I have a 08 f-250 4X4 and I looking at swapping my 3.73's out for some 4.30's. I have a buddy that will do the swap so is there a kit out there of everything I need as parts goes? Thanks.

 

I would say check out randys ring and pinion

 

Do they have a website? Is that the name of the company?

 

Randy's Ring & Pinion. The Differential Experts. Auto Parts & Services.
They have been in business forever

I would recommend making sure your friend knows what he is doing I went down that road and had to have it done again a few weeks later it was a very expensive learning curve for me for the money you save is not always a good deal.

 

Well he is tech at a ford dealership so I sure hope he knows what he is doing. He has been there for over 20 years. Thanks for the info.

 

No Problem Just dont want to see someone get burned Have a good one and good luck.

 

bronco graveyard sells the complete kits front and rear for really good prices. here's the link:
1999-2008 Super Duty - Chassis - F350 Gear Kits

 

Diddo. Had real good luck with them and if you have a problem they will do everything they can to help you out.

 

Thanks for the website. That is exactly what I was looking for. Now why is the 4.30 kit 120 bucks more then the 4.56 kit?

my guess would be because it is a taller gear than the 4.56. call them up, maybe they will be able to make you a deal

 

Hell I might go with 4.56 gears. I think they will perform better.

 

Probably the 4.56 is more popular than the 4.30. Try to get an install kit with Timken bearings.

 

Why those bearings?

 

Quality bearings, made by a company thats been around forever. I trust them. A differential is not a place to experiment with bearing mfg. co.
