This is a complete bolt in kit designed to work on 1966 to 1979 GM medium duty trucks that gives a firewall mounted 11" Super Duty power brake booster and 1.5" bore master cylinder. It's important that you confirm fitment before ordering by comparing my pictures and measurements to your truck. There may be variations in these trucks I am not aware of. This kit is meant for trucks that have a firewall mounted master cylinder held on by two bolts that are 3.625" on center, horizontally spaced.

You will notice a dramatic increase in braking power and pedal feel getting rid of your original system and going to this setup. 
This does away with the slave system and under mounted booster. This booster installs in about an hour and requires no cutting or permanent modification. It works with your existing brake pedal. You do need to add a proportioning valve. I don't offer this at this time but hope to around May 2024. A generic PV4 valve will work fine though.


This does NOT fit the earlier trucks with a 2 in 1 clutch / brake master cylinder and it does NOT fit the trucks with a firewall mounted master held on by diagonally spaced obls. To confirm fitment, please see the pictures here:

Super Duty Components:

This kit comes with a Super Duty 11" dual diaphragm booster and 1.5" bore Super Duty master cylinder. The Ford parts are excellent, reliable, and easy to source. These parts are 100% brand new and high quality throughout. The booster has a very nice black powdecoated finish that will last for years. This is the same setup that a modern F550 truck would come with. This booster/master setup will feel like it was factory engineered for your C60.

C60 / 6000 applications require an unusually long distance from booster to pedal connection. We take the brand new Super Duty booster, cut the rod in half, and tig weld on a machined steel spacer. The spacer is solid in the middle so the integrity of the booster rod doesn't rely on the welds- although you can expect great weld quality.

 

These parts put out about 1600 psi of brake fluid pressure as well as a large volume of fluid. This is a lot more brake fluid pressure than an original system, with about the same volume. It also has a mechanical advantage of directly mounting to your pedal rather than relying on a slave/master system.
