Outer Limits 4x4 Board

hi

i have a bj73 and am having problems with it heating up even on big hills on road any ideas wat i should do or wats causing it to heat up like that

and another question wat diff ratio does the bj73 come out with and wat ratio should i run with 35s?
thanks nathan

diff should be 4.1:1 if they're factory, If it was me and I was running the old diesle motor to turn 35's I'd probably go to 4.56:1 diff gears.

Check your fan clutch, mine did the same thing, heated up at 100km up long hills. As soon as I got over them it cooled down again. $12 of clutch fluid and its been perfect

thanks guys ill give that a go and look for some diffs
