4.10 speedo corrector gear - who got the best price?

(Click here to view the original thread with full colors/images)

Posted by: AbrahamLincoln

need one of these gears to adjust my speedo. where should i go? supercoupe has a nice number - steeda wants 15.95, supercoupe 18.95 - they'll match prices though which is cool.

I just got mine from Max at 5 star Ford for like $6 shipped.

Posted by: AbrahamLincoln

new? how do i get a hold of him?

Posted by: mrzeee

The gear for the 4:10's is the 21 tooth DOOZ-17271-B. Is this the one I sold you K9?? And that gets you close. right. they are now priced at 2.00 retail and cost lvc 1.50 plus frt.

That's not the correct gear for 4.10s. You need a 23 tooth, which is a Jeep part.

Your best bet would be to run a speed-cal instead of those flimsy speedo gears.

Posted by: mrzeee

m maker you are correct. Like you say the 23 tooth is a very flimsy gear and wears quickly. And they are about 13.00 each. The best way is the speed cal but you will not get one of those for 6.00!! and ford racing dont have them anymore.

yea but steeda does? im lost what you guys are talking about though....

steeda lists 392-STE-17271-J
Automatic 8-Tooth 4.10 Ratio / Black 23 Speedo Gear

it says to use this for cars between 90 - 98 - im assuming we have 8 tooth or is it 7 tooth?

max 6 bucks shipped, i need one asap

Posted by: AbrahamLincoln

wtf jeep part? whats the part number?

Posted by: Moes8

you do not want a 23 tooth, the extra teeth make it so weak it will disinegrate quckly,,or so i have heard,you will have to replace these often,

a 17 tooth and a 23 tooth are exactly the same size so with every additional tooth the gear gets weaker, over 20-21 it really gets flimsy.

Posted by: Markviiiedrea

I bought the one from max last year and it is a 21 tooth, it corrects for 3.73 but is only between 4-7 mph over what is right and last allot longer then a 23 tooth.

The way I drive I'm surprised that I don't destroy this one too. Plus you cant beat 3 bucks and there easy to do, just lift the drivers side and use a 10 mil to get the sensor out witch is on the tail shaft of the transmission housing. 10 –15 minutes tops.

Posted by: AbrahamLincoln

whats the part number, is this a jeep part for 3 bucks??? is this something i can go buy from a parts store or dealer?

Posted by: 98LSC32V

Keep in mind you don't need a speedo gear if you have a gen 2.

Posted by: AbrahamLincoln

i have a gen 1? can you get 3.73 speedo corrector gears from the dealer? didnt the explorer v8 come with these gears?

Posted by: 98LSC32V

Yes you can get the 3.73 gear from the dealer.

Posted by: AbrahamLincoln

please elaborate.... im looking to do gears eventually on my gen2 and i dont wanna have any probs (i got some 3.73's built in a pumpkin, just gotta swap it in)

Posted by: kustomizingkid

With a gen 2 an SCT can fix the speedo, where on a gen 1 it can't, really an obd1 vs obd 2 thing.

Posted by: Markviiiedrea

Chicken, all you need is a 21 tooth from max.

Posted by: AbrahamLincoln

isnt that the same one 21 tooth you can get from the dealer that I just posted

i have a gen 1 with 4.10's installed where can i get the corrector gear for this, i read that you can get the 3.73 from the the dealer and there not as flimsly at the 23 tooth gear that ive read that breaks a lot.

i would like the dealer part number, or confirmation on what i posted if thats right.

i did the math on the t-bird site that has a calculator and it calculates that i need 21.8 tooth, so ill just be a bit off based on my tire choice. so im going to throw in the 21 tooth

which would be stock on a explorer xlt from the mid 90's right?

can you elaborate on this part number.

Posted by: AbrahamLincoln

just ordered the purple gear part its 2 dollars :-) but it doesnt come in until tomorrow

Posted by: chickenviii

i already got the correct speedo gear for mine (entire old setup from the bird) i was making sure they didnt change from a gear to some other type of sensor. do you have a tune with your 4.10's? the reason i asked is when we threw the 3.73's in the bird years ago it stacked the shifts, you would be in 3rd by the time you crossed the intersection and the govoner would hit at i think 70 (should of been 105). i just dont wanna swap them into my 98 and end up going back to stock, cuz i aint got money for a tune right now

Posted by: 98LSC32V

No a tune won't correct for a gear change in a 98, only 99+ ECU can do that. It is nice to change the rpm shift points and firm up the line pressure with gears though. The gen 2 doesn't need speedo gears period. I think it's because the speed is read off the abs sensor not the tranny or something like that.

Posted by: AbrahamLincoln

ok is our tranny 7 or 8 tooth gears, i see that the white 23 tooth for the 4.10 is a jeep part - i got the purple gear. it has 21 teeth i guess???

i got underneeth the car yesterday, where is the bolt to get at the gear to switch? is it towards the tailshaft or where, a picture would be A mazing.

my questions have been answered... except that I have 4.10 gears - is it worth it to keep replacing with that jeep part? or is it just a lil bit off with the purple 3.73 stock from ford gear? we shall soon see today!

Posted by: 98LSC32V

It is worth using the jeep speedo gear for 4.10's-4.30's.

Posted by: AbrahamLincoln

wow your really need that speedo gear in if you have a gen 1 with 4.10's really woke my trans up, plus the added benefit of knowing the speed. ok and for who ever said it was a 10mm and real easy to do - was full of crud, its a 12mm bolt, and its at a crazy angle. it took me at least an hour because i didnt have the right tool, also the new piece didnt go on as snugly as the stock one but who knows, other than that its straight forward. get either a 3 inch extenstion and love scratching your arm on the third cat, or get a long extension wit a 12 mm socket with a pivoted socket and it will be a piece of cake 15 minute job. 12MM bolt, not 10MM

Posted by: Markviiiedrea

So I got the wrench size wrong sorry about that it was a few years ago. Stil only took me 15 min, no ext or u-joints. What did tooth size did you end up with?

Posted by: Moes8

yeah, i dont remember if its 10mm or12mm but when my gear was delivered at work , i installed it in the parking lot at work when my shift was done,it was 10 minutes tops.

like you said,its 1 bolt ,pull out swap gears stick back in and tighten.

Posted by: AbrahamLincoln

yea its 12, and it is easy if you have no third cat and the wrists of this person:

Posted by: AbrahamLincoln

rofl im sorry - all im sayin is that i got big arms and its hard to squeeze between that third cat and turn a wrench... i tried going through the suppot with an extension, but angle is such that you need a swivel. so if you dont have mary kate olson wrists, it becomes a pita but it is possible, but not in 10 minutes

i will have to look under there again for reference.

here is the place in allentown i was mentioning awhile back ,i think you were looking for a shop to do rearends.

D & D Automotive Specialties
10 Alta Dr
Whitehall, PA 18052-5623
(610) 432-0041

i never used them but i heard the do good work.

mustangs and other fords ,specialists

Posted by: AbrahamLincoln

yea they are good, guys not into mod motors, but referred me to the shop where i got my rear done up. he said he didnt have the time to do it... which i can understand if your getting big dollars for other stuff.

my guy told me i shouldn't need a driveshaft, and i havn't had bad vibes at all?? it only started to notice right after i got my tires rotated? its only noticable above 100. didnt used to be at all.

good to know,

above 100,probably means it would have vibrated at 130+mph with stock gears,not bad.

Posted by: AbrahamLincoln

yea i guess i got lucky? theres a lot of other factors that make a mark 8 prone to vibration, there is a good article about it here

http://forums.modulardepot.com/showthread.php?t=5443

many many other factors in fact.... but a driveshaft isn't a bad idea - especially if you drag race a lot or like going insanely fast all the time on the highway. but for me - if you look into the other aspects before the driveshaft you can get your way through it, however if you just wanna spend the money and know that you have a superior driveshaft that will handle insane mmounts of hp... by all means go for the drive shaft immediately.

im working on the insane ammounts of hp first :-)
