Please go make yourself a signature. But judging by all your million other threads you've posted, you've got a 98+ 4x4(2004-2005 Fx4 if I recall correctly). Correct gearing for 35's would be 4.88. It's the deepest you can go on the front axle...so your sorta stuck to 4.88 being the deepest.
For 35's: 5.13 vs 4.88.....well.....4.88 would be more drivable in all around conditions(city/highway...very good mix of both). 5.13 would be a great crawler when put into low, a fun fun fun truck around town. Would totally suck on the freeway.....4,000 rpms or so at 70mph in top gear. Still stuck with 4.88 on the front axle being it's the deepest you can go.
'01 XLT disguised as a '03 Fx4 Level II.
