You remove your cylinders you would like to have rebuilt, and send them to us. Core exchange (where we ship from our inventory first) is available only for full sets of eight cylinders, or for the front latch cylinder.

Once we receive your cylinders, the turn around time is 1-3 days for rebuild service and we will ship the cylinders back to you by USPS Priority Mail ($10 within the US, 2-3 days delivery time), or by FedEx Priority Overnight ($40 within the US), or by FedEx International Priority for just $50.

These cylinders typically fail first in the rear of the cylinder, where the mounting pin goes through the housing. The OEM (Original Equipment Manufacturer) cylinders have front and rear caps that are sealed from the cylinder bodies with a seal material that decays over time. Top Hydraulics replaces those seals with a far superior material that is not sensitive to water and is resistant to most additives in hydraulic fluid. Our seals have a larger cross section for a superior static seal. The OEM cylinders rely on a tiny rod seal for the cylinder shaft to slide through.

Top Hydraulics manufactures and installs its own precision CNC machined front caps (glands) in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics' own u-cup seals for a far more reliable seal and much longer service life. In addition, the size and geometry of Top Hydraulics' u-cups is forgiving to tiny scratches and imperfections in the cylinder rods (aka piston rods or shafts), caused during the original manufacture, during removal from the car, during installation into the car, or by impurities in the hydraulic fluid. Top Hydraulics replaces the port seals (where the hydraulic hoses attach) and ships spares with each cylinder, in case your mechanic accidentally pinches an o-ring while installing the hydraulic hose.

Owning and driving a convertible with an automatic top is prestigious, convenient and exciting - let Top Hydraulics help you enjoy your beautiful car even more by making your convertible top system truly better than new!.

Top Hydraulics replaces those seals with a far superior material that is not sensitive to water and is resistant to most additives in hydraulic fluid. Our seals have a larger cross section for a superior static seal. The OEM cylinders rely on a tiny o-ring to energize a very thin, flat rod seal. The o-rings loose elasticity over time, and the OEM rod seals wear out.
