ok so i want to put some 4.56's out back and i dont use 4x4 so i am not 100% concerned about doing the front diff in a ford racing gear, but ford sells the gear for our trucks rear end...but not the front....where to get the front end, what are you guys running for front gears....and i guess as long as i dont engage 4x4 id be fine but if a kid or a buddy hit it i wouldnt want to risk damage...

I only have a 2WD, but I have Yukon 4.56's in my truck.

how are they compared to stock...as far as whine...not performance....


god i wish i was 2wd

If you have it, go with it. Change both or none. If you gear the rear different than the front your transfer case will explode if engaged.

grenading transfer cases are bad, mmkay.

man you guys wanting 456 gear... shott...shoot whatever word is... pretty tall gear...the last time i had 456 top end sucked but coming off the line and getting there was awesome..

blackbetty

agreed...only used it once in the mountains however i figure im going to do both but i just want to do some research on who to buy seeing as ford doesnt make a front diff gear in 4.56

I don't notice any whine at all with them. I went with the 4.56's because of my lift and bigger tires so that I could regain the power I lost. It's not really needed unless you're adding 35's or bigger, heck even with 35's most guys don't regear.

I had 4.56s in the Ranger with 33's. GREAT gear for larger tires. I used Ford Motorsports so they were an OEM cut gear. No whine. I put them in myself so I know the job was done right. Yukon is an OEM cut gear. Richmond is not. Richmonds will more than likely whine. Don't forget the install kits.. All the bearings, shims and crap you need to install gears. Don't do just the back, not with that big of a jump. One gear size would not hurt ya if you did not lock it in on pavement. That much is too much.

not lifting it...going to do it for out of the hole performance...the 4x4 is only needed when i go up to the mountains to snow board or when im back home in new england...

so yukons are the way to go?

anyone got any links on where to get em and exactly whats needed...never did gears before...

also wat does it usually run for install prices?
