I was searching through this forum and found not much info on the oh so famous 2.5 ton axle. I was wondering what the specs are for those, tips and tricks to maintaining them, pictures what do you have them under, if they are legal for street use and stuff like that. Hopefully this can be come a catch all for Rockwell axle info.

 

no legal issues of running them on the street, but they suck. they are extremely heavy and it costs a ton of $$$ to get proper brakes on them. Offroad they are cool and they are strong but not recommended for a DD.

 

For street use, gota go with 4 wheel disc conversion, they have anywhere from 6.17-6.67 gears, so you need atlesast a 44" or bigger tire so rpm's aren't threw the roof. Easy to maintain being a militry axle and not alot to them.

 

Does any body have rockwell's? pics, specs, issues, wreackage? show em if you gotem

 

chuckstrucks.net go to fourm, everthing you need/want to know about toyota axles all the way up to full blown monter truck plantary axles, etc..

 

you could go on pirate4x4 too but lube up your cornhole before you hit the post button.

 

with disc brakes they do not weigh much more than a outfitted 1ton axle and are way stronger and cheaper than an built 1ton axle..chucks truck forum check it out all the info you will need hope that helps..

 

everything you need to know...... Link's to rockwell question's and info... - Pirate4x4.Com Bulletin Board

 

so far so good. but again does anyone have them on their truck? What did you use for suspension setup? 4 link and coils, leaf springs, or air spring? remember its not only for me but for anyone thinking about doing this. BTW Overson engineering has tons of stuff for rockwell axles... including new gear ratio sets!

 

Tons of mud trucks run 2.5 tons..they have their ups and downs
Gm's are cheaper but rockwells are stronger
Cummins on the rocks..Lee's 12v

I know a few people with them on the street
as far as gearing takeout rockwells come with 6.72:1
Suspension can be set up leaf sprung or coils it just depends on what you want and how deep your pockets are
