This is a brand new hydraulic power brake booster for your 1999-2005 Ford Super Duty trucks and Excursion.

We're talking F-250, F-350, F-450, and the Excursion up to 2005.

It's built from cast iron, finished in black, and comes with all the goodies you need: the booster itself, an o-ring kit, and an instruction sheet.
The manufacturer part number is BB15006, and it crosses with a bunch of numbers like 52-7374, 1C3Z2005AA, and 2C3Z2005BB.

It's a direct hydraulic replacement, so no master cylinder is included—just the booster.

The housing diameter is about 2.158 inches, and the studs are 3/8 x 16.
Plus, it's been 100% sealing tested, so you know it's ready to bolt on and work.
Just a heads up, there's a Prop 65 warning for California, but that's standard for a lot of auto parts.

This booster is heavy duty, weighs around 16.5 lbs, and comes with a 1-year warranty.
If your brakes feel mushy or you're losing power assist, this is the fix.

Get your stopping power back with this solid, unbranded but high-quality unit.
Make sure to double-check the fitment notes for your specific year and model, but if it matches, you're good to go.
