Hey FTE, I just bought a 91 F-150 standard cab with short bed. Everything is stock with 4.9l I6 and 4 speed with granny low. I love this truck already. It's a tank and would be unstoppable with some traction.

Starting with tires, whats the largest I can stuff under it? A little fender cutting is okay. I was thinking 33x10.5x15 mounted on 15x8 rims.

Does anyone know of a good rear leaf helper spring or a mod that can keep my truck from bottoming with a full load of Oak? Maybe F250 leafs or a custom leaf pack?

Thanks for the help.

 

Is it 2 or 4 wheel drive?

 

It's a 4x4.

 

Hey danman282, have you considered air bags to level out the rear of your truck when under a load? We offer a 59501 kit that is designed for your 91 F150 4WD. You can learn more about the system here: Ride Control; Leaf Spring Leveling Kit. Let me know if you have additional questions and I'd be glad to help.
