UPPER
PIVOT TOP LIFT CYLINDERS
 During
the early 60’s all of The Big Three car makers switched to a
cylinder design with the pivot point at the top of the
cylinder case, allowing the lower part of the cylinder to
rotate fore and aft as the top traveled (a design which is
still employed today). From 1970 on, these cylinders were
constructed partly of plastic, Making it a nonrebuildable,
throwaway part. Convertible Service employs the all metal
construction design of the 60’s and manufactures upper
pivot lift cylinders to fit all convertibles from the 60’s
right up to the present time GM, Ford, Chrysler, AMC and even
Saab, Toyota, Renault & Infiniti M30 convertibles! On other
reproduction top cylinders, the cylinder case is made by
crimping two pieces of aluminum together. At Convertible
Service the cylinders are manufactured according to the
original design by forming an all metal, one piece
case. This process eliminates the possibility of leaks from
the lower part of the cylinder (which is a common problem with
the crimped-together type). The result is …. A more reliable
cylinder. On other reproduction top pivot cylinders the ports
which receive the hydraulic hoses from the pump/motor are made
by screwing in pre-fab external brass fittings which protrude
as much as ¾’s of an inch further than the originals and
create clearance problems when you try to mount them in the
car. Our cylinder castings are formed with the port built into
the castings. They fit right into the car, just like the
originals did!
LOWER
PIVOT TOP LIFT CYLINDERS
From the late 40’s to the early
60’s, top cylinders had their pivot point at the bottom of the
cylinder case. Convertible Service has designed cylinders to
fit the many different configurations of lower castings, port
sizes, stroke dimensions and rod ends (threaded end or forged
eyelet) for the different years and models. We take great
pride in manufacturing quality top cylinders which will fit
your convertible just like the original
.

REPLACE BOTH TOP
CYLINDERS!
Based on ours years of experience and response
from our customers, we recommend replacing both cylinders over
just replacing the one that’s obviously bad.
1. A common reason for replacing a cylinder is that it is
leaking fluid. If only one new cylinder is installed, the
remaining old cylinder, being suddenly required to operate in
a tight, leak-free system under factory pressure, will
frequently begin to leak, too.
2. Teaming a new cylinder with an old one can also cause
unequal lifting force applied to the left and right sides of
the folding top frame, which could, in time, distort the
folding frame or cause the pivot points to wear unevenly.
3. Some older factory top cylinders were designed with a
longer stroke than necessary, so that same cylinder would fit
in several different size cars. If the operator leaves his
finger on the top switch after the top is all the way up, the
hydraulic system is pushing against a dead stop, which can
cause the cylinder rods to bend permanently. For these models,
Convertible Service has designed shorter cylinders which will
push the top all the way up, but no further. Naturally, it is
not a good idea to match new correct size cylinder with and
old one that is too long.
Convertible Service will gladly sell you as many or as few top
cylinders as you want. But for the above reasons, we recommend
that cylinders be replaced in pairs
