gear selection

[kb9qdi]

I have a HP30 and 8.8 in the TJ with the 4.0L and 6spd. I run 36" SX's on beadlocks offroad, and 35" BFG AT's on road. I have 4.10 gears, If not for the 6spd. with the lower first gear it would not be good off-road, even in 4LO. Honestly I liked the accelleration on the street better with 4.10s and 32" AT's. I am re-gearing mine to 4.88, much better for both on and offroad. Remember Jeep put 4.10s with 31's on the factory Rubicon with a 4:1 TC.

Go 4.88 you will be MUCH happier all around.

Ditto.....8.8 with 4.88's/D30 and a 6 speed. I'm at 2700 rpms or so at 65mph in 6th. Gobs of passing/hill power. Best $ I ever spent

I DD mine 40 miles a day getting 12-14 mpg depending on my foot. Don't fear the gear......you'll love it!

4.0 5 speed? 4.88s for sure, gives you growning room too
