Cadillac

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.

Chevrolet Convertible Top Hydraulic Cylinder Rebuild/Upgrade Service

Rebuild & Upgrade service for convertible Chevrolet models.  Select your vehicle below.

Chrysler

Convertible hydraulics rebuild & upgrade service (using best seals available) for Chrysler Crossfire Cabriolets and Chrysler PT Cruiser.

Chrysler Crossfire Convertible Model Years 2003-2007 use six hydraulic top cylinders. There are two locking cylinders, two for the bow tension (moving the rear window up and down), and two main lift cylinders. Unfortunately, the seal material used in the OEM cylinders is particularly prone to chemical decay in warm climates, and we highly recommend to upgrade all cylinders at the same time. At the very least, cylinders should be upgraded in pairs. On the bow tension and main lift cylinders, Top Hydraulics actually replaces a total of six seals. Top Hydraulics' proprietary seals are far superior to the original seals used both in choice of material and in their geometry. This makes your used cylinders actually better than new ones, with a much increased service life. You send in the cylinders that you want to have upgraded, and Top Hydraulics will turn them around within 1-3 days.

Chrysler PT Cruiser Convertible Model Years 2006-2008 use two hydraulic lift cylinders. Top Hydraulics offers a Core Exchange option for PT Cruiser hydraulic cylinders, where we can ship cylinders from our stock first.

Jaguar Convertible Top Hydraulic System Rebuild/Upgrade Service

Jaguar

CYLINDER UPGRADES -- NEW, UPGRADED HOSES -- PUMP UPGRADES

Are you a victim of the infamous "green shower" from above the windshield? Are Jaguar hoses on back order again (guess why - the original ones are all failing...)?

Let Top Hydraulics supply you with new, better hoses at a lower price, and let us upgrade your old cylinders so that they will be better than brand new ones - no kidding!

We currently upgrade Jaguar convertible hydraulic cylinders for the 1996-2006 XK8/XKR models with their high-pressure systems containing two top lift cylinders and one latch cylinder, plus six hydraulic hoses.

The rod seals used for the cylinder rebuild/upgrade are far superior to the original ones in geometry, size and material choice.

Top Hydraulics does not only replace the original seals, but precision-manufactures metal parts that accommodate our larger and much longer lasting seals. That is why our rebuilds are actually upgrades - we make your old cylinders better than new!

Top Hydraulics' Kevlar-reinforced hoses have a burst pressure rating of 23,200 psi, and are clearly the best option available to Jaguar owners. You remove your cylinders that you would like to have rebuilt, and send them to us. Core Exchange is currently NOT available for Jaguar cylinders.

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

We ship internationally on a daily basis.

Please note that in the unlikely event the black/brass colored main lift cylinders should have rust or serious mechanical damage on the chromed shafts, a proper rebuild is currently not possible.

Pontiac

Pontiac G6 Folding Top Drive Cylinders and Pump

The G6 has seven hydraulic cylinders that activate and latch/unlatch the folding top, powered by one hydraulic pump. The hydraulic cylinders typically fail first in the rear (bottom) of the cylinder. 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 o-ring to energize a very thin, flat rod seal. The o-rings loose elasticity over time, and the OEM rod seals wear out.

Top Hydraulics manufactures and installs its own precision CNC machined front caps 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.
