Im looking for a new ring and pinion because when i bought my truck the rear end gearing doesn't match the front . Where is a good place to buy ring and pinion from? Looking for 4.10 ratio cuz i know thats whats in the front end cuz i checked that out and i have a dana 70 in the rear end and please help thank you

 

4wheelparts carries a big selection of ring and pinions. In my opinion you'll want to stick with 3.55 or 3.73 gears unless you are constantly towing 12k+. Much better fuel economy and still good for occasional towing. The rear diff should have an id tag on it that says what gears it has and if it has limited slip. Anyway mine does.

 

your suppose to have higher gear ration in the front axel so the when in four wheel it pulls an I right? if Im wrong please let me know...

 

If you have mis matched gears you'll shell your transfer case.

Higher raito in the front means the front wheels wont turn as fast as the rear wheels.

 

Would the 3.73 in the rear work with the 4.10 in the front cuz im gonna need 4x4 for winter and sense whatever is in the rear spins way faster then the front cuz tried it one day on the highway and i couldnt go over 30mph without the rearend locking up

 

No. They both have to be the same or you'll destroy your transfer case.

If you are wanting to match your rear axle and you're not sure on the gearing, open up the diff. There should be a number stamped on the ring and the pinion. You take the number on the ring and divide it by the pinion. Example: Ring gear 41, pinion 11 comes out to 3.7272 which is 3.73 gears. If there isn't any numbers stamped, you can count the teeth on the ring and divide it by the number of teeth on the pinion.

 

Yeah Bryce is right, front end gearing and rearend gearing need to match. You shouldnt drive it in 4wheel drive at all till that is adressed. I run 4.10's in my truck with 33 inch tires and it will pull ANYTHING but best tank was 22 mpg. I miss having 35 inch tires cause with the gearing it was perfect, boosted milage to 25ish and still had the power. I recomend changing your front to match the rear UNLESS you have bigger tires or are gonna tow alot. Also I recomend 4wheelparts.com, customer service is good, price is average, but good selection usually.

 

For mud racing, yes you're correct! For the road...... no ha ha

 

I called the dealership yesterday and they said stock gearing is 3.55, so i check the rearend out and thats what it has in it so today im gonna open up the front and see what it is cuz i want to be sure

 

Out of curiosity, how do you know the ratios are different? One way to check that I have used is lifting the tire off the ground, and turning the tire one revolution. While turning the wheel, count how many revolutions the drive shaft spins.
