To be honest, it feels like our modular linkage kits for Stromberg 97 carburetors on Edelbrock, Offenhauser and other 4×2 and 6×2 intakes have been in development for years – and in truth they probably have. But now they’re at the warehouse ready to go. And we’re double proud of them. Eight new direct and progressive kits for commonly available 6×2 and 4×2 intakes, plus versatile Trim-to-Fit kits covering the full range of vintage applications.
It goes without saying that they are all developed from scratch, in-house. And it was no easy task. If you want quality linkages (ie. with rod ends), multi-carb linkages are a real challenge as almost every intake differs in carburetor spacing, width and the offset between the two banks. How do we cover all those bases? With tailored solutions for those intakes still available new, like the Offy Pacesetters and the Edelbrock X1 ram, plus Trim-to-Fit options, which cover pretty much everything else out there. Unlike many a linkage, ours come pre-assembled with full instructions – including ‘Trimming to Fit’. Each kit comes in a cool zinc/stainless finish but chrome and polished stainless is available to special order.
So here’s the deal: The direct (non-progressive) linkages are supplied as complete kits with our Snapback return springs. And the 6×2 progressive kits are modular, so you simply purchase two 3×2 progressive kits from our current range to suit your carb intake spacing, then add the new Back-bar Kit to link both carburetor banks together.
At the heart of the new systems is our unique low-line Back-Bar brackets that won’t over-whelm your shiny new 97s. Precision rolled in stainless steel and reamed for the Oilite self-lubricating bushes, they support the Back-bar shaft at BOTH ENDS for zero flex and positive operation. You simply cannot say that if your Back-bar is supported at one end only. With so much return spring involved, the free end of the shaft flexes like crazy without full support.
All our Back-bar levers are clamped AND PINNED onto the shaft. With ‘3-position’ adjustment, you can alter the leverage and throttle response, too. And our stainless Back-bar end stops prevent lateral movement. We strongly recommend a mechanical link to the pedal with any 4×2 or 6×2 system, so we’re also making our long Back-bar levers available separately as kit 9096K. Complete with swivel, clamping screw and 3/32” roll pin, they can be drilled and pinned to the Back-bar to ensure positive location and correct alignment with your pedal pull point.
We’re putting all the new kits onto our website this week, so you can check them all out here…Stromberg TwoStep Linkage Kits. And we’ve also posted the full Installation Guide onto the Stromberg Tech Centre right here…TwoStep 4×2 & 6×2 Linkage & Back-bar kits Installation Guide
