Other info:
The 231 has a driver's side front output and centerline rear output. The NP231 features two ranges; a low range gear that is a respectable 2.72-to-1 (the lowest of all the Jeep transfer cases with the exception of the NP241OR) and a direct-drive in high range. It features three modes; two-wheel-drive, four-wheel-drive and neutral - for a factory combination of 2H, 4H, N, 4L. Aftermarket modifications allow for the addition of a 2 Low position.

The standard 231 weighs about 70 lbs. HD 231's can weigh up to 80 lbs.

The standard duty OEM 231 transfer cases are capable of transferring from 1600 to 1900 ft. lbs of torque (as claimed by NVG - actual experience puts this number quite a bit higher).
