I am curious to know what the actual differences are between a lighning chassis and a regular f150 chassis. Every where it just said they were "heavy duty"
Thanks,
Sean
The main difference is the thickness of the rails. The L rails were formed from thicker steel. I think there are also some stiffening braces that the std. F-150 didn't get, but I don't remember for sure.

Confuscious say "Man who have no use for jackstand have promising career as jackstand".
They're the same thickness as the 4x4 F-150's. The L frames also have plates welded at the rear gussets; just above the axle tubes.
