??? Gear Ratio conflict ???

[77 Mud Buddy]

I just picked up a set of 4.88 gears for my D44 and 14B FF (10.5" ring gear) After closer inspection I noticed that the D44 gears claim to be 4.89's and the 14B is 4.88. Is this .01:1 difference going to be a big problem.

This is what I think: (Note: I have a NP203 transfer) on the street is a no brainer, I'll keep my front hubs unlocked and my tranfer in "Lock" on the street and I'll be okay. As for off road, with my hubs locked in, as long as I use the NP203's "LOCK" position, transfer differential not engaged, only when I need it i'll be good to go. What do y'all think!

.01 will not be enough to make a difference, 4.10 gears are commonly available in 4.09, 4.10 and 4.11 depending on what axle; yet still usually called four-ten gears /forums/images/graemlins/thumb.gif

The difference is 0.2%... your tire's overall circumference varies more than that. Don't worry about it.

Nope, it won't be a problem. The gears in my D44 front are 45/11 = 4.09:1 and the 14BFF are 41/10 = 4.10:1.

These axles were both under the same truck, so it came from the factory that way. /forums/images/graemlins/thumb.gif

count the number of ring gear teeth and divide by the pinion gear teath. That is the true gear ratio.

agreed... a .01 diff is no problemo...

Cool digidy,
I have not delt with gears much yet so I just wanted to make sure. Thanks for the info y'all.

203s have a diff in them therefore it really shouldn't matter

 

[77 Mud Buddy]

Yup, that is kind of why I brought it up! My consern was when it is put into the "LOCK" position, it then locks up the internal diff. I didnt know if useing it in the "LOCKED" position would cause any problems with the mentioned gear difference.

Thanks for input though!

<font color="green"> 1% difference is fine for the street, 2% is fine for offroad. So you would be fine even with a .04 difference in ratios. /forums/images/graemlins/thumb.gif </font>
