Rollpan=truck lifted in rear ?

If I put a steel rollpan on my truck will it jack the back of my truck up? If I do this I might just throw the spare in the bed. Comments please!!!

Yeah mine lifted about half an inch up. or I could tell it moved up a tad at least

Thanx, I figured it would

i could tell a ig difference, with the spare and bumper weight gone it made my 2 inch drop shackles disappear... sucks but could prob be helped by battery relocation/spare remounting or overload spring removal...
