[MTNRAT]

At 80 mph, rpms are 3000, with 4.88s, and 315 mtrs.

What is the OE pinion ratio?

I'm running stock axles on 33's and it is fine for what we do. I'd love to stuff 35's under there though. How much lift are you running Mabrodis?

I believe OEM is 4.11.

OEM is 4.10:1

The only times I wish I had 4:88's is when I'm following someone down a steep hill.. like a stock geared BJ70- not only does his exhaust stink, but he can go downhill for a mile and never touch his brakes, just keeps chugging on down. I'll wait until he's almost out of sight, then proceed down the hill in L and L, and within a minute or two I'm right back on his ass and have to hit the brakes again.

Speed off the line isn't important to me, but I did notice a drop when I went to 295 75's. I do like cruising at 65mph and about 2200 rpm's though, then again I don't have any speedo correction so that's probably closer to 68 or 69 mph, 2200 rpm's.
