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.

Top Hydraulics actually replaces all seals in these cylinders, including the port 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.

Rebuild/Upgrade Service for Chrysler Crossfire Roadster Hydraulic Cylinders

Chrysler Crossfire

The OEM cylinders will all eventually fail, accelerated by heat and impurities or water in the hydraulic fluid - Top Hydraulics replaces all seals with far superior material. Send us your cylinders, and we will rebuild them and ship them back to you.

These cylinders typically fail first in the rear 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.

If your convertible top is moving slowly or not at all, you likely have one or both of the hydraulic cylinders leaking, which emptied out the pump's reservoir. This is normal for a convertible of this age, as the seals in the hydraulic cylinders are decaying. The seals typically decay first on the bottom of the cylinders, where you would least expect it.

Top Hydraulics replaces and upgrades all seven seals per cylinder, with an expected service life of several decades! The PT Cruiser convertible has two lift cylinders for the convertible top. Top Hydraulics' seal material is far superior to the OEM's.
