yeah, the V8 in these things are beef- but like micheal said and Richards knows too- the engines are very costly to replace- just dont over heat it- but the power is there and the torqe is too- the trany these things are running and have a gear split it 02' i think from 4 speed to 5 with the 4 speed tranys just needing to be reflashed to obtain the 5th gear- crazy how jeep hides options. they are much stronger that the tranys int he rubi- RE45- handles a ton of torqe - the tcase is optional at the 242 quadra-trac and the 247 quadra-drive, both good but each are load with diffrent packages. the only thing i found to be bad with these are when i picked up a OR241 case with plans to swap it in the WJ only to find out the output shaft on the RE45s are really short and for people of swap in the NP231 cases in have to tare into the cases and swap input shafts btween each other, and with the OR241 have a complete shaft /unswapable, i throw it in the trash. but tons of options on the other cases and Advanced Adaptors makes extended input shafts for the D300 and NP231 -
