My Bronco 2

4.88 would be better suited to 35's. I'm rockin' 4.56(for the time being...) with a 2.9 and 35's, and it definitely is manageable on the road, but I wish I'd have gone 4.88... ah well, skipping that and up to 5.13! lol
For you, with a 4.0, would likely be good with 4.56 all the way up to a 37" tire... off-road that is. On road, 4.56 and 37's would maybe give ya some grief with an auto. But with 33's, it should be about perfect!

 

[4.0B2]

yeah, i forgot about the 4.56 option...lol.
that's probably the way i should go.

4.56's cost more than 4.10's or 4.88's. that's weird..
how would 4.56's and 33's be on road? i'm just worried about my mpg's dropping down way to much... a lot of my driving is city so the lower gears would turn the tires from a redlight easier.. so would i just need to keep my speed down otherwise? lol

 

[kris97ranger]

my plan was 4.56 with 33s

 

[4.0B2]

my plan was 4.56 with 33s

but how much difference is there from 4.56's to 4.88's?? how much can that .32 change the overall highway speed rpms? it'd be a good bit different than the 3.73's i'm used to tho

 

[kris97ranger]

that i do not know. i just know im running 4.56 (for now) in the samurai on 33s and its perfect. and everyone i asked about my ranger and what i got from the gear after tire change calculator in the tech library was to go to 4.56. i was on 3.73 with 33s and a 4.0 for a good month or 2 b4 i flipped the truck and i was gettign 450km to a tank and still could do brake stands lol

 

[4.0B2]

idk what 450km is... i'm american! lol...

oh...280 miles ok. google told me! that's not bad...

 

[Andres629]

Hey what tranny is in there, A4LD?

 

[Andres629]

I went ahead and took the liberty of determining your engine RPM at 65MPH with different ratios/tire size, based on the final drive ratio of .75 on an A4LD.

33's
RPM@65MPH/4.10 = 2035 RPM
RPM@65MPH/4.56 = 2263 RPM
RPM@65MPH/4.88 = 2422 RPM

35's
RPM@65MPH/4.56 = 2134 RPM
RPM@65MPH/4.88 = 2284 RPM

two thing's conflicting here. big tire's a good mpg's do not often go hand in hand (certainley not in the city) and good ratio for off road isnt necissarly a good ratio for on road (highway) kinda the reasone i'm NOT goin with 5.13's now. i'm gonna run in the ballpark of 4.56 when i get a chance, and lookin at buildin a doubler for offroad. also lookin at the 2.5-4.0 hybrid M5od as it only lowers your 1st and 2nd gear's IIRC.

 

[4.0B2]

yeah. i'm thinking 4.56's, i know i can't have it all.. good mileage and good low gear and good city highway. i'm asking to much i know. but i'm hoping for the best possible mix of the list above. understand? lol.

 

[4.0B2]

just called Rusty's offroad- and a person answered the phone.. not a computer system!

but just their long arms are $460.00
-OR-
i have an offer on arms and stuff being made custom for $800 and that includes the track bar bracket and track bar (as well as the long arms and frame mounts). i think he is gonna weld up the steering to, but i have to buy the johnny joints and heims. which makes me wonder what size joints i really need? what size heims? i've been told 2 different sizes (very different)

kroussinoffroad sent me his measurements of joints but idk where that PM went.. hm...

which joints do y'all recommend? currie? trail-gear's creeper joints?

 

[kris97ranger]

man i missed alot real quick haha but yea my truck had 483'000 km (300'123miles) on it when i rolled it and had maybe 3000km (1800 miles) on it it with the 33s. and that # was consistant. now then again that was always driving normal if i drove like an idiot itd drop to 250km a tank (155 miles)

 

[kroussinoffroad]

i resend soon

 

[kroussinoffroad]

1.25x12 THR flex joint (2.5) is what is installed in the arm.

800 for the done deal is pretty good price,
however if I were to redo it all over I wouldnt change a thing.

 

[4.0B2]

i resend soon

i just looked thru all my PM's from you. i know it was the 2.63" outer. idk what size thread area it was.
