High Torque Starters for Classic Ford Bronco V8

Our High Torque Mini Starters are an ideal replacement for the factory starter on your classic Bronco.  These starters are considerably smaller and lighter than the factory original Bronco starter, but they offer a marked increase in torque.  This increase in torque provides much better starting power.  The small footprint of our starters make them easier to install (they can be installed with headers in place) and also allows for better clearance in custom applications where space is a factor.

Frequently Asked Questions

What starter motor fits an early Ford Bronco?

Starter fitment on the early Bronco depends on the engine and transmission combination. The 289, 302, and 351W engines use a specific Ford starter that mounts to the bellhousing on the passenger side. Replacement starters are available as direct OEM-replacement units and as high-torque gear-reduction starters, which are popular upgrades for higher-compression engines and trucks that see hot-start issues. There are two different starters, depending on if you have a manual or automatic transmission.

How do I replace the starter on an early Ford Bronco?

Replacing the starter on an early Bronco involves disconnecting the battery, locating the starter at the bellhousing on the passenger side of the engine, removing the two mounting bolts, disconnecting the wiring at the solenoid, and installing the new unit in reverse. Access is generally straightforward from underneath the truck. Always reconnect the battery last after completing the installation.

Why does my early Ford Bronco have a hard time starting when hot?

Hot-start problems on an early Bronco are commonly caused by heat soak after shutdown, the starter motor sits near the hot exhaust and block, causing the motor windings to resist current. Upgrading to a high-torque gear-reduction mini starter dramatically reduces current draw and resolves most hot-start issues. A heat shield on the starter body further reduces heat soak on severe cases.

How do I wire a starter solenoid on an early Ford Bronco?

The starter solenoid on early Broncos mounts on the inner fender and has four terminals: a heavy battery cable from the positive battery terminal, a heavy cable to the starter motor, a small signal wire from the ignition switch, and a small wire to the coil (I terminal). If wiring a replacement solenoid, use the factory wiring diagram for your year to ensure correct terminal identification.

What is a high-torque mini starter and do I need one for my early Bronco?

A high-torque mini starter is a compact gear-reduction unit that produces more cranking torque while drawing less current than the original starter. It's a worthwhile upgrade for early Broncos with rebuilt or higher-compression engines, and especially for those with hot-start issues. Mini starters are also smaller and lighter than the original, improving clearance in tight header installations.
