The Right Stuff 1973-87 GM & GMC C/K Truck, Hydro Boost Upper Assembly Kit Disc/Disc - (GHB730572)

A ready-to-mount hydro-boost upper assembly for 1973-87 GM and GMC C/K trucks with disc brakes at both ends. The booster comes paired with a cast-iron dual-port master cylinder. The pedal rod extension, bracket and hardware are in the box, so you can mount the whole assembly and start plumbing lines. Because it runs off power steering pressure, it's a strong choice for square-bodies with diesels, big cams or anything short on vacuum.

Why It's Worth It

• Hydraulic booster provides consistent assist without relying on engine vacuum.
• 1" bore cast-iron master cylinder, dual-port, matched to a disc/disc system.
• Includes the pedal rod extension, so you don't have to rig the pushrod yourself.
• Bleeder hoses included for bench bleeding the master before it goes on the truck.

What's Included

• Hydro-boost booster
• Cast-iron master cylinder with cap
• Brake pedal rod extension
• Mounting bracket and hardware
• Bleeder hoses

Before You Order
