Not satisfied with just picking an off the shelf shock that fits the space,
we worked for a full year computing motion ratios, wheel rates, sprung and
un-sprung weights, critical damping and a massive list of other variables to
design our own proprietary Street, Sport and Race shock & spring combinations
specific to the 65-73 Mustang and other vintage Fords. We do NOT use a standard
'off the shelf shock' that simply fits in the space and 'sort of feels right'.
Each shock and spring package is designed based on the vehicles weight and
Alongside the year of math, shock curves and shock dyno time we drove many, many
street miles and 100's of laps on our favorite racetracks for a real world 'seat
of the pants' validation of each combination from us and a selection of test

The 3 shock valving & spring combinations available for our coil over
We feel that this combination rides as close to a modern production car as you
are likely to get from your classic. That was our goal and we feel we've
met that. In fact even our shock tuning
engineer was blown away at how nice our 1966 Mustang coupe test car drove down a
bumpy, twisting Michigan road! Choose this system if you want a smooth yet
responsive ride from your classic that you can drive for hours and hours without
feeling beaten up. Due to the lighter spring rate used, this is also our
recommended setup for dual purpose street or drag car.
We worked really hard on this package to design it for all those dual purpose
street or open track cars out there. This package gives a smooth, crisp,
controlled ride on the street but can also handle bouncing off the curbs and
slick tires at the road course. Choose this system if you like carving
around bends, on/off ramps and/or open tracking with NO need to switch shocks or
click gimmicky knobs.
For our race setup, the shock gets switched for one with a Schrader valve to
adjust/set nitrogen pressure. With a shock inflator gauge like #LON50473 and a tank of
nitrogen from your local welding supply store, this enables the customer to change gas pressure beneath the dividing
piston. Choose this option for a dedicated track car. Our hired
'butt dyno' driver lapped 3 seconds quicker in his 1965 coupe when compared to
times using his highly modified conventional front suspension setup. The
stop watch doesn't lie. This valving can also be built into a Bilstein
shock without the Schrader valve should you not wish to have the option to tune
gas pressure but still want the race setup.
New! Our new double adjustable shocks are like 3 shocks in 1. Set both adjusters at #1 and you have our Street valving, both at #5 and you have our Sport, both at #10 and you have our Race valving!
All of the shocks used in our coil over system will give many, many years of
service. When the time comes, the shocks are completely rebuildable/serviceable
by us or any worldwide Bilstein rebuilder. You can rest assured that your
investment in this system is one that you can easily maintain and enjoy for many
Below you can see our optional shaft mounted bump stop conversion. This
NASCAR spec. progressive durometer bump stop installs on the shaft of our
Bilstein shock and replaces the stock bump stop. This enables you to
remove the outer spring tower cover and bump stop allowing a slightly lower ride
The stock bump stop is extremely hard and has a tendency to upset the
handling of the car. The progressive nature of this bump stop slows down
the impact when the suspension bottoms out, minimizing the unsettling nature of

Another exciting optional upgrade we offer to our coilover system is these high precision ball joints.
These precision ball joints offer the precision of a spherical bearing with the misalignment range of a ball joint.
Their rugged steel housings will withstand impacts that can destroy other ball joints.
Plus, even if you manage to damage the joint, they are fully rebuildable.
The alloy steel ball studs are process coated for low friction and long wear.
You will feel the difference in smooth travel and easy steering effort.
