Hi every one I'm putting together a rig that has a 1997 fj80 frame and running gear My question is about the front axle, is it strong enough? I have a 6 liter ls engine around 375 to 400 hp with a 4l80 trans I'm also using the 80s transfer case with a part time kit and a low range gear set. My plan is to install 5.28 gears with RCV axles. I will be running 40 12.50 17 tires. our plan is to tow this with our rv and use it around the country so we are building it to do many different things. but places like Moab are high on the list so we want to make sure its worthy, thank you for any advice
