E350 Quigley Brake Upgrade possible ?

[doublevan2]

Greetings -- seeking info from anyone who has done a brake upgrade on a Quigley - E350 EB - V-10 - 2000 to 2002 vintage.

Running at around 10,500 loaded for "bear" travel - I found it sometimes challenging to come to a stop - specially when DOT engineers decide to place stop signs or stop lights at the bottom of hills coming out of hill country or the mountains !

Would love to hear from anyone who has done this (date done/year done) re parts, suppliers, prices, "did it work" after thoughts, etc.

Thanks !

There’s a few threads that address this. It is possible to upgrade, but yes, Quigley conversions require you to redrill the rotors to 8 on 6.5
You can either source replacement rotors from Quigley or get upgraded aftermarket rotors and have them machined. I upgraded to cryo frozen slotted rotors from Frozen Rotors and had a local machine shop drill them for our 8 on 6.5 fitment, I ordered rotors specific to my conversion, in my case, a 2003 F-350 D60 front axle which is normally 8 on 170 before Quigley converts the hubs/rotors to match the van rear end.
There are other quality rotors and big brake kits out there, maybe someone else can chime in with other options.
Hope this helps
