Pair of Z4 Hinge Cylinders - BMW Z4 (E85) 2002-2008

$545.00

There are two options for placing your order:

1. (Most affordable) You send in your leaking pair of Hinge Cylinders, and Top Hydraulics rebuilds them.

  • 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 cylinders that have been rebuilt to outlast and outperform OEM replacements.

OR

2. (Fastest) Core Exchange Option where Top Hydraulics ships the part from our inventory first ($695 plus a $400 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 $400 core refund. You get a cylinder that has been rebuilt to outlast and outperform OEM replacements.
  • The price listed is per pair.

The core exchange option is offered only in the US and Canada.

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. Top Hydraulics' rebuilds make your original hinges much better than brand new ones inside, 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 currently uses FedEx 2-Day Service as the default carrier for domestic shipments. If shipping over the weekend, then we may elect to use USPS Priority Mail only if we believe it is the better choice for you, i.e., if we believe you will get the parts faster this way. 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, excessive corrosion, 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...
