You send in your cylinders first; we will upgrade them to better than new condition. Optional core exchange has an inventory management surcharge, plus a $600 deposit.

Includes two main drive cylinders, two bow tension cylinders, and two tonneau cover cylinders.



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 $600. For a full core refund, cylinders must be in good condition except for leaking seals.

Cylinder rebuild & Upgrade service


Please see removal instructions for all cylinders and the most frequently failing hydraulic lines in our DIY section:


The E46 chassis has six cylinders, consisting of two main lift cylinders, two bow tension cylinders, and two case cover cylinders. Turn around 1-3 business days. Hydraulic lines on some cylinders do not have quick disconnects and must remain attached (tonneau cover cylinders and right bow tension cylinder).

Main lift cylinders: p/n 54347025593 (left and right)

Bow Tension Cylinders: p/n 54347025599 (left side) and 54347025600 (right side)

Tonneau Cover Cylinders: p/n 54348236956 (right side) and 54348243269 (left side)

Top Hydraulics return ships by USPS Priority Mail (inside the US; shipping $10 per order) or USPS Express Mail internationally.


The fine print: In the extremely rare case that your chromed cylinder shafts are rusty or deeply scratched, then there may be a surcharge for shaft replacement.
