Following in the tradition we've set with our first shock dyno, we introduce the Dyno II. With it's polished aluminum and carbon fiber exterior it's obvious we spent time designing this one. But it's not just looks. We've also fully encased the motor and linkage for quiet and safe operation. The Dyno II has what we feel are the necessities for shock building and tuning. We stand behind the dyno with a two year warranty on parts, labor and software. The base system includes the dynamometer, Force vs. Velocity software, temperature control and the Shock Doctor program. A computer system with printer can be supplied at customer request. All data can be stored on your hard drive, or any other means of storage (floppy, Jaz, Zip, CD, Etc.). The program will work with most Windows compatible computers or laptops. Call or email for your free demonstration disc.

Force vs Displacement
One of the new displays.
The continuous velocity
display shows Force vs Displacement at a computer controlled fixed speed.
It displays one cycle worth
of data. readings are taken
every 1/2 of a degree.
Force vs Velocity (POS)
The continuous velocity
display shows Force vs Velocity (POS) at a computer controlled fixed speed. This graph shows one cycle of data.
Force vs Velocity (Neg & Pos)
The continuous velocity
display shows Force vs
Velocity (Neg & Pos) at a computer controlled fixed
speed. This graph shows
one cycle of data.
Force vs Displacement
Overlay of Force vs Displacement of two different shock runs.
Force vs Velocity (POS)
Overlay of Force vs Velocity (POS) of two different shock runs.
Force vs Velocity (Neg & Pos)
Overlay of Force vs Velocity
(Neg & Pos) of two different
shock runs.



• Graphic display
• Compression over rebound or rebound over compression
• 0-12 velocity scale
• Automatic or manual vertical scale
• Grid lines on graph (none, vertical, horizontal,both)
• Total force or damping force only
• Multi shock comparison
• Shock Comparison Graph Display
Overlay up to 10 different shock histories at one time. Multi color display makes it easy to compare. The shock you're currently testing is displayed in blue, every consecutive comparison is shown in green, light blue, red, pink, yellow, gray, dark green, light gray, brown, and on the tenth shock, purple.

• Automatic Shock warm-up feature
• 12 bit A/D accuracy
• The Shock Doctor
Allows you to show the data at even closer detail by isolating a segment of the graph and review it at close up range, then print out the results in color or black & white.
Grid style, select none or horizontal.
Force calculation, select dampening only or total force.
Graph display force, select compression over rebound or rebound over compression.
Temp, automatically reads temperature of shock.
Vertical scale, choose automatic which sets the grid to whatever the shock tests at, or manual which allows ...you to set the grid to figures you select. Useful for shock comparisons.
Velocity, select speed at 1/10" increments.
Zoom X, lets you view graph at six different settings, giving you an upclose and personal look at valve ...openings and closings, valve bleed and peaked force. Also shows lag time from rebound to compression.

• Temperature Monitoring System
•Shock performance can vary dramatically at different temperatures. These temperature performance changes ..can directly influence the handling characteristics of your car. With the temperature monitoring system, you ..can determine how your shock will perform under various temperatures. You can automatically warm the ..shock to a temperature you select and read the temperature at any time!
• Computer Compatibility
•Use with your
IBM compatible computer or order an optional computer / laptop with color printer. The software ..is compatible to run in Windows 95, 98, 2000, ME, XP.
