This pair of front upper control arms from OUSIMY serves as a direct OEM replacement suspension kit built for Mercedes-Benz W212 chassis vehicles produced from 2010 to 2018. Mounted on the front upper suspension assembly, these control arms connect the steering knuckle to the vehicle frame, stabilizing wheel positioning, smoothing out bump absorption, and maintaining precise steering geometry during daily driving and highway cruising.
Basic Product Details
This two-piece left and right upper control arm set is forged from high-density aerospace-grade aluminum alloy with integrated pressed rubber bushings and pre-installed sealed ball joints. Designed exclusively for the front upper suspension position, it matches all factory mounting hole positions and bolt dimensions, fully compatible with all W212 platform Mercedes-Benz models spanning the 2010 through 2018 production years with zero structural modifications required during fitting.
Core Product Advantages
We reinforce the arm body with precision forging to eliminate the factory original weakness of thin aluminum prone to bending under heavy load and rough road conditions. The embedded bushings use multi-layer anti-aging natural rubber that resists cracking and deformation from extreme temperature swings. Sealed grease-packed ball joints lock out road grime and moisture to prevent premature wear and play. Every component adheres strictly to OEM dimensional standards for plug-and-play bolt-on installation, cutting down labor time for professional repair shops and DIY vehicle owners alike.
Solvable Common Vehicle Pain Points
Worn or bent factory upper control arms trigger well-documented W212 suspension issues including persistent clunking and rattling noise when turning or driving over potholes, loose and vague steering feedback, uneven front tire tread wear, vehicle pulling to one side during acceleration or braking, and gradual degradation of ride comfort. Many drivers end up replacing single arms repeatedly due to cheap aftermarket part failure; this matched pair fully refreshes the front upper suspension and eliminates recurring suspension troubles permanently.
Corresponding OBD & VCDS Fault Codes
Installing this replacement control arm set resolves diagnostic trouble codes triggered by misaligned front suspension geometry and faulty wheel position feedback: C1122 (Front Left Suspension Height Implausible), C1123 (Front Right Suspension Height Implausible), C1517 (Steering Angle Sensor Offset Out of Range) and other chassis alignment error codes stemming from damaged upper control arm assemblies.
Logistics & Shipping Benefits
Complimentary free shipping is provided for all orders shipped within the United States. All in-stock control arm kits are packaged and dispatched within 24 business hours from domestic US warehouses, allowing you to complete suspension repairs quickly and restore stable vehicle handling without lengthy waiting periods.
Value Added Warranty & DIY Installation Support
Each OUSIMY front upper control arm kit is backed by a multi-year manufacturer warranty to cover any manufacturing defects. Pre-assembled with all required sealed joints and bushings, the kit requires no extra parts or specialized programming after installation. Basic hand tools are sufficient to finish the swap, making the repair process accessible for home mechanics following standard Mercedes-Benz service procedures.
