New product

Top Hydraulics upgrades the seals in these cylinders with far superior material. It is highly recommended to upgrade the tonneau/case cover cylinders in pairs. Send in your cylinders first, or order from our stock with the core exchange option below.



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, cylinders must be in good condition except for leaking seals.  The core exchange option includes a non-refundable $30 inventory management fee.
