Amici - Has anyone had any experience these adjustable lever shocks?
Thanks.

Barry,
I attached a picture of the shocks. Only the knob on the
valve has changed. Peter
Thank you for asking about our adjustable Armstrong shocks.
Having been in the remanufacturing business of Armstrong lever
shocks for many, many years, we have had the opportunity to rebuild a few of
the original Armstrong "Adjustable 22" externally adjustable shocks. You can
find examples of these in some of the original special tuning parts manuals.
Armstrong had different castings made for some of these models, but did not
make them available for all of their various models of shocks. Because the
body is somewhat larger and had a large adjusting knob, not all cars could
be fitted with the "Adjustable 22" units.
We have been able to use their same principles and apply them to a
wider variety of lever shocks by employing an external and remotely
mountable valve alleviating the need for new castings and fitment
constraints.. The way the Adjustable 22's and our shocks work is by
utilizing an extremely stiff modified main original "co-axial"
valve assembly in the usual position, and providing a bypass circuit with a
variable needle valve that allows adjustment of the volume of oil that
passes through the co-axial main valve. (The "22" meant that Armstrong had
22 steps of adjustment.) Our valve is variable without steps, and can allow
the shock to be locked solid without moving, to full, undampened movement.
By machining the co-axial valve and replacing the springs with our custom
made ones we succeed in providing a damping rate equivalent to full
competition at 1-1/2 turns open of a potential 5 turns.
The valve is of brass body full flow stainless steel needle
construction. Connections between shock and valve are similar to brake
hydraulic equipment. We've been able to test fit these on all of the models
we offer to ensure accessibility and roadworthiness.
Historically, shocks become less effective as the oil heats.
Our experience has been at about 20 - 25 minutes of track work, the shocks
lose their dampening. After several attempts, we are now using Redline's
suspension oils, and have been very pleased with the performance, especially
in this application.
The modifications of the adjustable shocks are performed on our
highly regarded remanufactured units. We install sleeve bearings in the
bodies, install stainless shaft sleeves, and install radial lip oil seals.
Pistons and bodies are selected for their proven reliability using the best
combinations.
Each order is custom made so that we can consider your intended
use, as well as any additional equipment you may have that would affect the
mounting of the valve. We also like to know if the ride height is
significantly changed as we can ensure the pistons are working in their
mid-range most of the time.
Pricing
Rears are $149.00 each
Usual core charge deposits of $30.00 apply.
Please let me know if you have any questions. We are always open to
suggestions.
Thanks again.
