1973-1979 Ford Hydroboost Kit

PRESALE- Ships in October

If you've pushed a '73-79 F100 hard - towing a trailer, navigating off-road terrain, or just driving it the way a truck deserves to be driven - you already know the factory brake system wasn't built for that kind of work. The stock vacuum booster does the minimum. This Hydroboost Kit does the job right.

Fat Fender Garage engineered this hydroboost conversion specifically for the 1973-1979 Ford F100, replacing the factory vacuum brake booster with a hydraulic system powered by your power steering pump. The result is stronger, more consistent brake pedal feel - the kind of stopping power that matches what this generation of truck is capable of when it's built properly.

Built for 4x4, Towing, and Performance

Vacuum-based brake boosters depend on engine vacuum to function - and that's a limitation. Under heavy load, high RPM, or modified engine setups, vacuum levels drop and pedal feel suffers. Hydroboost eliminates that dependency entirely. Your power steering pump generates the hydraulic pressure that powers the brake booster, delivering firm, reliable pedal response whether you're hauling a load down the highway or working a trail.

This kit is engineered for F100 builders who demand more from their truck — not just in how it looks, but in how it performs and how safely it stops.

Two Finish Options. One Standard of Quality.

The FFG Hydroboost Kit is available in two finishes to match your build:

• Raw - Clean, uncoated steel ready for your shop's finishing touch.
• Black Cerakote - A durable, heat-resistant ceramic coating that looks sharp and holds up hard.

Both options are identical in fitment, contents, and installation. The finish is the only difference - choose what fits your build.

Fitment

Designed and engineered exclusively for the 1973-1979 Ford. This kit requires a functioning power steering system - the hydroboost unit draws its operating pressure from the power steering pump. Confirm your truck is equipped with power steering before ordering.

Professional Installation Recommended

Hydroboost conversions involve your brake and power steering systems - two of the most critical systems on your truck. We recommend professional installation and proper system bleeding after install. Questions during the build? Our team is here. We're builders too, and we'll help you get it right.

The Brake Upgrade You Have Always Needed

The '73–79 F100 is a truck worth building right. If you're putting the time, money, and care into making it perform - the brakes need to match. The Fat Fender Garage Hydroboost Kit gives you the stopping power, pedal confidence, and engineering quality that this truck deserves.

Stop harder. Build smarter. Drive with confidence.

The FFG Hydroboost Kit is designed for the 1973–1979 Ford F-100 and integrates with your existing power steering pump to deliver consistent hydraulic brake boost. This system is particularly well-suited for trucks running 4x4 drivetrains, tow setups, or performance engines where vacuum-driven brake assist is unreliable or insufficient.A properly functioning power steering system is required for this kit to operate.
