Did you do the 180 flip of the springs, or just move the whole assembly back?
H55F + split case + tc mounted ebrake =?

Yes. However they also recquire a high range REDUCTION of 10% and are quite a bit louder then the 3:1, and 99% of new builds are not hardcore enough to need that much transfer case gearing so I don't really push them that much

My split case I had 3:1 installed but asked for 4:1 and was recommended that with my build 4:1 was over kill. But the 4:1 was available.
Done both over the years. On my othet H55F 40, I run FJ60 rear springs for the added length and improved ride.
How far back does it push the axle and do you need to modify the wheel well with the 60 springs? What did you use for the front springs when using 60 springs in the rear. Lastly, was the springs stock 60 or lifted 60 springs in the rear?
I have given thought to flipping 189, but was not sure how much the ride quality diminishes? An H55 is definitely on my wish list!

Longer wheel base will improve the ride. Rear axle further back will decrease the approach angle a little but improve the departure.
The BF1 split-case offers the highest number of options when compared to 1PC and HF1/HF2 variant t-cases. Strong case and a 7+ (rounding) different gear combinations

Approx 5", and yes I re-worked the wheel wells to suit. It's been 25 years (almost to the day) that I was doing the work so the exact numbers are a tad fuzzy
There are some additional details and pics here:
With the critical build parts acquired (tub, frame and axles), I brought the tub to Cruiser Outfitters (in SLC proper at the time) and got to work.
(my prized tub on a random rolling frame/chassis so I could move it around to work on it)
I had two parallel tasks right off the bat, frame modifications and tub sheet metal work. The donor frame was propped up on jack stands in corner of the shop and I got to work cleaning off any unnecessary brackets and mounts, i.e. the factory steering gear pedestal, leaf spring mounts as I was going to SOA/SR, etc. I started setting up the...

I flipped my rear springs probably 15 years ago, when I centered the rearend and went to a centered rear output tcase. I didn't really notice any differences in ride or offroad capabiities from driving it. Obviously there was an improvement, but it wasn't anything earth shattering or noticeable. And yes, you have to cut the wheel opening. You've moved the axle back about 3".
I don't love just flipping the 4x rear springs.
In stock form, when the axle droops, the axle pivots on the short side of the leaf spring so the pinion angle increases, staying in better orientation with the t-case. Likewise when the axle compresses, the pinon angle lowers, again staying in better alignment with the t-case.
However with the springs flipped and the axle working on the long side of the spring, it's the opposite. Down travel increases the pinion angle, the opposite of the desired effect particularly with a short rear driveline and lots of flex. Totally workable as proven by the many running that but I like the 55/56 or 60/61/62 options more, but they are more work/parts too.
Good to know. I don't have a long or short side. I needed the added wheelbase to get a decent driveshaft angle. The tcase centered rear output is several inches higher than the stock offset rear output tcase.
Thank you Sir, always great to see optionsApprox 5", and yes I re-worked the wheel wells to suit. It's been 25 years (almost to the day) that I was doing the work so the exact numbers are a tad fuzzy
