5.13s VS 5.14s

[dangerous_rangerous]

Okay so I know the obvious difference in the two sets of gears but my question is.... I have 5.13's for my d44 front already and I want to drive my truck daily, in the case I would need 4wd say come winter time on the asphalt/hard surfaces would it hurt to drive in 4wd with 5.13's up front an 5.14's out back (9" ford)? Reason I ask is I have a buddy with new Richmond 5.14's for $60 for the rear and I already have the 5.13.s for the front. Any input would be greatly appreciated.

You will be perfectly fine, that difference is barely anything (having a little less air in a couple tires would probably be worse) A lot of vehicles come stock with a slight difference in gear ratio (4.10 front and 4.11 rear for example) Nothing at all to be worried about.

.05 is the max tolerance for gear difference.

.05 is the max tolerance for gear difference.

So does this mean they would be fine? Need a definite yes or no. Kind of confused between the 2 answers i got.

^Thats your answer.

awesome thanks guys!

well if .05 is the max tolerance for gear difference, and 5.14 minus 5.13 = .01

......yes you're good

you'll have no problems,
plus in winter, the snow will allow slippage between the front and rear.
The only time I'd see a problem is if you were in 4wd on dry pavement, it might bind up, but you'd have no reason to be in 4wd in dry pavement unless you just forgot to take it out.
I've seen people run 4.88/4.86 gears with no probs.

Yeah Randy's Ring and Pinion tech guy said the 5.38/5.42 combo for the d44/9" will work good, so I guess the .05 tolerance still applies.

correct me if I'm wrong.... I know this gearing is typical, i'm running 4.09's up front and 4.11 in rear. However, I always figured the reason for the front to be higher geared was so that it pulls the truck rather than giving the rear a chance to push and cause driveablity problems when in 4.... Is this true, or have you ever seen or heard of gear combos where he front is lower geared?

 

[slammer67]

that's true, lower number is a higher gear, so you'd have higher gears (slighty) in the front.

Mud racers do it all the time - put higher gears in the front to get more wheel speed, they say it helps keep the truck going straight and keeps the back end from wanting to pass up the front.

I was told that there is a difference in the gears to make up the difference from the transfer case. When I bought my 4.56 gears for my truck the front was slightly different

I've seen 3.54 front with 3.50 rear in older Fords.

yep they do this so that when your in 4wd they front wheels will be pulling therefore you can still steer. wheas if your rear was pushing faster than your front is spinning you will have trouble steering.
