Hey Everyone,
I needed to post this and see if people who've done it can clear things up for me..... I've searched and read for two days now and this area really seems to have many variables. So, I'll give you all the info I have and the country I'm in and help me see if 4.88 is the way to go.
'99, 3.4L Auto with E-Locker (4.30, I'm 99.9999% Sure. Did the Tire turn test with 20 rotations, and reading lots of threads).
Everyday weight with 1/2 tank of gas: 4672 (It will get heavier)
Camping weight with people and gear: ~5500
Tires: 255-85/16 (narrow 33") - May go wider, but doubt ever 35"
Altitude: 0-2000' so far
Daily Driver - But have Company Van so it parks in the shop 80% of the week.
Weekends - Around Town on errands
Trips - We have no freeways (so to speak). All highway 45 - 65 mpg. I hit 75 if I pass someone only.
Offroad - Mountain roads, Trails. Now I have winch so I will branch out more.
Current Driving Conditions.
I drive with the O/D on most all times. Whenever I go up anything more then a basic hill I'll take it out of O/D so it doesn't bog down and to save the temps. Most vehicles will catch up to me easily unless I push it and it downshifts. Going into the pass between here and Anchorage I have to pay attention to driving a lot so I don't get the constant upshift downshift going on.
I don't really care about gas mileage. It is what it is. But I've built this to EXPLORE. So that means long trips, Highway and Dirt, Trails, and Off Road. No Mud Bogging, No Rock Climbing.
-----------------------
Depending on the thread, I lean towards the 4.88, but then on another it seems like the 5.27 is the way to go.... I've read several places that the Auto with 5.27 is like the 5 speed with 4.88... To be honest, I'm right at about 60% sure that 4.88 is the way to go for me (mostly due to tire size), but then I start thinking about current and future weight, and I never drive this over 70 mph under normal driving conditions (as stated, only if I pass which isn't very often) so then I start thinking about 5.27.
What I would hope to do is get prebuilt package from ECGS and swap them out. Main factor will be shipping costs. Even with shipping I would think that is cheaper then having a local shop upgrade my current setup.. I've never dealt with a local axel \ gear shop here so I have no idea if I can trust them. I'm just in the research mode right now. This wouldn't happen even this year. But with upgrades like this, I like to know what the hell I'm doing. I'm super OCD that way.
Can I get people who have travels this same path give me their advise? Much appreciated!!! Please ask any questions to help confirm the right course of action.
