Rebuild service for Right Trunk Lid Cylinder Mercedes R170 SLK-Class

New product

Mercedes part number A 170 800 02 72.

$95 for Standard Rebuild Service, where you send in your cylinder first to be rebuilt.

Optional core exchange (where we ship a part first from our inventory) is $135 plus $120 deposit.

Top Hydraulics replaces and upgrades all port seals (where the hoses go in) and the cup-shaped rod seal. Top Hydraulics' rebuilt cylinders are far superior on the inside to new parts from the dealer, at a small fraction of Mercedes' list price!



For optional core exchange, select YES in the drop down menu above.

Core exchange means that you get rebuilt parts from Top Hydraulics' inventory first, and then you send back your original parts for a refund of your core deposit of $120. For a full core refund, parts must be in good condition except for leaking seals.


R170 SLK-Class | Years: 1998-2003/2004


We have two service levels: rebuilding the cylinder(s) you send in, or sending you a complete set from our stock with core exchange (inventory surcharge, plus a refundable core deposit apply).

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. If you are using the core exchange option and you have a preference for the fitting version that we ship to you, please indicate your preference during checkout.

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 $50 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:  Once we receive your cylinders, the turn around time is up to two business days for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).

For Up-front Shipping with Core Exchange:  Core deposits will be refunded in full if we receive your matching cores within 60 days, the cylinder rods are unscratched, and the hydraulic lines are intact. 

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 - you won't find this quality elsewhere.

On the trunk lid cylinders, we machine out the crimps in the steel tubes that the hoses go into, cut a thread around the steel ports, then re-fasten the hoses with CNC-machined sleeves.

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