Back-bar for 6×2 Progressive Linkage. Trim-to-Fit.

Stromberg 6×2 progressive linkages are modular, allowing you to select the 3×2 progressive linkage and back-bar kits separately to suit your individual intake manifold dimensions.

This trim-to-fit back-bar allows greater flexibility, working on intakes with max dimensions as given above. If in doubt, measure your manifold spacing.

NOTE: Our pictures show a fully assembled 6×2 linkage. This kit is the back-bar only. Add two Stromberg 3×2 progressive kits to build a full 6×2 linkage.

The kit comprises unique low-line brackets with rolled ends and Oilite self-lubricating bushes – one long and one short. Trim the long one to suit the offset between the two banks of carbs. Supported at four points for zero flex, the stainless steel back-bar shaft comes with two end stops to prevent lateral movement.

Connects to your throttle pedal linkage via one of the two long back-bar levers, or a further one (Stromberg kit 9096K) added anywhere along the back-bar shaft to align with your ‘pull’ point. Stromberg recommends a mechanical pedal link for all multi-carb systems.

The linkage comes pre-assembled with full instructions on trimming, installation and tuning. Click the other tabs to preview.

Designed for maximum versatility in operation, our 6×2 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 linkages can be adjusted to run the engine using just two, four or all six carburetors. For more information, check out our 6×2 Tuning Tips at the Stromberg Tech Center.

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.
