Product Details
The Function and Form Type 3 Coilovers for the 2011+ Mercedes-Benz M-Class (W166) are the brand's track-focused performance coilover, designed for Mercedes-Benz M-Class drivers who push hard at the track but still drive the car on the street. These M-Class coilovers are built around a digressive monotube damper and world-famous Eibach ERS Motorsport springs, giving the M-Class W166 race-bred body control with the flexibility to set it up your way.
Known to enthusiasts as Function & Form or F2 Suspension, the Type 3 offers customizable spring rates so you can run a comfortable street setup one weekend and a stiffer track alignment the next. One-way adjustable damping and full-length ride-height adjustment let you fine-tune how the W166 M-Class rides and handles, all in a rebuildable, preload-ready kit. Backed by a 24-month warranty with free U.S. shipping on orders over $250.
