Hello and thanks in advance for any help!!
Before anyone mentions it, I do want to stick with my Dana 30 and Dana 35. I'm not running big tires or power.
*I tend to blabber, so you can skip to the TL;DR now if you want lol*
I currently have my first TJ (third Jeep-XJ convert ).
PO took immaculate care of it and, mechanically, it is fantastic. Except it has the stock 3.07 gearing with the LP Dana 30/Dana 35 combo. No abs.
Anyway, the PO put brand new 32" Duratracs on it, which are perfect for my needs (road driving to work and then light to semi moderate wheeling a few times a year), so I want to keep the tires.
BUT, the 3.07s are a MASSIVE pain. My short commute is on the interstate for about 20 miles a day. Plus the 3.07s are a complete dog in city driving. The only time I find the gearing adequate is on the trails in 4Lo, but that's different.
My dad and a friend both have manual 4.0 TJs, 32s ans 33s, and they used 4.10 gearing and I really like the way it feels. Much easier to live with. **And they definitely get better mpg than me**
Ok, so my list of parts (ignoring any possibility of adding trutrac, LSD, or any lockers for the sake of this conversation):
Here's what I've ordered so far. If someone could confirm that I'm on the right track or point out anything else I'll need for the install (I'm having someone do it. I can do a lot of stuff, but gears are not something I'm comfortable with).
Some parts don't match brands, because I shopped around for the best prices.
Dana 30:
1. New Spicer carrier since I have the 3.07 carrier.
2. 4.10 ring and pinion gears.
3. RC Dana 30 master install kit.
Dana 35:
1. New Yukon carrier since I have the 3.07 carrier.
2. 4.10 ring and pinion gears.
3. RC Dana 35 master install kit.
*Tl;DR: 99 TJ 4.0 5spd going from stock 3.07s to 4.10s. Halp with list of parts I'll need. Thanks
Thanks in advance for the help! I'm a gearing noob. This is the first time I've had to change them.*
** have gone through and replaced and/or upgraded any and all fluids, intake/exhaust/ignition/fuel delivery components, so I know it is all in good working order.**
