I have a 2000 F-150 triton 4x4 offroad which I'm planning on switching my 26570r17 (7.5" rims) to a 28575r16 and a 2-3" body lift.

Should I get new shocks? If so, how do I know what size to get? Does anyone have recommendations?

Thnx

 

I did the same tire swap on my old 97 4X4 that you are going to do. A body lift is not required for those tires. A couple cranks of the torsion bars and things look good. New shocks aren't required since you aren't changing the suspension, but I think everyone will agree a good set of performance shocks would be a nice upgrade. If you are going ahead with a body lift, the body roll of the truck will be greatly increased and new shocks could greatly help control that. I had Edelbrocks on mine and I thought my truck performed rather well, especially after the addition of a swaybar.
