Deciding on axles

[86MUDRCJ]

ton's wouldn't be a bad idea, though the initial expense will be more... i was just thinking that 31 spline 8.8's and d44's aren't all that uncommon... the 4bt stock isn't a hugely powerful motor, it's not bad, but it's not a powerhouse by many standards...

off topic, if you want to see what a 4bt can do, check out this car, i helped build it (if you look close enough, you will see pictures of me in the blog section of it...

Correct they are more common but do you think they could hold up to the torque put out by the motor?

I will say running y-long arms is nice and makes adjusting the axle and whatnot very easy. When I did my SAS I had never done anything it before. I did a year of research before I did my SAS to my truck. Dont be afraid to do something to your vehicle that you want to do, but make sure that you can do it though i.e tools resorces, etc... and have all of those things at the ready.

I will say 1 tons seem like a bit over kill but you never know.

I am reading all i can about sas and it's hard to remember all this stuff.lol 1 tons do take it overboard a bit but what other options would i have?

Nope, I do not think a d35 and 8.8 would hold, anything short of tons would be madness unless its a street queen, a 4bt is frackin heavy and has a lot of torque.


Also the sas is the easy part of this project, I hope you realize it is going to take a lot of work and time and headaches and 3 times the money

depends on how you treat your vehicle... if you bag it, no, it's not going to last... the 6bt is what they put in the ram 3500, and it's on 1 ton axles... the 4 bt is effectively 2/3 the size(and power), so fitty axles should be fine... d44 and 8.8... like i said though, if you bag on it, yeah, you can break them... just like i CAN break my d35 and 31 spline 8.8 in my truck if i tried, but honestly, I'M NOT GONNA TRY!

hell, you could even run the d28 for a while (not sure what you've got in your truck) just be gentle with it till you have the money for exactly what you want... build it in stages rather than all at once...

there was a huge influx of people back home that was running 302 HO's infront of 7.5" axles in b2200's the key is 1) not bagging it, and 2) knowing what the limitations are...

the biggest thing for the b22 rear end was not putting bigger tires on it, as that is what's going to allow the stress to build up in the diff... same thing will apply to you with the bt4...

safely, you can run a 460 infront of a 7.5 and d28, provided you're not rock bouncing or driving like an idiot...

Isn't the point of putting in a v8 or deisel so you can do stupid stuff in it?

I understand that completely, it will be my work truck/weekend warrior. I know it will cost quite a bit and that is why i am going to build it in stages like Weezl said.

I am NOT gonna be lowering the truck at all. if anything ill keep it the same height and just cut the fenders a bit. I might just swap in the axles first because that i think the rear is on its way out and honestly i don't see the relevance of rebuilding it when im going to upgrade later. I also know the limitations of the axles and at first im just going to put around to let everything break in. As far as tires I will be putting bigger tires on it but not until i get the axles under there.

Lol yes this is the point but, i won't be until the axles are under it.

First off he meant "bag it" as in beat on it, not lower it.

What size tire do you plan to run. I would say a mild 4bt, 35s or smaller, and a 31 spline 8.8 would work out pretty good (unless you "bag" it).

I'd be worried running a d35 and a mild 4bt on 35s, 33s should be ok. The engine weights about 750 lbs. Maybe a TTB d35 with d44 outers with 35s.

Oh gotcha thanks for the clarification I plan to run about 35's 37's at most.

 

[Bennybooster]

If you want 35's or 37's you need tons unless its an absolute street queen

ton and be done

Oh no sir, it's gonna be all go and some show.lol

that's a good one.

Also would i have to use ford axles because of the room for the transfer case? Or just an axle that is driverside drop?

 

[4x4junkie]

With that 750lb engine in your Reg cab truck, you're not gonna wind up with much over what a Supercab Ranger with the stock 4.0L weighs on the front axle (maybe by 100-200lbs).

The D35 (along with the 8.8") should be fine with that, just don't get too stupid with it is all (such as bouncing over shit with your foot planted to the floor, which applies just the same for the Supercab owners too).
Beyond that, like everyone else has said, the next practical step up is 1-tons (such as from a F-350).

 

[dangerranger83]

Well depends on what side drop the transfercase is when you do it. But as far as having to run ford axles, no. Im running a Jeep D30 in mine now.

 

[86MUDRCJ]

Well if i ran a unit that had pass. side drop wouldn't i have to do something to the floor because the tcase will be to close to the bottom?
