Fits: 2011-2023 Mercedes-Benz M-Class.
This F2 Function & Form Type 4 coilover kit (part number 45301611) is made for the Mercedes-Benz M-Class W166. The fit list covers the 2011-2023 M-Class.
Type 4 coilovers are height-adjustable and built to order for your specific chassis, not pulled from a warehouse shelf. For a W166 owner, that means a kit matched to the platform with adjustable ride height.
Built-to-order lead times apply, so check the listing for details. Select your vehicle on the page to confirm fit, or call 813-535-5801 and we will help you place the right F2 tier for your build.

Ride height is set on the threaded body or the lower mount, and the damping (how firm the shock feels) with the adjuster when the kit has one. Some kits also let you set spring preload and camber at the top mount. The Part details above list what this exact kit adjusts.
Yes. Changing ride height changes camber and toe, so have the car aligned once the height is set and the suspension has settled after a short drive.

The car settles a little over the first few drives. After that, re-check the ride height, the lock rings on the collars and the top-mount hardware, then get the alignment done.

Install and care: coilovers
Before you start
- Read the maker's guide and note the recommended ride-height range for your car.
- Book an alignment for after the install; the car needs one.
Do
- Set all four corners to the same drop before the alignment and re-check the height after the first drive.
- Keep the threads clean and lightly lubricated so the collars still turn next season.
Don't
- Don't go lower than the maker's range; it costs ride quality and tire life.
- Don't skip the alignment.
