Guys on tons prop valve question

[moparcyco]

For those of you on tons with 3/4 or 1 ton brakes what are you using for a prop valve? I have a zj disc valve or is it going to matter with this much brake?. Tera 60's front, rear 14 bolt outers on rear with 3/4 ton chevy brakes front are 1 ton chevy. Thanks

99 XJ booster, Dodge 3/4t gasser master, ZJ ABS prop valve (one output F&R). Once I got the pedal dialed in, stops my big brakes great

I like a gutted valve with an adjustable proportioning valve on the rear brake line.

I should add I'm running 96 up xj dual booster with a master from a 77 grand marquis with 4 wheel disk. If it matters. Think I will try the zj valve and go from there.

Empty metering block, no valve.

50/50 does not work. Your rear brakes will lock up

Weird. Anytime ive gutted the block my rear brakes have locked up. It just about threw myself thru the windshield locking up 37s.
