Rear Lock Cylinder

This cylinder is located in the rear latch, pulling down the rear of the soft top. It is highly recommended to upgrade these actuators in pairs.

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

For Rebuilding The Cylinders That You Send In:  We gladly accept the cylinders in their locks/latches at no extra charge -- you save the extra labor and we have all the assurance that the cylinders do not accidentally get scratched upon removal from the locks. Once we receive your cylinders, the turn around time is approximately one week for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).

To order with Core Exchange: For locking cylinders, we will usually ship a custom made loaner wrench for easy removal of the cylinder from the lock. Core deposits will be refunded in full if we receive your matching cores within 90 days, and the cylinder rods are unscratched. A small "rental charge" may apply if the cores get returned later than 90 days from receipt, but we are usually extending the return period within reason without such a rental charge.

Metal parts in your hydraulic cylinders do not get damaged during normal operation. Sealing surfaces (for example the polished, chromed cylinder shafts sliding through the rod seals) can easily get scratched beyond repair by tools - especially during DIY repair attempts. Top Hydraulics can replace any damaged metal parts but has to charge extra for that service.

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 more than double the service life for your convertible car top actuators, based on scientific test data. Making your roadster/cabriolet hydraulics better than new!
