Febi 03935 Wheel Suspensions

The Febi 03935 Wheel Suspension Control Arm is a high‑performance component designed for the front upper axle of Mercedes-Benz vehicles, particularly the SL Cabriolet and W114/W115 series. This part replaces the original OEM control arm (also known as the “triangle link” or “wishbone”) with superior materials and precision engineering to enhance handling, durability, and ride quality.

Key Features

• Material & Construction: Made from high‑strength steel alloy, the arm offers excellent fatigue resistance while maintaining a lightweight profile. The surface is treated with anti‑corrosion coating to protect against harsh road conditions.
• Exact OEM Match: The part number 03935 matches the original equipment specification for Mercedes-Benz models such as the SL Cabriolet, W114, W115, and R107 series. This ensures a perfect fit without modification.
• Integrated Bushings & Joint: Each arm comes with pre‑installed bushings and a universal joint, reducing assembly time and guaranteeing optimal alignment from the moment of installation.
• Lock Nut Included: A secure lock nut is provided to maintain tension on the control arm, preventing loosening over time and ensuring consistent suspension geometry.
• Enhanced Geometry: The design incorporates a slightly altered angle compared to the stock part, providing improved steering feel and reduced tire wear under aggressive driving conditions.

Compatibility & Installation

The Febi 03935 is engineered for the following Mercedes-Benz models:

• SL Cabriolet (W114/W115)
• R107 series (C107, R107)
• 8 Series (W114/W115)

Installation steps are straightforward and can be completed by a skilled mechanic or an experienced DIY enthusiast:

1. Remove the Old Control Arm: Detach the existing arm using standard tools, ensuring all bolts and nuts are properly accounted for.
2. Position the New Arm: Align the Febi 03935 with the mounting points on the chassis and steering knuckle. Verify that the bushings sit flush against the suspension components.
3. Tighten Fasteners: Secure all bolts to the specified torque settings, then install the lock nut to maintain tension.
4. Check Alignment: Perform a quick visual inspection and, if available, use an alignment tool to confirm that the suspension geometry matches OEM specifications.

Performance Benefits

• Improved Handling: The robust construction reduces flex under load, giving drivers a more responsive steering feel and tighter cornering capability.
• Longer Component Life: With high‑quality bushings and corrosion protection, the arm withstands road debris, salt, and extreme temperatures better than many aftermarket alternatives.
• Consistent Ride Quality: The precise geometry ensures that the suspension maintains its intended camber and toe settings, preserving tire contact patches for optimal grip.
