There are two options for placing your order:
1. (Most affordable) You send in your leaking single Hinge Cylinder, and Top Hydraulics rebuilds it.
- Top Hydraulics replaces & upgrades the seals in your cylinder with our superior proprietary material. Top Hydraulics' u-cup seals have a far more reliable seal and much longer service life. You get back a cylinder that has been rebuilt to outlast and outperform OEM replacements.
OR
2. (Fastest) Core Exchange Option where Top Hydraulics ships the part from our inventory first ($355 plus a $250 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 $250 core refund. You get a cylinder that has been rebuilt to outlast and outperform OEM replacements.
The core exchange option is available only within the US and Canada.

Price listed is for rebuild/upgrade service for an individual hydraulic hinge cylinder.
It is highly recommended to upgrade them in pairs. These hydraulic cylinders always fail almost simultaneously.
To order a pair of hinges instead, click here.
Note that there is a significant amount of labor involved in removing and replacing (R&R) the hinges on a Z4 top, and that both hinges always fail (leak) at almost the same time. It is close to the same amount of labor to R&R both hinges compared to R&R of a single hinge. This makes it highly inadvisable to deal with only one hinge at a time. To order a pair of hinges instead, click here. Top Hydraulics' rebuilds make your original hinges much better than brand new ones, on account of the far superior seals used. Usable service life expectancy of Top Hydraulics' rebuilt hinges should be over 30 years under normal circumstances, with a 3-year warranty.
For regular rebuild service, where you send us your hinges first, then we rebuild them, then we ship them back. Top Hydraulics may elect to use FedEx Express Saver instead if shipping to a business address. Shipping inside the US is only $15, and international shipping by FedEx International Priority is only $85 to most countries. The core exchange option is available only within the US and Canada.
If you are in a hurry: domestic FedEx Priority Overnight shipping from Top Hydraulics via FedEx is only $55.

These hinges are actually very well made; only the OEM seals decay over time. Top Hydraulics replaces the leaking seals with material far superior to OEM quality.
For core exchange orders, where Top Hydraulics ships parts from its inventory first, then you return your old parts. the deposit is fully refundable if Top Hydraulics receives matching, rebuildable cores within a reasonable time frame. Core exchange is offered only in pairs, and core exchange cylinders ship exactly as pictured. In particular, this means they ship with the arms attached, but without the detachable mounting bracket (mounting bracket not shown in the photos - it is used to secure the interior trim of the car). Top Hydraulics recommends leaving the arms on the hinges, or it will be cumbersome to get the gear timing correct afterwards.
The rebuilt & upgraded cylinders (hinges) feature new and greatly improved rod seals, piston seals, gland seals, and port seals (where the hydraulic lines go into the cylinder). The service life should be at least 3 times as long as with the original seals, under similar circumstances.
In rare cases of excessive damage from previous DIY repair attempts or from someone forcing the top manually and bulging the cylinder housings that way, Top Hydraulics may refuse to work on your parts and refund your payment.
For shipping your hinges to us within the US, USPS Priority Mail Medium Flat Rate Boxes are a good choice. Be sure to package well, so that nothing gets lost in transit...

FedEx International Priority
For Customs clearance, you must declare a value on the package you are sending us. Please note: parcels with a declared value under US$750 enter the US without incurring taxes, duties or clearance fees. Considering that you are sending us broken parts for repair, it is most reasonable to declare a value under US$750. You can insure your parcel only up to the amount that has been declared as the value for customs, so your best insurance is good packaging. It is extremely rare that parts get lost on the way to us.
Please be sure to drain or cycle all fluid out of your parts, then wrap them in plastic, so that the parcel does not get soaked in oil. It is generally a good practice to double box pumps or sets of cylinders because heavy parcels take quite a beating in international transit unless you are using a premium carrier such as FedEx. Clearly, you don't want to just stick a part into a cardboard envelope without any further protection or buffering. Buffer your parcel well inside so that parts don't rattle around or the parcel gets crushed from others on top of it. Ideally, tape all around all surfaces of the parcel, which generally provides excellent protection against losing components that are trying to escape through small holes in the cardboard.
We use FedEx International Priority for almost all outbound international shipments, as they tend to offer the fastest and most secure service. Due to our shipping volumes, our rates for return shipping your parts via FedEx International Priority are typically equal to or cheaper than Postal Service. We cannot offer shipping labels for your shipment from you to us - you will have to shop around for the best option to ship your parts to us.
In the rare event that you feel you have to declare a value over US$750 on your parcel shipping to us, please understand that we will need to be reimbursed for any importation fees or duties incurred. You agree to this by accepting our terms and conditions when you place your order. On high value parcels, we are typically charged an Entry Prep Fee (currently about $25) plus 2.5% tax on the declared value of the package, there are oftentimes delays in customs, and it can take a while for us to receive the actual customs invoice.
Depending on the parts you are sending us, your customs declaration might say "hydraulic cylinder for repair" or "hydraulic pump" for repair. Please note that DHL does not like to carry hydraulic parts or used car parts in some countries. If your carrier asks for the "harmonized code or tariff" of the parts you are shipping, those are 841221 for linear actuators (cylinders) and 841360 for pumps.
At Top Hydraulics, we pride ourselves on providing new and remanufactured parts with unmatched quality and longevity.
It is very rare that our parts fail. Obviously, we are only human and we could have made a mistake or one of our components might indeed have had a hidden defect. Please contact us first when you suspect that you have a warranty case, so that we can try to help right away. It could be that the failure you are experiencing is caused by a different component or that the installation was not quite proper, so we like to be in touch first to go over the situation with you.
Unless stated otherwise, there is a 3 year warranty on all new and remanufactured parts provided by Top Hydraulics. This warranty is transferable. All parts manufactured or rebuilt by Top Hydraulics have unique markings, so there is no additional paperwork needed to transfer a warranty. The warranty does not cover labor, direct or consequential damages. The warranty is void when the parts have been abused or have been installed incorrectly, or when brake fluid or stop-leak additives have contaminated your hydraulic system..
You will have to send your failed part(s) back to Top Hydraulics for a warranty evaluation. In the extremely rare case of failure on rebuilds or new parts shipped or provided by Top Hydraulics, Top Hydraulics' warranty covers only parts and is limited to rebuilding the products previously shipped by Top Hydraulics, or replacing them, or refunding the rebuild fee at Top Hydraulics' discretion. If the failure was our fault, then we will refund reasonable shipping costs, as well.
