full 6x2 progressive linkage.
Designed and manufactured exclusively by Stromberg Carburetor, our Back-Bar kits change the game for quality, efficiency and looks.
With so many different multi-carb intakes and applications available, Stromberg 6x2 progressive linkages are modular, allowing you to
select you 3x2 Progressive Linkage and Back-bar kits separately to suit your individual intake manifold dimensions.
You’ll find comprehensive information on choosing and installing the right kits for your multi-carb intake at the Stromberg online Tech Center.
Each kit comes pre-assembled and installs in simple steps, without the need for extended throttle shafts. Every Stromberg TwoStep linkage
kit comes with full instructions, of course, including how to measure your intake and 'Trim-to-Fit', including how to pin the levers to the Back-bar shaft.
This Trim-to-fit Back-bar Kit can be used on intakes with the following maximum dimensions:
Carb spacing on each bank : 5-1/2 inches maximum
Distance between the two banks: 9-1/8 inches maximum
Offset – how far one bank is in front of the other: 1 inch maximum. Trim-to-Fit kits are supplied with one long and one short Back-bar bracket.
You leave the short one alone, and trim the long one to suit your own offset.
IMPORTANT NOTE: Our pictures show a full 6x2 linkage when assembled. Carburetors and manifold not included. This kit comprises only the following:
- 2 stainless steel Back-bar brackets with rolled ends, Oilite self-lubricating bushes and two small washers to take up any height difference in the base castings.
- Stainless steel Back-bar shaft.
- Two long levers, with swivels and clamping screws. One lever is pinned to the shaft. The other is drilled for a 3/32 inch roll pin (supplied) allowing you to position this lever to suit your intake width.
- Two stainless steel end stops to prevent lateral movement in the Back-bar shaft.
- Two stainless steel rods with swivels – the links between the Back-bar levers and the primary carburetors.
Designed for maximum versatility in operation, our 6x2 kits can be configured in a number of different ways. The long back-bar levers have three top mounting
points for flexible throttle response and leverage. And the progressive links can be adjusted to run the engine using just two, four or all six carburetors.
For more information, check out our 6x2 Tuning Tips at the Stromberg Tech Center.
Stromberg recommends a mechanical pedal link for all multi-carb systems. Your 6x2 Back-bar can be connected to the pedal via one of the two long levers supplied,
or you can add a further long lever with Stromberg kit 9096K (Long linkage arm/swivel) which can be positioned anywhere along the Back-bar shaft to align with
your throttle pedal ‘pull’ point. Complete with swivel, clamping screw and 3/32 inch roll pin, the extra lever can also be drilled and pinned to the Back-bar to ensure
positive location.
Please note: This kit will not fit Holley or Edelbrock 94 carburetors as the idle mix screws are on the back where the brackets fit on the 97.
