Front Control Arm with Ball Joint Set for 2012-2015 Mercedes C250 C300

In this review the reviewer found the TRQ four piece control arm set to be a practical OE replacement for owners of specific Mercedes-Benz models from 2008 through 2016. The bottom line: this kit is for DIY mechanics and independent shops who need a direct fit, vehicle specific replacement that restores suspension geometry without sourcing individual parts. The review highlights fitment accuracy and included ball joints as the single biggest reason to choose this kit, while advising buyers to confirm their exact model and production date against the listing fitment information before purchase.

Key Features

• Direct Fit: The kit is designed as a direct OE replacement so installation aligns with factory mounting points to reduce alignment work.
• Complete Four Piece Kit: Includes two front forward lower control arms and two front rearward upper control arms, each with ball joints, providing a full front suspension refresh in one purchase.
• OE Reference Compatibility: Matched to multiple OE reference numbers so it integrates cleanly with the vehicle's existing suspension components.
• Vehicle Specific Fitment: Fitment notes cover model and production date ranges, helping buyers confirm compatibility with C250, C300, C350, E350 and SLK variants.
• Aftermarket Cross References: Multiple aftermarket and OEM cross reference numbers are provided to aid verification and installer confidence.

Who It's For

This control arm set is aimed at Mercedes-Benz owners and independent mechanics who need a matched set for front suspension repairs on 2008-2016 C and SLK models and certain E350 applications. It suits anyone who prefers replacing all front control arms with ball joints at once to ensure even wear and consistent handling.

It is not ideal for buyers who have vehicles outside the listed fitment ranges or those seeking performance aftermarket pieces with altered geometry. Also, buyers who require factory-authorized stamped parts should compare OE dealer options before deciding.

Pros & Cons

Pros

• Complete matched kit simplifies installation by supplying both lower and upper front control arms with ball joints.
• Direct fit construction reduces the need for modification and generally speeds up reassembly and alignment.
• Good value compared with sourcing individual arms and ball joints separately, based on price-to-quality feedback from users.

Cons

• Some users have reported concerns about long term durability of the ball joints versus OE units, so monitoring early miles is advised.
