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.
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.
