How to Install Coilovers on the AMG GT 53 (2019-2023)

Learning how to install coilovers on the 2019-2023 Mercedes-AMG GT 53 is the single fastest way to sharpen the handling of AMG's 429-horsepower, 4,600-pound four-door. The GT 53 leaves the factory riding on AMG Ride Control adaptive dampers tuned for grand touring, so lowering the car and adding real damping control transforms body roll, turn-in, and stance. This guide from our Tampa, FL shop walks through the two suspension paths NLP Performance stocks for the X290 chassis – the motorsport-grade Bilstein Evo R coilover and the KW Height Adjustable Spring kit – then covers tools, the step-by-step install, torque and alignment.

What You Are Working With: The AMG GT 53 (X290)

The Mercedes-AMG GT 53 4-Door Coupe is a 429-horsepower, all-wheel-drive performance sedan built on the X290 platform. Power comes from a 3.0-liter M256 turbocharged inline-six paired with EQ Boost, a 48-volt mild-hybrid starter-generator that adds a temporary 21 hp and 184 lb-ft of low-end torque. The car makes 429 hp and 384 lb-ft, drives all four wheels through AMG Performance 4MATIC+, and hits 60 mph in roughly 4.4 seconds while weighing about 4,600 pounds.

That weight and the factory grand-touring damper tune are exactly why suspension is the highest-value first mod. The GT 53 ships with AMG Ride Control adaptive dampers, so any coilover decision hinges on one question: do you keep those electronic dampers, or replace them? That single choice determines your parts, your labor time, and whether you need a control-module delete – so we cover it first.

Bilstein Evo R vs KW H.A.S.: Which Path Fits Your Build?

Choose the Bilstein Evo R if you want full coilover adjustability and track capability; choose the KW Height Adjustable Spring (H.A.S.) kit if you want a lower stance while keeping the factory adaptive dampers. The Evo R is a complete 2-way coilover that replaces the OEM struts, offering independent compression and rebound tuning with 100 setting combinations plus adjustable monoball upper mounts for camber. The KW H.A.S. is a height-adjustable spring system that bolts onto your existing dampers, so AMG Ride Control keeps working and there is no dash warning to suppress.

The Bilstein Evo R Coilover (Top Pick for Performance)

The Bilstein Evo R is a motorsport-derived 2-way coilover engineered specifically for the demanding conditions of track use. Its independent compression and rebound adjustment gives 100 distinct damping combinations, so you can dial in a compliant street setting or a stiff track setup from the same kit. Monotube damper construction sheds heat better than the twin-tube OEM units, and the adjustable monoball upper mounts let you set negative camber for grip. Because it uses passive dampers, GT 53 cars fitted with AMG Ride Control may set a suspension warning – plan for a control-module delete or confirm requirements for your VIN before install.

The KW H.A.S. Kit (Keep Your Adaptive Dampers)

The KW Height Adjustable Spring kit is the simplest way to lower a 2019-2021 AMG GT 53 (and 2021-2022 GT 43) because it reuses the factory dampers. Instead of fixed-drop lowering springs, the H.A.S. system uses a threaded, height-adjustable spring perch so you set the exact ride height per axle within KW's published range. Since the OEM electronic dampers stay in place, AMG Ride Control and its comfort/sport modes continue to function normally and there is no fault light to code out. It is the lower-cost, lower-complexity route for owners who want stance and a modest handling bump without touching the dampers.

Tools and Parts You Will Need

Plan on a full metric socket and wrench set, a torque wrench, and a two-post lift or four sturdy jack stands before you start. A coilover install on an all-wheel-drive AMG is a corner-by-corner job, and skipping the right tools is how fasteners get rounded or under-torqued.

• Metric sockets and wrenches (10-21mm), plus E-Torx sockets for MB strut hardware
• Click-type torque wrench (up to ~150 lb-ft) for final fastener torque
• Two-post lift or a floor jack with four rated jack stands and wheel chocks
• Spring compressor (only if transferring OEM upper hardware – the Evo R ships assembled)
• Tape measure for recording fender-to-hub ride height at each corner
• Anti-seize and a breaker bar for the strut-to-knuckle bolts
• Your chosen kit: Bilstein Evo R or KW H.A.S.

Step-by-Step Coilover Install

A coilover install on the AMG GT 53 takes an experienced DIYer 6-9 hours and a professional shop roughly 4-6 hours of labor, not counting alignment. Work one corner at a time, keep the opposite side supported, and torque every fastener to the factory specification.

1. Prep and lift the car

Park on level ground, chock the wheels, and break the lug bolts loose before lifting. Raise the car on a two-post lift or at the factory pinch-weld points with rated jack stands, then remove all four wheels. Before anything comes apart, measure and write down the fender-to-hub-center height at each corner so you have a baseline to lower toward.

2. Remove the front struts

Disconnect the sway bar end link, unclip the ABS wheel-speed sensor line and brake hose from the strut bracket, and support the lower control arm. Remove the strut-to-knuckle bolts, then the upper strut mount nuts in the cowl area, and lower the assembly out. On AMG Ride Control cars, unplug the damper control connector and retain it for the delete module if you are fitting the passive Evo R.

3. Install the new front units

Set your target front ride height on the Evo R perch (or thread the KW H.A.S. spring perch) before installation to save time. Bolt the upper mount into the cowl, guide the lower body into the knuckle, and start all fasteners by hand before torquing. Reconnect the sway bar link, sensor lines, and brake hose so nothing is left dangling.

4. Repeat at the rear

The rear of the X290 separates the spring and damper on the KW kit, while the Evo R uses a combined rear unit; follow the kit-specific instructions. Support the rear lower arm, remove the OEM hardware, and fit the new spring or coilover at your chosen height. Reconnect the rear sway bar links and any sensor brackets.

5. Torque, roll, and re-measure

Torque all suspension fasteners to the factory values and set the wheel bolts to roughly 110-130 lb-ft (150-175 Nm) – always confirm against the AMG service spec. Lower the car, roll it back and forth several car lengths to settle the suspension, then re-measure each corner and fine-tune the height before the alignment.

Corner Balancing and Alignment

Every AMG GT 53 needs a professional four-wheel alignment immediately after a coilover install, because lowering the car changes camber, caster, and toe. Driving on fresh coilovers before alignment scrubs tires quickly and dulls the handling you just paid for. Set camber and toe to a fast-road or track spec, and for a track car have the shop corner-balance the chassis so weight is even diagonally – the Evo R's adjustable perches make this possible. Budget for the alignment as a separate line item; it is not optional on a 4,600-pound AWD sports sedan.

Upgrade the Brakes While It Is on the Lift

With the wheels already off for the coilover install, it is the ideal time to refresh the rear brakes on your AMG GT 53. The car's mass and speed punish factory pads and rotors, and swapping them now saves a second teardown. The Brembo OE Rear Disc Brake Kit ($334.34) bundles matched rear rotors and Low-Met pads for a direct OEM-quality replacement, while the DBA Street Series rear pads ($53.65) are a budget-friendly, low-dust upgrade for iron-rotor cars.
