Installing JBA headers

Hello to all. I am new to this forum and deciding to start some upgrades on my ranger. I have a 01 Ranger Edge. I am getting my JBA headers in this coming week and am wondering how difficult it will be to install these and if there is any prep work that I will need to do to my truck before I go to take the stock system off and put these on? Thanks in advance.

I don't know if you have a 3.0L or a 4.0L. I installed a set alone on a 4.0L and it took the better part of a day. Some say it's a weekend job and that probably depends a lot on how much you have in the way of tools and equipment available. Universal sockets, ratcheting box wrenches, and other close quarters tools will make the job much easier. A hoist would have helped but I don't have access to one.

IMO, it is best to completely remove the front tire/wheels and plastic inner fenders, at least on the 4.0L. This gives you the access and the visibility to get the job done. Be sure to soak the exhaust fasteners in PB Blaster or an equivalent penetrant well before you start disassembly.

I ground a small bevel on the passenger side collector flange to open up a little clearance to the oil filter adapter. It may have been possible to make it work without the bevel but I had heard that other people had trouble with contact or interference between these parts on the 4.0L Ranger. This is not an issue if you have a 3.0L.





The finished installation:

Isn't there some method you need to go through after installing them, like after you run the engine for a few minutes to heat it up, let the block cool and then re-tighten all the bolts? It helps you get them as tight as you can to avoid exhaust leaks.

Since I bought mine used without instructions, I don't know what JBA recommends. I did heat cycle and retighten them twice and haven't had any leakage in about a year and a half since the install. Good point!

yeilds very lil extra power without a few other mods. I don't know exact numbers, but the general concensus is that it's not worth it, bang for buck. If you can get a used set like Bob however... different story. I think to make a bigger difference it requires block mods, intake and other exhuast upgrades.

as far as rangers go, it's usually one of the last mods to be done, under the hood.

On a Ranger 4.0L, JBA claims that their headers, catback and wires together are good for 16 HP max.

Thanks for the help. I'm sure it won't be a problem with all the advice. I will also be putting on flow master 40 series exhaust (not myself), intake, electric fan, and an x calibrator hopefully all next weekend. I am ordering it all tomorrow. Hopefully everything will go smooth. If anybody has anymore pointers on the headers or anything else keep em' coming. Thanks for the help.
