The Function and Form Type 4 M Class suspension coilover kit is a full air suspension delete system for the Mercedes-Benz W166 chassis (2011–2019 M-Class). Designed for reliability, better handling, and a lowered ride height, this kit eliminates the complex and failure-prone air system and replaces it with a performance-tuned coilover setup.\u003c\/p\u003e \u003cp\u003eThe OEM air suspension on the M-Class—especially models like the ML350 and ML550—is known for expensive repairs and recurring problems. Common symptoms include the vehicle sagging overnight, uneven ride height, noisy compressors, or the dreaded dashboard warning: “Airmatic malfunction – visit workshop.” Diagnostic codes like C1525-005, C1511-002, or C1516-008 often indicate leaks, compressor failure, or sensor issues, all of which can quickly add up in repair costs.\u003c\/p\u003e \u003cp\u003eThis Type 4 M Class suspension coilover kit is engineered as a direct-fit conversion for vehicles originally equipped with AIRMATIC. It completely removes the need for air struts, compressors, height sensors, and control modules. Instead, you get a robust, fully mechanical coilover system with precision-tuned spring rates, adjustable ride height, and superior reliability.\u003c\/p\u003e \u003cp\u003eEach kit features inverted monotube dampers, built to handle the weight and dynamic load of SUVs like the W166. The inverted design improves rigidity under side loads and reduces unsprung weight—resulting in better steering feel and sharper handling, whether you’re driving on the highway or carving through canyon roads.\u003c\/p\u003e \u003cp\u003eWith independent ride height adjustment via a threaded shock body, you can fine-tune your M-Class’s stance to your exact preference—lower it for aesthetics and improved cornering or raise it slightly for better clearance. Ride height adjustments do not affect spring preload or suspension stroke, preserving comfort and control across a wide range of settings.\u003c\/p\u003e \u003cp\u003eThe kit also includes SUV-specific spring rates optimized for daily driving with a firm, planted feel and reduced body roll. All components are powder-coated or anodized to withstand harsh weather and road grime, and the shocks are fully rebuildable for long-term service.\u003c\/p\u003e \u003cp\u003eThis is more than just a fix—it’s a complete upgrade to your M Class suspension, offering improved driving dynamics, long-term durability, and a cleaner, more aggressive look.\u003c\/p\u003e \u003cp\u003eKey Features:\u003c\/p\u003e \u003cp\u003eFull air suspension delete kit for W166 (2011–2019)\u003c\/p\u003e \u003cp\u003eReplaces AIRMATIC with coilover system\u003c\/p\u003e \u003cp\u003eEliminates air struts, compressor, sensors, and ECU\u003c\/p\u003e \u003cp\u003eInverted monotube dampers for SUV strength\u003c\/p\u003e \u003cp\u003eIndependent ride height adjustment (threaded body)\u003c\/p\u003e \u003cp\u003eSpring rates tuned for daily and spirited driving\u003c\/p\u003e \u003cp\u003eCorrosion-resistant finish (powder-coated + anodized)\u003c\/p\u003e \u003cp\u003eFully rebuildable for long-term use\u003c\/p\u003e \u003cp\u003eFits ML350, ML550, and other W166 M-Class models\u003c\/p\u003e \u003cp\u003eSolves common error codes: C1525-005, C1511-002, C1516-008\u003c\/p\u003e \u003cp data-sourcepos=\"17:1-17:214\"\u003e\u003ca href=\"https:\/\/www.instagram.com\/functionandform\/\"\u003eFollow us on instagram\u003c\/a\u003e\u003c\/p\u003e \u003cp data-sourcepos=\"17:1-17:214\"\u003e\u003ca href=\"https:\/\/www.f2suspension.com\/\"\u003eCheck out our other products\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003e","brand":"Function \u0026 Form","offers":[{"title":"Default Title","offer_id":42880855146581,"sku":"F2-2626DE0F","price":39330.0,"currency_code":"MXN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/5040\/files\/Function-and-Form-F2-Suspension-Type-4-Inverted-Monotube-Coilovers_7cae12b8-125a-468d-8cb1-a9a4566018f4.jpg?v=1786982632","url":"https:\/\/speedzone-web.com\/en-mx\/products\/mercedes-benz-m-class-w166-2011-type-4","provider":"Speedzone Performance LLC","version":"1.0","type":"link"}
