A high quality 3x2
progressive carburettor
linkage designed for great
looks and a positive action
Use with intake manifolds
that put each carburettor
4-7/8 inches apart. See above
for typical manifold
applications. Note: Intake
shown in photos is for
reference only.
Designed and manufactured
exclusively by Stromberg
carburettor, the TwoStep
linkage range combines clean,
traditional looks with
maximum leverage and huge
versatility. Each kit comes
pre-assembled and installs in
just two simple steps,
without the need for extended
throttle shafts. Our kits are
not a 'one size fits all'
solution. Different intakes
use different carb spacing,
so we modelled every kit in
3D CAD and offer different
kits for specific intakes. If
you're in doubt, simply
measure your manifold spacing
- throttle shaft to throttle
shaft.
Check
out the following features:
- 4-7/8
inches from carb to carb
- Extended throttle shafts
not required
- Fits
Offenhauser 3x2 intakes for
early overhead valve engines,
like Ford Y-block and '49-'61
Cadillac, but check carb
spacing before ordering
- Use two of these kits
with 9261-BB Back-bar for 6x2
Edelbrock X1 Ram intake
- To use with banjo
fittings, add 9086K spacers
- For a chrome direct
linkage at this spacing,
order 9246S and shorten the
rod by 1-1/4 inches.
-
Progressive kits have
opposite threaded rod ends
for easy adjustment. Just
spin the rod to adjust for
the correct lever angles.
- Extended throttle shafts
are not required.
-
Die-cast zinc SuperLink lever
arms. All other parts
stainless steel - even the
rod ends and lock nuts.
- Every kit comes with two
new Stromberg 'Snapback'
throttle return springs,
which wrap around the end of
the throttle shaft. These
chemically blacked, stainless
steel torsion springs snap
the carburettors shut, yet
virtuallydisappear from view.
- TwoStep progressive
systems are designed to
ensure optimum performance
and ensure maximum
versatility. The primary
lever has three mounting
points to change when the
secondary carburettors open,
and you can pull the front
carburettor or push the rear
one open to suit individual
applications. On the top
setting (as supplied), the
linkage will start to open
the secondary (end)
carburettors at around 50%
primary (center) carburettor
throttle rotation. Lower
holes will open the
secondaries sooner.
-
To improve leverage, the
primary (center) arm was kept
as long as possible without
hitting the carburettor
S-jet. It also has a bigger
clamping screw to handle more
linkage torque. The sliding
progressive rod meets the
secondary carb rod at the top
of the lever arm - not part
way down like some systems.
Good leverage is especially
important as 97 multi-carb
systems have strong spring
resistance.
- Special
swivels and bolts were
developed to clamp the rod
ends tight, yet stillallow
the sliding swivel to rotate.
The neat tapered rod stops
have discreet set screw
fixings. And the rounded bolt
has a small blind hole in the
head. Simply insert a small
hex key (like the one you use
for the small rod stop set
screws) to stop the swivels
turning while you tighten the
lock nuts.
-
WARNING! To use this linkage
with banjo fuel fittings (eg.
Stromberg 9082K and 9083K),
you must add our 9086K banjo
fitting spacers. Without
them, the banjo and its fuel
hose will interfere with the
long primary (center) lever
linkage arm causing linkage
binding or sticking, which
could result in uncontrolled
engine speed, property
damage, serious personal
injury or death. Always read
the instructions before
Every
Stromberg TwoStep linkage kit
comes with full instructions,
and further help with
selection, installation and
tuning is available at our
Tech Center.
