LS swap radiators

[CamJake]

What is everyone using for their LS swapped CJs? My current set up is a cheapie alum rad/stock fan setup from the previous owner. I have a big Griffin 31x19 with dual Derale fans, but it’s huge and will require liberal grill trimming. Plus it’ll sit just outside of the frame rail which might look kinda odd.
My 5.3 is stock so the Griffin setup might be overkill...
What’s everybody running?

I ran a universal Griffin for a while until it started to leak. Then switched to a flex-a-lite that was designed for a CJ. Check out the write up in JPFreek Magazine.

I'm running an aluminum radiator for a Jeep from radiatorexpress.com. It's for the 6 cylinder but I have had zero issues even with no fan shroud. I was stuck in stop and go traffic in Chicago when it was 95 degrees and the temp never rose. They do have a Chevy swap radiator but mine was only a year old so I stuck with it.

No personal use with this on our swaps but I've seen a few lately and our next swap will use the
Flex-a-lite 51068LS Aluminum Radiator for Jeep CJ with LS Engine Conversion

I used this one and I think @Jeeperdd used the same one in his dads scrambler. Super easy install bolted right in. I cant remember the hoses but there should be a picture in my build thread and JeeperDDs.

Used an aluminum Northern brand CJ/Chev swap radiator. Its been years and there are better options out there now (see above), but the Northern unit has worked great so far.

My LS engine swap is basically stock. Do I really need an upgraded radiator like these? The Northern radiator looks like the cheapest option, but it's only a 2 row. Do I really need a 3 row? I also don't need a transmission cooler as I'm using an AX-15 manual transmission.

I have no idea if the stock radiator it is sufficient. Not sure I would trust that.
