Another LS Swapped 40

[FullyLitLED]

Hey guys,

Posting this just to document the process.

This FJ40 had the original 2F in it.

Plans:
-5.3 LS with truck FEAD
-4L60 transmission
-Tcase (undecided)
-Holley Terminator X max (had great success with this recently

Pending:
-Shortened 80 rear axle


Currently have a mini truck power steering box…reason for this is to provide maximum clearance and no part of it obstructs any area between the frame rails. Space is at a shortage with LS swaps

Frame is coming apart soon so that I can get it blasted and coated! Frame has the shackle reversal already. Trying to keep this an OEM looking build but with a modern powertrain.

If you are doing all that work go with a 80 steering box, split transfer case, and flip the rear springs and it will drive amazingly well.
80 steering box will get you way better clearance and make a transformative handling improvement
Don’t get your chassis blasted and powder coated until the end. Huge mistake to do that first. That's the last thing you do, not the first.
Skip the narrowed 80 rear and just do a FJ60 axle, much simpler and easier.
I would undo the shackle reversal personally.

Thanks for the advice!!! I was reading somewhere that flipping the rear springs would add like 3 to 4 inches of wheelbase? Would mean for me to make it look right I’d need to redo the wheel arches?

Looks like you have body work to do anyways, if you do it right it looks good. Every time I show one we’ve done to a customer I have to explain that it’s not stock and it takes them awhile to even understand what I am trying to show them

If you don’t do this your rear driveshaft will be way too short.
