I've asked this question many times to local 4x4 shops and always get different answers...So I'm hoping someone has a similar setup as me and can help me.

I have a 1989 F150 Reg cab... With 6" suspension lift and 3" body lift with 35s...and wanting to switch to 37s.

Would I be able to run 37s on my lift set up?

Thanks. All help will be GREATLY appreciated!

 

Idk about the body lift but with a 9" lift you can. My son's 94 has a 9" lift and he's on 37" military tires.

 

Yes, but I don't recommend going over 35s on a d44 ttb. Also you need to regear.

 

will you? Yes they will fit fine I run 36's on 6".... Only thing is you may rub but that will probably depend on tire width, rim width and back spacing ect.

 

With 9" you can fit 39.5" trust me ...ive seen me do it lol i have 11" now and yes still on my TTB with 4.88s and yes i wheel and play in the mud....still no problems......but to answer your question YES 37s will look just right under there too ...
