Need your input in my drivetrain upgrade plans...
The goal is to get better crawl than the 42 I have now. I'm also keeping the 4.0 for the next few years. (fingers crossed)
The easy option is to get a Tera 4:1 for the NP231 and call it done. This would give me 62. I can always install 4.88 gears to get 74 and this would be the most I could get out of this setup. Tera ~$900 and I do the work myself, later gears ~$600 with me installing the front ones. Total: $1500 (gulp) and 74 crawl.
The other option I've been thinking is to get an NP435 and a D20 (~$500), the adapters and clutch parts (~$1300) and new driveshafts (~$350). Total: ~$2100 for a 67 crawl and twin stick. Later I can add the 3.15:1 kit if needed for $600 and a 86 crawl. Total: $2700. (gulp and choke)
Now, theoretically I can resell some stuff for how much: good AX-15?, good NP231 w/HD SYE and 2low ?, new TW CV shaft?. Maybe $1000 top?
Also, I don't know exaclty what I'm looking at as far as the installation of this setup since there are used parts involved. I'd need new clutch ext. slave setup and cross member fabbed, maybe tranny or tcase rebuild before install.
On top of all this right now I only wheel maybe 4-5 times a year but I move up in grades every time. And I have to drive to the trails. I'm planning to get a tow rig and trailer in the next few years so I can drive to more events in comfort plus I'm hardly legal any more.
I'm kind of leaning towards going the easy route as long as that setup would hold up for the next few years. I'm running 36" TSLs, 8.8 rear, D30 front and I'm easy on the pedal. Sorry for the long post, just ignore it if it bothers you. I'm just thinking out loud here. Appriciate your opinons though. Thanks.
