i recently purchased a 82 bj60 with the 3b and stock 4 speed. it also has 35's and the stock diff gears. I am going to purchase new gears asap but am unsure which ones to get. i did search but found that most guys with 35s and diff gears also have the turbo motor. the truck is going to be my daily but also lots of weekend wheeling. :beer:

4.56's.

You dont have an overdrive AND you do have a diesel.

Hell, Ive got an HJ60 with a 1HZ in it and 37's and Im only going 4.56's.

thanks for the quick response. thats what i got in my searching but couldn't find anything that directly related to my motor
 
Best place to buy gears.

Gears and such

You still may be running hot with that set up. You might think about an H55.

wayne here,
find a H55F asap to start with even before the gears, put your guts from the 4 speed case into the 5 speed housing and then a turbo, there is many cheap home built options to choose from till you can do it right or if you are lucky then you will like the setup you install and stick with it.
finally i would suggest the factory 4.11 gears since they are easier to find if one set grenades where as the after market set needs setting up on your center unit and some of the gear sets actually need the older carrier to be installed...
this is just some ramblings from a guy that has played for a while with these trucks...
cheers
 
thanks for the advice :) Is the H55 or h55f easy to find? i live in Vancouver, BC so i'm dealing with cdn. funds. but i don't mind shipping to Lynden if i need to buy down south
 
I don't think you can get a H55F for the 3B new anymore. Best bet is to find a BJ60 with the 5 speed or source one used. If everything else is running well with the truck I would go with the 4.56's. I've got those in my FJ62 with 32" tires. Definitely overkill but it makes jutting in and out of city traffic really nice. And in a stop light race I can beat anything for the first 3 metres.
How does it drive the way it is? Do you go off road alot? Are the axles in need of a rebuild? How is the motor? You could get a 13BT with 5 speed and transfer case. The possibilities are endless. That's what I love and hate about cruisers.
 
if you wheel it, go with the 488's. i run a 5spd and 35's (bfg so a little small) and still need more gear off road, but it's better than 370's. i ran stock gears and no turbo for years with 35's, it sucked, but i still got around.

as far as highway goes, the 488's are fine with the 5spd and 35's. how fast do you want to go in a wagon on 35's? really, anything over 100kms is starting to get a little scary.

all i can say is, is there such a thing as having too much gear? if you wheel it you'll still want more even with 529's.

like stone said you should be able to find a good used h55 around in van in the 1000-1500 range depending on condition. maybe less.

can any of you vancouver cruiser heads help this guy out? i'd offer my spare up for sale.... but then i would'nt have a spare now would i?

that's my 2 cents

Wayne here:
yes there is such a thing as too much gearing. you set it up for the wheeling you want to do. if you can not get the wheel spin up then mud is deadly. if you can not get the momentum up then ice covered hills are undoable.
if you are rock crawling go for it, if you are doing cutlines and average off roading then 4.56 is the lowest i recommend, i run 4.11s in all my trucks and have not come across something in the mountains that needed lower in 23 years of trail riding.
each to their own but be carefull of the recommendations. it is someone elses money you are spending.
cheers
 
After having tried 3.70, 4.11, 4.88's & 4.56's in my 70, I agree w/ Wayne....you can have too much gearing. I have both the H55 & Marks Tcase gears with the .92 overdrive and I still found 4.88's to be too low. I drove from Sacramento to Moab in 2002 and it took me 18hrs because I could'nt go faster than 100kph(this is normally about a 14hr drive). I'm currently running 4.56's & the truck is now dialed pretty close to factory specs (4.56 + H55 + .92 Tcase + 35 MTR's)....it does well on hills, cruises 120kph at about 2,500 PRM and still has a decent crawl ratio. Before you do anything, use the TLCA RPM tables http://www.tlca.org/trails/techxchg/rpmtbls/index.html#Define_The_Gearing_Yourself and define your gearing....then ask yourself how you'll be using the truck, how much pavement vs. trail will it see and go from there. Gearing a 3B is MUCH different than anything else...that little motor is working very hard if you're trying to do a long highway trip and hold 2,900 RPM so you can keep up a decent speed....
 
I just recently purchased and 82 bj60. It revs at almost 3000rpm at 100kph. I'm assuming this is normal with 235/75/15 tires and stock gears (i think). I came back from a road trip and got 27mpg at rev's that high. I was pretty impressed.

Rev's are high with the stock 4 speed but drop in an H55 and the rev's drop to about 2400 in the same situation.
 
well i'm not going to start a pissing match, but 488 5spd and 35's are not too low in my opinion. they are not low enough.

depends on how you want to set up your truck. i wheel but i drive it every day.

it's a lifted f#@#ing cruiser and it's slow on the highway. in comparison to most other cars.

dieselbigot: i drove from victoria to loon lake last year in a fully loaded bj60 with three adults two large dogs and all the canadian beer and gear (and parts, and recovery gear) one might need for a trip in the mountains, and i still averaged about 75mph on the I5 getting there. but i don't drive like my grama. 35's 488 5 spd and a stock split case. oh and turbo.....

if you are going to mostly drive it on the road, dont even bother with gears, get some snake blinder polish and be done with it. bling bling!

and if any one has any more of someone else's money for me to spend... send it awwwn up!
