TRQ Front Forward Lower Control Strut Arm LH for S Class - Direct Fit

In this review the TRQ Front Forward Lower Control Strut Arm for the driver side (LH) is evaluated as a direct replacement for Mercedes S and CL class models. The bottom line: this control arm is for owners who need an OE-style, vehicle specific suspension part that restores steering geometry without aftermarket guessing. It installs as a direct fit on many 2007-14 S and CL variants and the review focuses on fit, construction, and the one area buyers should inspect closely before and after installation.

Key Features

• Direct Fit: Arrives ready to install for the listed model years and avoids modifications, saving time in the garage.
• OE Replacement Assembly: Includes the control arm and ball joint assembly so the suspension is rebuilt to the original configuration.
• Vehicle Specific Fitment: Clear compatibility with 2007-14 Mercedes S550, S63, S600, S65, S400 and CL models reduces the chance of ordering the wrong part.
• Aluminum Construction: Lightweight aluminum arm helps maintain original handling characteristics and resists corrosion compared with plain steel.
• Bushings Included: Arrives with bushings installed so the part is ready for use and reduces the number of additional parts to source.
• OE Reference Numbers: Uses known OE references such as 2113304307 to aid in crosschecking fitment with dealer or vehicle records.

Who It's For

The TRQ lower control arm is aimed at Mercedes owners and independent shops repairing front suspension on S and CL class vehicles from the late 2000s to early 2010s who want a direct OE replacement without custom fabrication. It is especially useful when the original control arm or ball joint has failed and the vehicle needs restored alignment and ride quality.

It is not intended for drivers seeking upgraded performance components or adjustable suspension geometry; enthusiasts who want aftermarket tuning, adjustable arms, or greaseable ball joints should look at dedicated performance parts instead.

Pros & Cons

Pros

• Direct fit saves installation time and matches original mounting points.
• Aluminum construction offers a balance of strength and reduced weight for stock handling.
• Includes bushings and the ball joint assembly for a comprehensive replacement.
• Well documented OE and aftermarket reference numbers make compatibility checks straightforward.

Cons

• Some customers report ball joint issues, so inspect the joint on receipt and after initial miles.
• Non-adjustable and non-greaseable design may not suit those wanting serviceable or performance-tunable components.

Specifications

Our Verdict

The TRQ Front Forward Lower Control Strut Arm LH is a sensible, cost-effective OE replacement for S and CL class owners who need a reliable restoration of suspension geometry. It delivers proper fitment, solid aluminum construction, and the convenience of a complete assembly, making it good value for routine repairs; buyers should however verify the ball joint condition on delivery and consider serviceable alternatives if greaseable hardware is required.
