Special option: Core exchange. Price includes $900 deposit. This means you pay $1300 plus $900 deposit plus shipping, then you get a rebuilt & upgraded set of cylinders from Top Hydraulics' inventory first, then you ship back your original set to recover your deposit. The deposit gets refunded in full if the cores do not have serious damage to the metal parts or missing components.
No sales tax for orders in the USA
We provide world class technical support
3-year standard warranty (should last decades)
The core deposit ($900 out of the $2200 that you are paying) gets refunded in full if the matching set of cores (your original cylinders with latches) is returned within 90 days and there is no serious damage to the metal parts or there are components missing.
Seals inside the cylinders get upgraded, and design flaws get rectified. Cylinders rebuilt by Top Hydraulics perform better than brand new ones, and Top Hydraulics' seals will far outlast those in brand new OEM cylinders. The set we are shipping to you may not be perfect cosmetically, because it has been used before. We do our best to clean up or polish out external blemishes, but what really matters is what's inside the cylinders.
Set of 7 upgraded cylinders, with the best seals available. All OEM cylinders will eventually fail, accelerated by heat and impurities or water in the hydraulic fluid - Top Hydraulics replaces the chemically decaying seals with far superior material.
The full set consists of two main drive cylinders (mounted in the soft top frame), two bow tension cylinders (also mounted in the soft top frame), one tonneau cover lift cylinder, and two locking or latch cylinders (locking down the rear window and the storage cover).
