Frame Top Seal Main Cylinder - Ferrari F430 Spider


There are two options for placing your order:

1. (Most affordable) You send in your leaking Frame Top Seal Main Cylinder, and Top Hydraulics rebuilds it.

  • Top Hydraulics replaces & upgrades ALL seals in your cylinder with our superior proprietary material including rod seals, gland seals, port seals, plug seals and piston seals. Top Hydraulics also manufactures and installs our own precision CNC machined front caps in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics' u-cup seals for a far more reliable seal and much longer service life.


2. (Fastest) Core Exchange Option where Top Hydraulics ships the part from our inventory first ($260 plus a $200 deposit).

  • Option 2 means that you get a rebuilt & upgraded cylinder from Top Hydraulics' inventory first, then you ship back your original part for credit of your $200 core refund. You get a cylinder that has been rebuilt to outlast and outperform OEM replacements.

Top Seal Main Cylinder Rebuild/Upgrade Service

P/N: 66454700

Model year '04-'09 F430's have seven hydraulic cylinders for soft top actualtion and latching. Top Hydraulics upgrades the internal seals with far superior material, making your cylinders better than brand new ones.

Five of the cylinders have the hydraulic lines permanently attached, and they need to be sent in with the lines attached. If you have a cylinder with a cut hydraulic hose, then Top Hydraulics can replace the hose.

Two of the cylinders have removable lines (the Secondary Frame Top Seal Cylinders high up in the frame). Remove the clamps and send in these cylinders without the lines. Top Hydraulics will also replace the port seals (where the lines go in) on these cylinders p/n 66454000 and 66454100.

Please note that most cylinders fail in pairs, and that all seven cylinders will usually fail in a time frame of some 20% of the age of the first cylinder failing. That means, for example: if the first cylinder fails after ten years, then you are very likely to find the rest failing within some two years.
