TRQ Front Upper Forward Tension Control Arm Passenger Side - Direct

In this review the TRQ Front Upper Forward Tension Control Arm for the passenger side is assessed for drivers who need a direct replacement part for 4Matic Mercedes models. The bottom line: this control arm is for DIY mechanics and independent shops that want a pre-assembled, direct-fit replacement that mirrors OE fit and finish. Our review finds it best where fit accuracy and ease of installation matter most, and where value-conscious buyers appreciate a part that arrives ready to install with clear compatibility for several E and CLS 4Matic model years.

Key Features

• Direct fit replacement: Pre-assembled to match the original geometry so installers can swap it in without modifications for a secure fit.
• Wide compatibility: Lists fitment for multiple model years including E350, E550, CLS550 and CLS400 4Matic variants so buyers can confirm fit against their vehicle.
• Trusted reference numbers: Multiple reference numbers are provided so technicians can cross-check parts catalogs and confirm compatibility quickly.
• DIY support: The brand emphasizes DIY videos and installation guidance which helps independent installers and home mechanics view before they do the job.
• Durability focus: Built as a replacement control arm intended to replicate the original component's strength for suspension stability and long service life.

Who It's For

This control arm is aimed at owners of 4Matic Mercedes E and CLS series who need a passenger-side front upper forward replacement and prefer a part that fits without extensive adjustment. It is especially useful for DIYers who value video support and for independent shops looking to source a cost-effective direct-fit replacement.

Those who should look elsewhere include buyers who require a brand-new factory OEM numbered part for warranty parity or drivers needing a custom or performance-tuned suspension component; this is a like-for-like replacement part rather than an upgrade part.

Pros & Cons

Pros

• Good fit with many customers reporting the part matches original components closely.
• Pre-assembled design saves installation time and reduces the need for alignment of subcomponents.
• Strong value proposition compared with dealer-sourced parts for the same applications.

Cons

• Some customers have reported ball joint issues, so inspecting the joint on delivery is recommended.
