Hey guys had a quick question about regearing on my 2001 5.4 4x4. I am going to be replacing spider gears pretty soon (haven't opened the rear end up yet, just assuming thats what's failed on mine.) IF it is and I do in fact have to replace the spider gears how much more work would it be to re-gear? I am running 35/1250s right now and would like more power. I also do a little pulling with it (atvs and boats.) What gears would be the best bang for the buck (373, 410,456, etc.) I'd like to get a little better gas mileage and just overall better performance (speed,power when pulling,etc.) From what i've read id also have to replace gears up front what would that consist of? Tools/space isn't a problem have a big garage with lift,etc. Thanks in advance

 

I'm in the same boat as you. Same tire size and engine. Looking into 4.10s or 4.30s myself. Subscribing for more info
