- Maximum 5-3/16 inches from carb to carb
- Extended throttle shafts not required
- Fits 4-cylinder Equalizer and Riley Two Port 2x2 intakes (5in)
- Fits most 2x2 adapters designed for 4bbl carb intakes (5-3/16in)
- Fits Vern Tardell Slingshot 2x2 adapter (5-3/16in)
A competitively priced 2x2 carburetor linkage with Superlink levers (click more
for applications and details). This linkage is sized for use with
intake manifolds and manifold adapters that space the carburetors 5 to
5-3/16in apart, including most '2x2 into 4-bbl' adapters, and the Vern
Tardell Slingshot 2x2.
It can also be used for early Ford
4-banger (Model A/B engine) 2x2 intakes, which place the carburetors 5
inches part. See above for typical manifold applications.
specialist Charlie Yapp tells us, "Ford Model A and B type engines are
mounted in the frame at 4 degrees tilt to the rear so the manifolds have
a 4 degree angled mount to keep the carburetors level. The "Equalizer"
and "Riley Two Port" dual intake manifolds feature a mixing plenum so
the customer can set it up with two functioning carbs linked directly or
with a progressive linkage. It will also work quite well, on the
street, with one dummy carb at the rear and the functioning carb
forward. Why? The reason goes back to the 4 degree tilt. If any raw fuel
finds its way into the manifold it will run backwards, giving the
liquid fuel more time to be evaporated before it goes into the rear
Siamese ports. Of course . . . the raw fuel would degrade the
performance and cause a rich situation. If the carbs are set up and
jetted correctly there would be no liquid fuel."
manufactured exclusively by Stromberg Carburetor, this linkage combines
clean, traditional looks with maximum leverage. TwoStep linkage kits
come pre-assembled and install in just two simple steps, without the
need for extended throttle shafts. These kits are not a ‘one size fits
all’ solution. Different intakes use different carb spacing, so we model
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:
- Long die-cast zinc SuperLink lever arms. All other parts stainless steel.
- Extended throttle shafts are not required.
Stromberg ‘Snapback’ throttle return springs, which wrap around the end
of the throttle shaft. These chemically blacked, stainless steel
torsion springs snap the carburetors shut, yet virtually disappear from
- For a smooth, lightweight look, the swivels are
positively fixed by a small e-clip on the back, and the small black
set-screws on the front have knurled ends for a strong fix on the
