• Cross-reference part numbers: 52-7374, 1C3Z2005AA, 2C3Z2005BB, 5C7Z2005B, F81Z2005AA.
• Always compare mounting points and connector locations with your original unit before ordering.

How does this hydraulic booster improve braking feel?

Instead of relying on engine vacuum, this booster uses hydraulic pressure from the power steering system to amplify pedal input. The result is smoother, stronger assist under heavy loads and towing conditions where vacuum boosters may struggle.

• Provides consistent assist when under towing or hauling load.
• Improves pedal modulation for controlled stops with heavy trailers.
• Engineered to match OE response so braking feel remains familiar.
• Tested for pressure and leakage to ensure reliable performance.

What should I know before installing the GDUKOP 52-7374?

Installation requires reusing several components from your original booster: the pushrod, spring, and spring retainer are not included. Proper bench measurements and following manufacturer torque specs will help ensure the booster functions correctly after installation.

• Pushrod, spring, and spring retainer must be transferred from the original booster.
• Confirm brake line and hydraulic port locations match your truck before purchase.
• Bleed hydraulic lines per vehicle procedure after installation for proper assist.
• Use OEM torque values and follow safety steps when removing the master cylinder and booster.

How durable and reliable is this replacement part?

Made with precision cast iron and manufactured to meet OE-style specifications, the booster undergoes performance checks for pressure and leakage. The robust construction aims to deliver long service life in demanding truck applications.

• Cast-iron body for strength and resistance to wear.
• Pressure and leak-tested during production for quality control.
• Designed to match original mounting and hydraulic interfaces for a straightforward swap.
• Corrosion-resistant finishes where applicable to prolong life.

Who is this for? This GDUKOP hydraulic power brake booster is intended for owners, mechanics, and fleet managers replacing a worn or failed hydraulic booster on compatible Ford Excursion and Super Duty trucks. Choose this part if you need a direct-fit replacement that restores hydraulic-assisted braking performance and is built to OE-style standards; confirm fitment and reuse the original pushrod and spring for correct installation.
