I'm using stock Explorer with 35" tires and it works great. If I ever do upgrade, I'd go with a Lee's reworked Explorer pump turned into a saginaw...but I doubt I'll ever need to.
Me too. I don't push my rig anywhere as hard as @nvrstuk but my stock Explorer pump etc as described above has gotten me through the Rubicon twice without issue. My truck used to be too pretty for that until those trips. Lol.

I created a frankenpump many years ago out of an Explorer p/s pump casting and Super Duty guts (from a donated SD pump, a variant on a C3). It boosted max output pressure from IIRC about 1300 psi to around 1800. I didn't have a way to measure flow rate. I ran it for awhile but the shaft seal blew out. Probably due to it being dried out, since it was the one on the S/D shaft and should've been up to the task. Still have it on my parts shelf. Back to the same (fingers crossed) used Explorer pump I've been using for over 20 years. It can't last forever but it seems to be threatening to.

Well, I was doing some PS stuff a while back and decided to just get another pump from Oreilly Auto. I paid $62 but looks like it's $99 now. It does have a "Limited Lifetime Warranty" though.

Lifetime warranty to me means you need to buy spares of every part so you can fix your rig and not be stranded on the side of the road. :) Where I live it usually takes a couple days to get my "lifetime warranty" part replaced.

I remember that trip on the Con where you took your Bronco from super capable and super nice to super capable... :) Then you made it Super Nice again! That was a fun trip! :)

Learned all about "Lifetime Warranty" parts with a Pep Boys (remember them?) water pump. Translated what that meant was you're replacing them every 6-9 months. Got tired of that after the second one and that's when I found Stewart Components water pumps and I haven't looked back.

I've ran a few different pumps with my explorer serpentine conversion over the years. I've been running this WIldhorses setup for a few years now and can't imagine anything much better. It turns my 4X4X2 box, Hydroboost and 35's like butter https://www.wildhorses4x4.com/high-volume-dual-return-power-steering-pump-v-belt. You'd just need an adapter bracket and swap the v belt pulley for a serpentine one

I don't, Paul. But I still have a copy on my hard drive. Gawd. Seems forever ago. I learned a lot in a couple of days.

I've called them too. Sad thing is that they make a pump for the late Mustang, which is the same pump body. They'd just need to make the Explorer fan/pulley hub to have an Explorer pump.

I wonder if belt spacing is the same? You could use a different fan and make it work.
Unfortunately, most of those other options wouldn’t be as good as the explorer fan. But maybe something out there has a big 10 blade fan with similar engineering, that just bolts to a standard hub.
