2004 Rubicon Parts for a 99 TJ

I have access to a wrecked/totaled 2004 Rubicon. The serviceable parts I can get are the front / rear axels (D44 w/ lockers and I believe 4.11 gears) and the coil springs/shocks. I currently have a 99 TJ with a Dana 44 rear and Dana 30 front with 3.73 gears. I also have a 2.25 BB and 32X11.50 BFG MTs.

Can I get the Rubi parts and sucessfully instal them on my TJ? I was told the Rubi coils would basically equal my current 2.25 BB so could i still use my BB ontop of the Rubi coils?

I am concerned about the 4.11 gears as my current gears and 3spd auto rack up the RPMs on the interstate (2900-3100 RPMs at 75 MPH), so I know the 4.11 would probably be even higher. Then again I may upgrade to 33X12.50s so the 4.11 would be an even better gear ratio for those size tires.

Any advice or potential problems that I might need to be aware of?

Thanks,

everything should transfer across, can you get the t-case a well as that would give you a 4-1. Your rpm's will go up as well but if you are going to 33's cool or even 34 might be a good choice.

your lucky to have this opportunity.

the axles will bolt in.

if you already have the 2.25 BB then why bother with the rubi springs?
do you have aftermarket extended shocks with your current BB?

PM'd ya too

The axles are a direct swap, the locker wiring isn't that difficult and there are a couple writeups to show exactly how it's done. To repeat what others have said, if you can get the 241 transfer case don't pass it up, either use it or resell it but it's worth some cash and it'll save you money in the future because you won't need a SYE like you will on your stock 231. Also, if you can get the locker switch that's on the dash in the Jeep, even if you don't use it it's good to have along with the air pumps which are bolted together on top of the t-case skid on the driver's side of the Jeep.
