New Stromberg linkages – 6×2 & 4×2

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

  1. ok so where can i get the 6×2 linkage i have 6 ford 8BA carbs on an offy intake i guess these are the same as the strombergs 97’s

    • Hi Wayne, Go to the dealer page on our website (click the link) and choose a dealer that suits your location. I have not tried the 8BA Holley type carbs personally so I cannot confirm on clearances etc, but the dealer can help with that.Thanks.


  3. I have a Wieand WC4D stagger intake with Stromberg 94s on it. I want to replace the linkage. It looks like you have them but I can’t tell ifs the same linkage I need. What would that run me?

    • Tim, 94s are Holley carbs. The principle is the same but the throttle shaft spins the opposite way. On a 97, what you need is two of our 9136K Throttle shaft extension kits ($25.95 each) though we have not yet tested them with 94s. These extend two of the shafts over to the far side so you can then link all four together in a line. Use four of our 9091K levers ($15.95 each) and get yourself a length of 3/16inch OD stainless rod to join them together. They take a little time to get everything in alignment and snapping back on the throttle springs cleanly, but it can be done. There is a How-To article on the Stromberg Tech Center –

  4. Hi I just purchased an offy intake (4X2) with new Stromberg 97’s but I havnt found any linkage for yet? Thanks for your help!

    • Hi Todd, I have emailed you as we need to know whether this is 4 carbs in line or staggered. Once we get that info, we can advise on linkage. Whatever, we have all options covered. Thanks!

  5. Good morning!
    Running a Weiand W245 with 4 97’s in line.
    Would appreciate a linkage solution.

    Thank you!

    • Hi Ron, This shouldn’t be a problem. We have 4×2 direct and also a progressive using the two centre carbs are primaries. I will email you. Thanks for your enquiry!

  6. Hello,
    I recently purchased an Offenhauser 4 X 2 intake manifold from Speedway Motors for a small block Chevrolet. Speedway does not sell the carburetor linkage, The carbs will be Stromberg 97s. This intake manifold has the carbs in line front to back but from side to side they are staggered a bit to allow for fuel lines. Where do I find and buy the linkage for this setup. Thank you for your help.

    • Hi Paul, I am sure we have a 4×2 linkage for your application. Check our website. Your intake is probably the Offy Pacesetter 5024, in which case you use the 9271-D linkage. The website also lists our dealers. Thanks.
