Corvette C6

Rebuild & Upgrade service for Corvette C6 Convertible hydraulic cylinders, lines, and pumps. Core exchange is currently not available for Corvette C6 components. You send us the part(s) you need to have upgraded, and we will turn them around in 1-3 days. Using the best seals available, far exceeding OEM quality.

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.

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!.

Chevy SSR

The Chevy SSR has eight hydraulic cylinders to actuate and lock the cover, and to actuate the top and cover extension: - Two top lift cylinders - Two locking cylinders for the storage (tonneau) cover latches - Two lift cylinders for the storage (tonneau) cover - Two lift cylinders for the storage cover extension lid. (The top latch above the windshield is electric.) The hydraulic cylinders are connected to the hydraulic pump via hydraulic hoses. Top Hydraulics manufactures new hydraulic hoses out of superior material, and Top Hydraulic s can rebuild your SSR folding top hydraulic pump.

Unfortunately, the seals in the hydraulic cylinders deteriorate with time, and the service life of the original seals can be less than ten years in warm climates. This decay is a chemical reaction that gets accelerated by high temperatures or by additives to the hydraulic fluid. Each cylinder has four static seals that seal the front and rear caps and the hydraulic line ports, plus a rod seal that seals the moving metal rod to the cylinder body, plus a piston seal that prevents internal leaks and transfers the hydraulic pressure from the pump into movement of the cylinder's piston. Typically, you will see your hydraulic cylinders leaking first at the bottom, where you wouldn't expect it. The first thought will be that an o-ring on the hydraulic line must be defective. It is actually the first sign that all seals need to be replaced. Seal replacement is absolutely not a DIY job, because the cylinders are crimped together. It requires special machinery to disassemble and reassemble these cylinders, plus all four internal seals have special shapes and sizes. The internal seals are not available to the public. Only the port seals (sealing the hydraulic lines to the cylinder body) are standard o-rings, but they do not normally fail unless they get damaged upon hydraulic line installation.

Top Hydraulics manufactures its own internal seals for your SSR hydraulic cylinders. They are a clear improvement over the original seals both in material and geometry. For example, the tiny flat rod seals get replaced with much larger cup seals, which will stay elastic much longer and are more forgiving towards scratches or impurities on the polished cylinder rods. In the extremely rare cases that a cylinder shaft got rusty or damaged by a tool during a futile DIY repair attempt, Top Hydraulics can replace the shaft with a hardened stainless steel version from its own production (for a surcharge).

You send us the cylinder(s) you need to have upgraded, and we will turn them around in 1-3 days. Using the best seals available, far exceeding OEM quality, and making your old cylinders truly better than new OEM cylinders.
