Front Steering & Suspension Kit for 2012-2015 Mercedes E350/E400 - 10

In this review of the TRQ front steering and suspension kit, the conclusion is straightforward: this 10 piece OE replacement set is aimed at owners of 2012-2015 Mercedes-Benz E350 and 2015 E400 4Matic models who need a full front suspension refresh without sourcing individual parts. The kit replaces control arms, tie rods, sway bar links and ball joints with direct-fit components, and the single biggest reason to buy is the convenience of a vehicle-specific, one-box replacement that restores steering feel and alignment potential at a fraction of dealer cost.

Key Features

• Direct Fit: Parts are supplied to match OE geometry so installation aligns with factory mounting points for a straightforward swap.
• Complete 10 Piece Kit: Includes inner and outer tie rods, lower and upper control arms with ball joints, and sway bar links so the entire front steering and much of the suspension linkage is renewed at once.
• OE Reference Compatibility: The kit cross-references multiple OE numbers so it fits the specified Mercedes-Benz front-end configurations without guesswork.
• Application Specific Design: No modifications are required for the listed 4Matic models, reducing installation time for a typical DIYer or independent shop.
• Cost Efficiency: Buying the set at once tends to be more economical than replacing individual components sequentially and helps ensure matched wear across parts.

Who It's For

This kit is best for owners of 2012-2015 Mercedes-Benz E350 4Matic (wagon and sedan) and 2015 E400 4Matic sedan who need a front suspension overhaul and want a matched set of components. It fits vehicles without electronic control steering and is intended for people comfortable checking fitment and doing a professional or competent DIY installation.

It is not the right choice for cars with electronic control steering, for owners who only need a single part replaced, or for those who require upgraded performance parts; those users should seek individual OE or performance components instead.

Pros & Cons

Pros

• Quality and fit are frequently praised, making reassembly and alignment straightforward for many installers.
• Comprehensive kit replaces multiple wear items at once, restoring steering response and reducing future troubleshooting.
• Good value for money compared with buying OEM pieces separately or paying dealer labor for multiple visits.

Cons

• Some customers reported concerns about ball joint longevity, so long-term durability may vary by use and driving conditions.
• Occasional reports of missing hardware on shipment mean buyers should inventory the box before starting the job.
