A high quality 3x2
progressive carburettor
linkage designed for great
looks and a positive action
Use with intake manifolds
that put each carburettor
5-1/2 inches apart. See above
for typical manifold
applications.
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:
-
5-1/2 inches from carb to
carb
- Extended
throttle shafts not required
- Fits Offenhauser
3558 (small block Chevy) 3x2
intake
- Fits Edelbrock
5414 & 5418 (small block
Chevy) 3x2 intake
- For
this linkage with additional
auto-trans kickdown
capability, see 9246PRO-KD.
- To use with banjo
fittings, add 9086K spacers
- 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
virtually disappear 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 still allow
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
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
installation.
Every Stromberg
TwoStep linkage kit comes
with full instructions, and
further help with selection,
installation and tuning is
available at our Tech Center.
