Hydraulic cylinder upgrades - OEM used inferior seals on all six cylinders
Wow, three Canadians already in the same thread, who have used our services - thank you for sharing!
Seb_323ci_2000, you did not waste your money on having your main drive cylinders (aka main lift cylinders) upgraded by us - they would have failed sooner or later, and now you should never have to worry about them again.
The OEM cylinders have cup seals made of Polyurethane in them, which have a fairly limited service life. Top Hydraulics replaces them with cup seals made of a far superior material, which should last several times as long as the original seals under the same conditions. That means, we make your old, leaking cylinders better than new ones for a fraction of what you would pay your dealer.
gbakerkingston, you mentioned it taking three weeks to get the cylinders back. I think over 90% of that was shipping time. We now average about a one-day turn around time on BMW E46 cylinders, although we wouldn't promise it. ;-)
