You remove your cylinders you would like to have rebuilt, and send them to us.
Core Exchange is currently available only for 1st generation Saab cylinders.
Important: deep scratches or rust spots on the polished cylinder shafts require us to replace the cylinder shafts, which we manufacture out of hardened, stainless steel. There is a surcharge for shaft replacement, if needed. If we can polish out existing damage, then there is no surcharge.
Once we receive your cylinders, the turn around time for Saab cylinders is 1-3 days for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).
Top Hydraulics also manufactures new hydraulic hoses (also called lines or pipes) for all Saab 9-3 models. All hoses for 1st Generation 9-3s are listed on the website - please contact us for specific 2nd Generation hoses that you do not find listed.

Rebuilding and upgrading hydraulic system components for your First Generation Saab 9-3 or Saab 9-3 Viggen Convertible - Top Hydraulics' quality is unmatched!
We upgrade your cylinder(s) by replacing the tiny OEM rod seal with a much larger one made of superior materials, and adding custom caps made of CNC machined stainless steel to accommodate these superior seals. Our seals are not sensitive to water and are resistant to most additives in hydraulic fluid. This results in a much longer service life than the standard OEM cylinders for a fraction of the price.
Our Core Exchange option makes this as easy as buying a new cylinder - you only have to ship back your old cylinder(s) afterwards for core credit.
Top Hydraulics also rebuilds and upgrades convertible hydraulic pumps, as well as manufacturing our own upgraded hydraulic lines.
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' standard warranty is 3 years on rebuilds/upgrades of convertible top cylinders and hydraulic pumps, and on new hydraulic hoses.

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.
