TwoStep 3×2 Linkage.
4-7/8in carb spacing

A competitively priced, 3×2 carburetor linkage with clean, traditional looks, die-cast Superlink levers and a stainless steel link rod.

Use on intake manifolds with carburetors 4-7/8 inches apart. If in doubt, simply measure your manifold spacing – throttle shaft to throttle shaft.


Exclusive to Stromberg Speed Parts, this linkage features ‘Snapback’ throttle return springs which virtually disappear from view. 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 stainless rod.

The linkage comes pre-assembled, installs in just two simple steps and comes with full instructions. Click the other tabs for help with installation and tuning.
