Performance

Pro-Kit is Eibach's progressive-rate lowering spring set. It drops the car by 40–45 mm at the front and 30–35 mm at the rear on the standard dampers, so the centre of gravity falls and body roll through a corner is reduced without turning the ride harsh. The progressive rate stays compliant over small bumps and firms up as the spring compresses, which is what keeps the car usable on poor roads while still feeling tied down at speed.

Fitment

Fits Mercedes-Benz S-Class (W126), 10/1979–06/1991, RWD; and Mercedes-Benz S-Class Coupe (C126), 10/1981–07/1985 — see the full list below. Verify fitment using the vehicle compatibility checker above.

What's Included

One complete Eibach Pro-Kit spring set for this vehicle — springs for both axles, supplied together as a matched front-and-rear set (F2506001 · F2506002). Dampers, top mounts, bump stops and fixings are re-used from the vehicle unless the specification table above lists them.

Warranty

Backed by Eibach's manufacturer warranty against defects in materials and workmanship. Cover assumes the set is fitted complete and as supplied, by a workshop with the correct spring tooling. Mixing these parts with springs or dampers from another set puts the load outside what this set was tuned for and is not covered. As an official reseller in the EU, Suspengo also handles your statutory conformity rights on this purchase — contact us first and we deal with the manufacturer.

Notes

• If not separately named, for vehicles with OE-lowered suspension, the dimension of lowering is reduced by the dimension of lowering carried out by manufacturer. If not separately named, vehicles with OE-lifted suspension (e.g. Offroad-Package, Crossover) are excluded from use of our products.
• The specifications indicated in the Components Certificate are for the classification of the item / vehicle. Please check the type Components Certificate number of your car and compare with the Components Certificate. (Letter "K" in your vehicle registration certificate or to find at the type plate of your car!)
• Please verify before fitting by means of the Components Certificate whether the delivered items (please see marking) are approved for your vehicle (please see area of use).You can find the current Components Certificate on www.eibach.de
• In case of non-conformance the items must not be fitted – please refer to your dealer.
• Mounting - we recommend to have our spring system installed by a qualified workshop only, that has skilled personnel and the required special tools available. - If the installation deviates from the workshop manual, Eibach-Eibach instructions are available online.
• Mounting position - you can "read" the mounting position of the springs from the imprint - have them installed just the way you read the imprint.
• Wheel adjustment - after completion of the spring/suspension installation, checking the wheel adjustment is required.
• Shock absorbers - if the standard shock absorbers are not fully operative anymore and their efficiency has worn off considerably, we strongly recommend to replace those by new standard shock absorbers or by sports shock absorbers, if using lowering springs. This already can be necessary from 40.000 kilometers OE-damper-milage.
• The installation of Sport-Shock Absobers is recommended with Sportline springs. As example Bilstein B8
• Here all wheel/tyre-combinations are possible, which are released by the wheel type testing institution. The instructions in the wheel Components Certificate have to be adhered to, except for: OE suspension is required.
• Depending on engine, gearbox/transmission, equipment and vehicle tolerances lowering may differ from the values given. The dimension of lowering is reduced by the dimension of lowering carried out by manufacturer.
• The applicability of our products deals with standard cars. In any case of reconstruction (even with OE-accessory-parts), as the installation of an accessory-brake-system (e.g. ceramic-brakes), sport-suspension, LPG-(liquefied petroleum gas)-system for example, the usage of our products may be excluded. The stated measurements are referring to new standard cars. Measuring points: vertical distance from the middle of the wheel hub to the bottom edge of the mud wing. Generally the stated measurements are nominal values, which can vary depending on every car.
• If your vehicle has serial electronic damper control this will not be available anymore while using the B12- or Pro-Street-S-suspension kit. You will see a trouble code. This can be re-programed by an official garage/dealership. If available for your vehicle, we recommend to use Pro-Tronic to avoid the trouble code.
• The spring plates installed by the manufacturer are available at DB specialist workshops in sizes 8-23 mm. This allows to vary the lowering indicated here.
• Without levelling control.
• Except vehicels with 4WD.
• for vehicles without AMG-suspension
