Throttle

Tom's Offroad carries early Bronco throttle linkage components including gas pedal assemblies, accelerator cables, throttle rods, return springs, and carburetor linkage kits. Whether you're restoring stock throttle feel or upgrading to a cable-pull setup for an EFI or aftermarket carburetor conversion, the right components are available for 1966–1977 Broncos.

The 1966–1977 early Bronco uses a mechanical throttle rod linkage connecting the accelerator pedal to the carburetor. The system relies on a series of rods, pivots, and return springs to open and close the throttle plate. Over time, these pivot points wear and the return springs weaken, which can cause a sticky or unresponsive throttle that should be addressed for safe operation.

Yes, converting from the factory throttle rod linkage to a cable-pull system is a popular upgrade, especially for early Broncos with aftermarket carburetors or EFI conversions where the original rod geometry doesn't align. Cable kits offer smoother pedal feel and more routing flexibility. Tom's Offroad carries throttle cable conversion components for the early Bronco.

A sticking throttle on an early Bronco is most commonly caused by worn or binding throttle rod pivot points, a weak or broken return spring, a dirty or gummed-up carburetor throttle shaft, or a kinked throttle cable on converted setups. Inspect all pivot points, clean the carburetor linkage, and replace any worn springs or rods. A sticking throttle is a safety issue that should be addressed immediately.

Throttle linkage adjustment on the early Bronco involves setting the rod length at each pivot point so the carburetor throttle plate opens fully at wide-open-throttle pedal position without binding, and snaps closed completely when the pedal is released. Check that idle position leaves the throttle plate closed and that all return springs are intact and functional before test driving.
