Part No. 9251PRO-KD
A premium 3×2 progressive carburetor linkage designed for optimum performance and versatility. Use on intakes with 4-7/8in carb spacing. If in doubt, simply measure your manifold spacing – throttle shaft to throttle shaft.
Exclusive to Stromberg Speed Parts, this linkage features our ‘Snapback’ throttle return springs which virtually disappear from view. Special swivels and bolts clamp the rod ends tight, yet still allow full rotation. The small bolt has a blind hole, allowing you to insert eg, a hex key, to tighten the lock nut.
The extended center lever has a 1⁄4”UNF thread, which accepts the special fixing common to most (eg ‘Lokar®’) hot rod auto-trans kickdown cable kits. Stromberg KD linkages are designed to work with the Stromberg Cable Throttle Bracket (9136K).
The tapered rod stops are fully adjustable, with discreet set screw fixings and opposite threaded rod ends ensure easy adjustment. Just spin the secondary link rod to adjust for the correct lever angles.
The linkage comes pre-assembled, installs in just two simple steps and comes with full instructions. Click the other tabs for help with installation and tuning.
WARNING! To use this linkage with banjo fuel fittings, you must add our 9086K banjo fitting spacers to ensure safe clearance between the long lever and the fuel line. Always read the instructions before installation.
WARNING! Always check that your vehicle’s automatic transmission and kickdown cable are compatible with the Stromberg KD linkage. Different transmissions have specific kickdown requirements and incorrect set-up can result in transmission damage.
