Description
Stromberg Progressive Linkage Back-Bar Kit Fits Edelbrock X1
This Stromberg Progressive Linkage Back-Bar Kit is designed specifically for the Edelbrock X1 6×2 intake and is used with Stromberg TwoStep Progressive Linkage systems to build a complete 6×2 progressive carburetor setup.
Designed and manufactured exclusively by Stromberg Carburetor, these modular Back-bar systems deliver smooth throttle operation, clean traditional styling, and the precision needed for serious multi-carb hot rod applications.
With so many intake designs and carb configurations available, Stromberg engineered their 6×2 linkage systems as modular components, allowing builders to configure the perfect setup for their individual manifold dimensions and driving style.
Every kit comes pre-assembled for straightforward installation without the need for extended throttle shafts. Complete instructions are included, along with setup and tuning information through the Stromberg Tech Center.
Designed For Edelbrock X1 Intakes
This Back-bar kit is configured specifically for the Edelbrock X1 6×2 intake manifold and delivers smooth progressive throttle operation across all carburetors.
The modular system allows progressive linkage tuning for:
- Two-carb operation
- Four-carb operation
- Full six-carb operation
Multiple mounting locations on the Back-bar levers allow throttle response and leverage adjustments to suit your engine combination and pedal feel preferences.
Kit Includes
- Stainless steel Back-bar brackets with rolled ends
- Oilite self-lubricating bushes
- Stainless steel Back-bar shaft
- Stainless steel linkage rods with swivels
- Long linkage levers with clamping screws
- Stainless steel shaft end stops
- Spacer washers for base casting height variations
- Installation hardware and instructions
Precision Stromberg Engineering
Unlike old homemade linkage systems that flex, bind, or wear quickly, Stromberg’s precision-machined stainless steel components are designed for long-term durability and smooth synchronized carburetor movement.
The clean Back-bar design also keeps the engine compartment looking traditional while delivering modern drivability and throttle response.
Mechanical Linkage Recommended
Stromberg recommends using a mechanical pedal linkage with all multi-carb systems. Additional linkage arms can be added anywhere along the Back-bar shaft to properly align with your throttle pedal pull point and geometry.
