This version is listed for AWD models.\u003c\/p\u003e\n\u003ch3\u003e2007-2013 Mercedes-Benz S-Class setup details\u003c\/h3\u003e\u003cp\u003eFront and rear are both true coilovers, which keeps ride height adjustment simple and precise at each corner. Damper bodies are 52mm front and 50mm rear. It comes with 14 kg\/mm (about 784 lb\/in) springs up front and 10 kg\/mm (about 560 lb\/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with rubber bushings. At the rear, the mounts are aluminum with rubber bushings.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMonotube dampers, which shed heat well and hold their damping under hard use\u003c\/li\u003e\n\u003cli\u003e32-level damping adjustment, rebound and compression combined on one adjuster\u003c\/li\u003e\n\u003cli\u003eRide height lowers roughly 1 to 2.5 inches below stock (SF Racing's figure) without giving up suspension travel\u003c\/li\u003e\n\u003cli\u003eSeparate lower-mount (length) adjustment, so height changes don't preload the spring\u003c\/li\u003e\n\u003cli\u003eAnodized T6-6061 aluminum top mounts, spring perches and collars for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eZinc-plated shock bodies for rust protection\u003c\/li\u003e\n\u003cli\u003eSAE9254 cold-wound springs\u003c\/li\u003e\n\u003cli\u003eNOK seals and Italian IP damping oil\u003c\/li\u003e\n\u003cli\u003eBuilt-in dust boots and bump stops\u003c\/li\u003e\n\u003cli\u003eBolt-on install with no modifications, unless the notes below say otherwise\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho it suits\u003c\/h3\u003e\u003cp\u003eIdeal for street cars that need a sensible drop and some tuning range, without going to track-level stiffness.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSF-MB14-07-SP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2007-2013 Mercedes-Benz S-Class\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eW221\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrivetrain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAWD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper model\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSport Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamping\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1-Way: Rebound and Compression\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper size (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e52mm diameter \/ 50mm diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpring rate (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14 kg\/mm \/ 10 kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDesign (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover \/ True Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (front)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum with Rubber Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum with Rubber Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"SPRINGRATES®","offers":[{"title":"Front: 14K \/ Rear: 10K","offer_id":67656368718125,"sku":"SF-MB14-07-SP","price":1095.0,"currency_code":"USD","in_stock":true},{"title":"Front: 16K \/ Rear: 10K","offer_id":67656368750893,"sku":"SF-MB14-07-SP","price":1095.0,"currency_code":"USD","in_stock":true},{"title":"Front: 18K \/ Rear: 10K","offer_id":67656368783661,"sku":"SF-MB14-07-SP","price":1095.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/8295\/1469\/files\/sf-racing-sport-coilovers-for-2007-2013-mercedes-benz-s-class-awd-w221-1194288704.jpg?v=1792170539","url":"https:\/\/lowerhq.com\/products\/sf-racing-sport-coilovers-for-2007-2013-mercedes-benz-s-class-awd-w221","provider":"LowerHQ","version":"1.0","type":"link"}
