Hydroboost questions

[chris85]

What diameter master cylinder is everyone using with their hydroboost swaps? Ordered a kit from Sweeting and they mentioned going with the larger diameter (forget the actual size) MC bc of the 1 ton axles. Is that going to make any difference? Maybe a shorter softer feeling pedal? It has disc's all around; JB6 calipers upfront and JB7 in rear.

when i did the swap 20+ years ago i just used the doner k30 setup with the dana 60 front and 1/2 ton rear calipers and an adjustable prop valve to rear and few test drives i was happy . could lock up 38" swampers .

Cool. I assume the K30s have the bigger diameter MC so thats good to know. Thanks!

Yep, been out of the game a while. But finally got a place that I dont have to swap the tires out every time I want to drive the thing. Time to get back to work

@chris85 are y'all in Vicksburg (profile location) or still in Sumrall?

We're in Sumrall now. Just finished the house in Feb

Damn! I missed the part when I ordered that there is a 90 day lead time.

You might try hooking up what you have and see what happens. I run a D60 and AAM 10.5 1 ton setup, disc, disc with the stock blazer master and it works fine. Locks up 37's and I don't even mess with the proportioning valve I put in the rear. Better than waiting 90 days to drive.
