Its like Christmas around here (maybe worse) I have boxes here and more on the way from ORD, WFO, Ruffstuff, Yukon, CK5, Aces fuel injection, Parts Geek. I am "trying" to hold off until I get the Samurai up and going but the struggle is real lol.

"Lock Jaw" the 1979 Stepside

Going to pick these up Sunday, 37x13.50r15 M16 swampers on Spyderlock ATX beadlocks
couple more pictures of the tires/wheels i picked up
I am debating on gear ratios and could use some words of experience.
Currently have the TH350 with a fan cooled auxillary cooler, with 3.73 gears and gonna be running 37's. Dana 44/12 bolt with chromoly shafts. Most driving will be highway and mountain roads.
The 3.73's would be ok on the highway but I don't want to burn up the transmission off pavement.
I was first thinking 4.56's which would be good off pavement but would put the RPM's higher on the highway.
Or go middle ground with some 4.10's but it just seems like a waste for moving one gear ratio lol.

I’m running 4.56 with 35s and a TH400 (not a 350 but also non OD) no way would I go to 4.10 to run 37s. In fact if I was going to run 4.10s with 37s I’d look for a 14bff and 60 that already had 4.10s. At 70 mph it’s a 300 rpm difference between 4.10 and 4.56.
I vote 4.56
I vote 4.56
I ran 4.88’s with 37s and a th350. 70mph was around 3500rpm. It was high and the engine would start leaking from the breathers if I was on the highway too long. Never had an issue over heating though.
Similar to the above mentioned difference between 4.10 and 4.56, going from 3.73 to 4.10 won’t make much difference for the money and/or effort spent. I’d go with 4.56’s so you’d have a noticeable change.
I’ve run 4.56’s and 35’s in an old daily driver that had a stock 100k+ 350 and the gears made it feel “normal” instead of being a dog because of the tires.

Are you running a 205 case? If so you’ll definitely appreciate the 4.56s, as low range is pretty paltry at 1.96:1
I've got 37s with 4.10's in my 1-tons, and it's definitely a bit of a compromise, but that's what the 14B came with. That being said I can pull most mountain passes in fourth gear, with a 350 with 325 hp. Having an SM465 definitely helps with getting started on steep stuff. Plus I don't rush on the highway, cruise around 65mph.
With your auto I would go with 4.56's

Right now it's a 203 but I'm looking for a 205 that fits the budget
Thanks for all the input guys, you have re-enforced what I was already thinking
I have a 14BFF sitting here for it, just need a Dana 60 to fall from the sky for less than $1000 lol
But then I need everything again, wheels, gear, lockers, shafts, blah blah blah

203 is the same paltry low range, just heavier lol
Ya the Toyota, jeep and samurais are nice in that aspect, there's a lot more transfer case gearing options. Even without a doubler my samurai t-case has 6.4 gears. Running a 203/205 doubler and your still only at 4 to 1 which you can get out of a stock Rubicon. My doubler going in my Cherokee puts the gear ratio at 7.4 to 1.
Now... The 203/205 is stronger but also weighs more than all the others (maybe combined lol)
NP241/NP205 doublers are better than NP203/NP205's.

the truck has just been sitting while parts piled up inside it. Last February I ordered an A-bomb bumper from DIY4X, in July they went out of business but i was told mine would still be coming, it showed up last week. That was the last piece I was telling myself as an excuse I was waiting for to get started lol. Well this weekend I found a parts rig for the truck and of course it changes the plans a little...
Dana 60
H1 wheels
Came with a new electric winch, new hydraulic winch, shackle flip, ORD front body mounts, new fuel tanks, and a DIY4X aluminum dash
so the gears, lockers, chromo axle shafts, crossover steering, diff covers, and 37's on beadlocks will probably be going to my kids 72 K5 blazer or maybe my CJ6. I may be picking up another "parts rig" which may end up making the stepside the parts truck lol.
But now I am back to just needing time and motivation and now money again for steering, better tires, lockers, gears...

Dodge 60? I see what looks like 1/2 wheel studs and external hubs
It's internal hub, no bolts on the hub
Good eye
I cleaned the crud off the BOM, 1977.5-1978 K30 with 4.10 gears
