Spacecab Body Drop????

I have read in 2 different places about how much it takes to lay rocker. One place said it is only a 2" bd and the other said 3"s. Can someone help me out??? Thanks

i've got my frame out from under mine right now so i can measure the body mounts to see how far it is to the rocker from them...or i can measure to the pinch or door for you

its 80mm watever that converts to in inchs i measured from the ground to the sill where it turns to go under the cab.

If the frame is laying flat front to back it only takes a 2" bodydrop.The one's you see bodydropped more than 2" don't lay in the front,so they drop the body more to make them lay flat.I've done several Isuzu's,and had a spacecab before myself.

well mine lays all teh way out the ft. cross member and the full frame but the ft looks to me higher than the back of the cab it sounds funnie but it looks like i am going to have to bd the ft 4 1/2inches and the rear 4 inches

this is exactly correct, I have a isuzu parts truck I am thinking of bagging and selling and the first thing I will do is z the frame.

is it necessary to z the front to get it to ly completly??

no but theres more to do if u dont z, if i were to do another one id definately go the z'ed.

All my Spacecab needed was a 2" and fold the pinch under.

chris if this is the same space cab i saw z that thing to get the oil pan off the ground but last i checked it was 2 1/2" to the pinch and 3 1/2" to flat rocker
