I just installed this starter to replace the stock version. Instructions very clear and simple except on my install the bolts that were on there was too short for the new starter. No problem just picked some up a half inch longer and was good to go. This starter is also quieter than stock so better sounding too.

Why a Gear Reduction Starter a Smart Upgrade for Your Early Bronco

If you've owned a classic 1966–77 Ford Bronco for long, you’ve probably experienced that sluggish grind when starting the engine - especially in cold weather, after a long trail day, or when you're running a high-compression build. It's frustrating, unreliable, and the last thing you want to deal with on the trail or at a stoplight.

That’s where a gear reduction starter comes in. It’s one of the most impactful (and underrated) upgrades you can make to your early Bronco. Here’s why ditching the original-style starter for a gear reduction model is a smart move.

More Torque, Less Draw

Traditional factory starters rely on sheer motor size to turn over your engine. A gear reduction starter, by contrast, uses a smaller, high-speed motor that spins a set of reduction gears. These gears multiply torque while keeping amperage draw low. Translation? It spins faster, turns stronger, and doesn’t suck down your battery.

This is especially important for classic Broncos that might not be running modern charging systems—or when you're deep on a trail and need a reliable crank after a long crawl.

Compact, Lightweight Design

Gear reduction starters are typically 50% lighter and significantly smaller than original starters. That means:

  • Better fitment around tight headers or custom exhaust setups

  • Easier access during installation or trail repairs

  • Less overall weight over the front axle

The smaller size also reduces heat soak issues common in tight engine bays, meaning it’ll perform better after long runs when heat builds up under the hood.

Easier Cold Starts & High-Compression Compatibility

The extra torque from a gear reduction starter is a lifesaver on cold mornings or when trying to fire up a higher-compression V8 build. If you’ve upgraded your engine’s internals, increased compression, or bumped up cubic inches, your stock starter just isn’t built to handle that kind of load.

Gear reduction starters are designed for modern performance demands while still fitting the classic engine layout of your early Bronco.

Better Clearance = Fewer Problems

Early Broncos aren’t known for generous engine bay space. If you’re running long tube headers, aftermarket oil pans, or a custom suspension setup, every millimeter counts. Gear reduction starters tuck up tighter to the engine, offering superior clearance compared to bulky OEM-style units.

That added space could mean the difference between a clean install and a frustrating wrench session—or worse, a melted starter from resting too close to hot exhaust.

Reliability That’s Ready for the Trail

Modern gear reduction starters are built with high-quality internals—precision-balanced armatures, hardened gear teeth, heavy-duty solenoids, and corrosion-resistant casings. They’re also endurance tested to handle the kind of real-world abuse that off-roaders and weekend drivers alike throw at their trucks.

For Bronco owners who value confidence and simplicity, that’s a huge win.

Bottom Line: It’s a No-Brainer Upgrade

For most early Bronco owners, switching to a gear reduction starter is a bolt-on upgrade that delivers:

  • More starting power

  • Less battery strain

  • Better clearance

  • Increased reliability

Whether you’re building a trail rig, a daily driver, or a show-quality classic, a gear reduction starter is the kind of smart upgrade that just works. And when your Bronco fires up every time—no matter the weather, altitude, or terrain—you’ll be glad you made the swap.
