I have a 2001 F150 Supercrew, 4.6L v-8 with 4in lift kit and 35" tires. I am in the near future going to have to replace my gears on my truck. Last year I started hearing a popping noise when I would turn left so I took it to an automotive repair shop and found out that my gears had eaten themselves. So I had to shell out $2000 to have my rear end rebuilt. Yesterday I was making a left hand turn and heard the popping noise again. With all this said...I would like an opinion on what gear ratio I need to put in.

 

4.56-4.88

 

4.56 if you do much city driving. If you do almost all highway then possibly 4.10. I'm getting 35s soon and I'm getting 4.56. I would think 4.88 would be a little much

 

4.88's are not a bit much with a 4.6, it needs all the help it can get, there's not much low end torque to begin with. If you had a 5.4, that would be a different story.

 

True. I was thinking in terms of my truck. I have a 5.4

 

I will let you know how my 4.56's are, they will be done thursday...

 

I picked up my truck today, I must say wow...I am extremely impressed, it is like stock if not even better, seriously....If you have the money, buy them... 4.56 all the way....

 

My 4.56s are getting put in right now I'm also in the process of putting on a 6 inch lift and I'll be getting 35s

 

What did u end up paying total?

 

Installation with G2 Rear diff cover, 5 extra quarts of oil to change after 1000 miles totalled $1705 out the door with tax...

 

What website is the best to order spider gears and ratio gears the cheapest?
