Silver's NEOMAX Coilovers

2014-2021 Mercedes C Class C400/C43 AMG (W205) AWD With Air Ride

Silver’s NEOMAX Coilovers for the 2014-2021 Mercedes C Class C400 and C43 AMG (W205) AWD with factory Air Ride are built for owners who want a true performance suspension and a clean way to move away from the complexity of the OEM air system. If your W205 came equipped with air suspension from the factory, you already know the benefits when it is working right, smooth ride, automatic leveling, and a refined feel. You also know the downside as the miles add up: leaks, sagging corners, compressor issues, and warning lights can turn into an expensive cycle. This NEOMAX kit is designed as a complete coilover conversion for air ride equipped cars, replacing the air suspension hardware with a traditional spring and damper setup that is more consistent, more tunable, and often far more straightforward to maintain long term.

At the heart of NEOMAX is a monotube shock design engineered to deliver both control and comfort, not just a harsh lowered ride. Silver’s uses a 44mm piston and digressive style valving characteristics to provide strong low speed damping response. That low speed control is what you feel in the driver’s seat when you turn in, transition through corners, or brake hard and want the chassis to stay composed. Digressive style characteristics help the suspension support the car during chassis movement while still allowing compliance over real road imperfections, so the car can feel planted without feeling punishing. The monotube design also increases shock oil capacity and displacement compared to many twin tube layouts, which is a key advantage when you want consistent performance during longer drives, heat buildup, and aggressive use.

Fine tuning is built in. NEOMAX features 24 levels of damping adjustability, allowing you to tailor ride and handling for your exact needs. You can set the car up for a comfortable daily street feel, then firm it up for sharper response when you want more feedback and reduced float. Silver’s pairs this adjustability with high grade shock oil and high viscosity IP F.A. 5W damper oil to help keep damping consistent and efficient. This matters because a suspension kit is only as good as its repeatability. When you dial in your settings, you want the same response day after day, not a setup that changes personality after a long drive or a temperature swing.

The structural pieces are designed for durability and confidence. The kit uses a high strength JIS G3445-STKM13C (DIN2393-ST44-2) carbon steel 52mm diameter seamless shock tube. That robust foundation supports the damper internals and helps the suspension maintain precise motion control under load. Where applicable on McPherson style front applications, Silver’s includes adjustable T6 6061 aluminum front camber plates, giving you a meaningful alignment tool that helps you dial in tire contact and turn in response. Camber adjustability is especially valuable if you plan to run wider wheels and tires, drive aggressively, or want more consistent cornering grip. On those applicable McPherson applications, the kit also includes a Koyo Japan radial bearing upper spring perch. This is a smart detail that reduces spring bind, helps eliminate unwanted noise, and improves steering feel by allowing smoother spring rotation during steering and suspension movement.

Ride height adjustment is handled correctly using the lower bracket. That means height changes are made at the bracket instead of forcing you to rely on spring perch adjustments or preload changes to drop the car. The advantage is simple: you keep maximum possible travel regardless of height setting, and you avoid compromising damper stroke just to get the stance you want. This approach also makes it easier to set the car where you want it, then fine tune without chasing preload side effects. The springs are cold-bent from high strength SAE9254 steel to maintain a stable elastic modulus and long term durability. Default spring rates are Front 14K and Rear 12K-S, providing a performance oriented baseline that pairs well with the damping adjustability so you can balance comfort and response.

Silver’s also paid attention to the install details so the finished result looks and fits right. The kit includes powder coated steel lower brackets that match factory brake line and ABS wire tabs for a clean, seamless installation. On applicable multi link suspension systems, NEOMAX uses anodized T6 6061 aluminum lower mounts to reduce unsprung weight. Reducing unsprung weight helps the suspension react faster to bumps and road texture, which can improve both grip and ride quality. It is the kind of detail that separates a basic lowering solution from a properly engineered system.

Because this kit is specified for W205 AWD models with factory air ride, it is intended as an air suspension replacement conversion. In other words, the air components are removed and the car is converted to a conventional coilover suspension. That is often exactly what owners want when the factory air system becomes costly or unreliable, because it simplifies the suspension and gives you direct mechanical control over height and damping. Since vehicle electronics can vary by trim and options, some vehicles may require additional steps to prevent factory air suspension warnings or errors after conversion. That can involve coding, modules, or resistors depending on the vehicle configuration. Those solutions are typically separate from the coilovers themselves, so it is important to plan for the electronic side if your specific setup demands it.

Every NEOMAX kit is built to deliver a more connected and confidence inspiring feel, whether your goal is a refined daily ride with better body control or a more aggressive street setup with sharper response. You gain the ability to set your ride height precisely, tune damping for your roads and tires, and reduce the long term dependency on air suspension components. Backed by a 5 year limited manufacturer’s warranty, NEOMAX is a strong option for W205 owners who want performance, consistency, and a suspension system that is built to be driven.
