What is the centerline of the rear axle in relation to the bumpstop on the bottom of the frame in the picture. Centerline looks to be 37 1/2" from the rear of frame.

Mike,

I think I've seen that info here before and it might be 36", not sure. Maybe someone with knowledge can chime in here.

Come on guys. No one knows the answer? I just read it was 36.5 ". Is this correct?

I'll check mine when I get home. Remember, the rear axle will move in an arc when the suspension is compressed, so the bumpstop will be located farther aft than the centerline of the rear axle when the truck is sitting at ride height.

That measurement of 36.5" might be pretty accurate. That means that the rear axle moves approximately 1" to the rear when the suspension is fully compressed to the bumpstop.

Mine is at 37" with no weight on springs. Centerline will probably move back about a 1/2" with all weight in place. I am using CPP lowering springs and brackets.
