I added 31 inch tires and a 3 inch rear add a leaf lift. This did not noticeably affect power. Does anyone know if a 3 inch front spindle lift affects power on the 3.0s? I’m not concerned too much about MPGs, but any less power on the highway would suck!

Got a 2003, xlt, 3.0 ranger. Forest green. No considerable rust. She’s a beauty despite the slowness so I still love her haha.

Thanks!

 

The 31" tires will effect power to a degree but the 3" lift will not. However, the 3" lift will increase aerodynamic drag and will be slower with headwinds and will drop MPG at higher speeds.

 

Exactly the answer I was looking for. Thank you.

 

Putting larger tires on your truck changes how the speedo reads. If your speedo says 60mph, it is actually going faster. It will also affect the odometer and tripometer naturally, you'll being more miles than what it says so it will give you a false mpg.

 

Ive had the 31s for a while. Ive noticed that the speedo reads about right still up to ~45 mph. After that it reads about 5 MPH slow (according to GPS). I've given up trying to figure out what my MPG is, since despite having a 17 gallon gas tank I've definitely topped off more than that. I just go by the average "trip" mile counter reading per tank. In the winter, 200 miles city/highway is typical. In the summer 250 is normal if I recall correct. Ive gotten up to 275/300 doing mostly highway. Since getting the tires, that hasn't changed too too much.
