There are two options for placing your order:

1. (Most affordable) You send in your leaking cylinder, and Top Hydraulics rebuilds it.

  • Top Hydraulics replaces & upgrades ALL seals in your cylinder with our superior proprietary material including rod seals, gland seals, port seals, plug seals and piston seals. Top Hydraulics' u-cup seals have a far more reliable seal and much longer service life.

OR

2. (Fastest) Core Exchange Option where Top Hydraulics ships parts from our inventory first ($155 plus a $200 deposit).

  • Option 2 means that you get a rebuilt & upgraded cylinder from Top Hydraulics' inventory first, then you ship back your original part for credit of your $200 core refund. You get a cylinder that has been rebuilt to outlast and outperform OEM replacements.

This is the main vario roof actuator on the driver side, next to the roll bar. It is highly recommended to upgrade these cylinders in pairs.

Early model years (98 and 99) have curved fittings at the hose ends that attach to the hydraulic pump. Mercedes started using straight fittings in 2000. Both versions are fully interchangeable and equal in value. 

Please note that the hydraulic lines must be attached and intact on the cylinders that you send to us. Top Hydraulics can now replace hydraulic lines, but there would be an additional charge of $100 per line.

Please note that it is highly advisable to upgrade the trunk cylinders and the main lift cylinders in pairs. When considering the labor involved in removing one cylinder compared to a full set of cylinders, it is usually best to have all cylinders upgraded at the same time. The reason is, the majority of the labor involved is in removing access panels, and once the panels are removed, it is comparatively not much more work to remove all cylinders at once. Remember, the rebuild service for all cylinders at once costs about as much as a single replacement cylinder, and you get a much better product... 

Top Hydraulics offers two options for upgrading cylinders for Mercedes convertible tops.

For Rebuilding Your Cylinders:  Send your cylinders to Top Hydraulics first and we will rebuild and upgrade them to better-than-new condition. 

To order with Core Exchange:  Core deposits will be refunded in full if we receive your matching cores within 30 days, the cylinder rods are unscratched, and the hydraulic lines are intact. This option may not always be available, depending on stock. A small "rental charge" may apply if the cores get returned later than 30 days from receipt - we will typically give you a generous grace period.

Seals used by Top Hydraulics, Inc. include Viton™ and Teflon™-hybrid seals, as well as enhanced Polyurethane material, which far exceed the OEM's requirements for rigidity, but provide at least double the service life for your convertible car top actuators, based on scientific test data.

About the port seals: 
At the age of the original parts, it is essential that the port seals (where the hoses go into the cylinder housing) get replaced. Of course, we are replacing them with a far superior version. Replacing the port seals requires some fancy machining and extra parts: 

On the main lift cylinders, we machine out the crimps in the aluminum cylinder housing, create a clear mounting surface and tap holes for clips, then we finally re-fasten the hydraulic lines with laser-cut, stainless steel clips.

In the end, you get parts from us that are far better than new ones inside at a fraction of Mercedes' list price.
