XYZ Racing Gravel Rally Coilovers — Mercedes-Benz S CLASS W221 (NON ABC hydraulic or 4WD) 2006-2013

The W221 S-Class is a two-tonne luxury saloon built around isolation, not feedback, and that is exactly the problem this kit sets out to solve. Strip away the soft factory damping on a non-ABC, rear-drive 2006-2013 car and the chassis underneath is genuinely capable – long wheelbase, wide track, multi-link rear – it has just never been allowed to do anything with itself.

The XYZ Racing Gravel Rally coilover is the loose-surface specification in the XYZ range, set up for compliance over rough ground rather than circuit flatness. On a W221 used for unsealed roads, fast B-road work or simply an owner who has had enough of the OEM air-replacement bills, it gives you a steel-sprung, fully serviceable platform with the travel to actually use the chassis.

What this coilover does for your 2006-2013 Mercedes Benz S Class W221 (NON ABC hydraulic or 4WD)

The first thing you feel is the body settling. The W221 stops floating on its springs mid-corner and starts taking a set, which means the steering rack finally has something to report back to you. Damping is adjustable so you can run the car softer for poor surfaces and firmer for motorway composure without swapping hardware. Ride height comes down by a measured amount rather than the air-suspension lottery of "wherever the struts decide today", and because the kit is monotube with separate spring and damper, fitment-specific spring rates do the heavy lifting while the dampers stay within their working window. For owners walking away from a failed ABC or air system, the practical benefit is a fixed-cost, rebuildable replacement that does not hold the car hostage to one specific OEM part number.

About the Gravel Rally coilover

The Gravel Rally sits in the XYZ Racing range as the long-travel, rough-surface specification. Construction is monotube with the larger-diameter piston and oil volume needed to keep damping consistent when the suspension is genuinely working – repeat compression cycles on broken tarmac or unsealed roads heat dampers quickly, and undersized units fade. Spring rates are matched to the chassis weight and bias rather than picked from a generic chart, which matters on a W221 because front-end mass is significant and the rear multi-link is unusually compliant for the segment. Damping is adjustable across a wide range so the car can be set up softer for the surface it is actually being driven on, and the kit is fully rebuildable – seals, oil and valving are serviceable rather than sealed-for-life.

Fitment for the Mercedes Benz S CLASS W221 (NON ABC hydraulic or 4WD) (2006-2013)

This kit fits W221-chassis S-Class models built between 2006 and 2013, specifically cars NOT fitted with the ABC active hydraulic suspension and NOT the 4MATIC all-wheel-drive variants. If your car has Airmatic or rear-drive conventional suspension you are in the right place; ABC and 4MATIC cars use entirely different strut and subframe hardware and need a different part.
