No cutting, bending or positioning adjustment is required during replacement; perfectly fits the original five-link front suspension structure, greatly shortening chassis disassembly and four-wheel alignment maintenance hours.
Compatible Vehicle Range
- Main Fit Models: Audi Q5L (80A chassis, 2018 onwards), Audi Q8 (4M chassis)
- Extended Applicable Models: Q7, A6L C8, A7, SQ5 and other models sharing the same MLB Evo platform suspension
- Fit Type: Front Left Driver Side Upper Straight Control Arm
Reinforced Durable Structural Design
- High-strength forged aluminum alloy arm body: lightweight, high rigidity, anti-deformation and anti-corrosion, effectively reduce unsprung weight for better handling
- Integrated sealed ball joint: filled with long-life grease, dust-proof & waterproof design, no clearance looseness for long service life
- High-density natural rubber suspension bushing: calibrated OEM hardness, excellent vibration filtering performance, anti-aging and anti-cracking under long-term compression
- Precise hole position tolerance: consistent with original installation data, no deviation after assembly, convenient four-wheel alignment
- Whole set pre-assembled finished product: ready to install directly, no extra assembly work needed
Restore Precise Steering & Solid Chassis Texture
As the key guiding part of front five-link suspension, it limits wheel swing track during steering and bump passing. Effectively filter road vibration, eliminate loose chassis sensation, restore precise steering response at high speed, slow down eccentric tire wear, and comprehensively protect the whole front suspension system.
Fully Resolve Typical Suspension Failure Symptoms
- Obvious banging/clunking noise when crossing potholes and deceleration strips
- Steering vague, wandering easily during high-speed driving
- Severe unilateral tire inner/outer eccentric wear
- Loose chassis feeling, vehicle shaking during emergency braking
- Ball joint gap causes abnormal tire deflection, affecting driving safety
Rigorous Multi-stage Factory Testing & Ample Spot Inventory
Each control arm undergoes fatigue swing test, rubber aging cycle test, ball joint tightness detection and salt spray anti-corrosion test before delivery, complying with IATF 16949 international automotive quality management standards.
