I'm new to this site so if I make mistakes please forgive. My truck is a 2009 f250 6.8. Ive got intake, dual 4" exhaust w/6" AR-15 tips, 5 star tuning, 8" lift running ONLY toyo muds. Getting ready to reggae it now and looking for real world experience. Anyone have a re-geared 3v v10 on 37" tires?

 

I don't have a v10, I have the 6.2. I'm planning on running 37's and I'm going 4.88's. This will get you very close to a 4.10/4.30 with a small factory tire combination. If you don't tow or tow light, you could get away with 4.56. This will be a little lower geared than a 3.73 truck, but you have a lot of extra weight to turn. If you tow heavy a lot(which I doubt with an 8" lift), you could certainly justify 5.13's, but not if this is mostly a daily commuter.

 

Thanks. I tow a bit bit nothing heavy. 25' enclosed with toys and a 12' work trailer. I've been leaning towards the 4:88 so that's a good confirmation. Thank you
