4.11 are a little diffrent than the 4.10's though right?
37 / 9 ring and pinion vs41 / 10 ring and pinionWith the extra transfer gear, you don't need to regear the differentials for a lower crawl ratio.Plus they are probably out of money after spending it on the 2nd transfer case.
My thoughts on this are tho, for serious rock crawlers (who should be running 1ton axles or 2.5s or mogs) but for those running their toyota axles hard, they SHOULD be running the LOWEST axle ratio they can, I hear stories of blown driveshafts, blown transfer cases and bad clutches. when a 5.71 diff (see ZUKs artical at gearinstalls.com before you say they are weak) is used in a toyota axle, it puts the actual WORK at the axles and out, marlin sells thicker flanges, chromoly outputs, thicker outputs. having the LOWEST RATIO AVAILABLE would make all those parts see more RPM and less TORQUE.
you will NEED less torque to provide the same final output
