Question: Do You Have To Regear For Bigger Tires?

What gear ratio is best for 33 inch tires?

So if our truck had 30-inch tires stock, and a 3.73:1 axle ratio, that calculation would tell us we need a 4.103:1 (which rounds off to the readily available 4.10:1) gear ratio to get us back to stock with 33-inch tires..

Is a 4.10 gear ratio good?

A 4.10 axle ratio will provide improved acceleration in stop and go city traffic. A lower gear (higher numerical) ratio provides more low-speed wheel torque, which makes it easier to get the vehicle moving when pulling a trailer or carrying a heavy load.

How much does it cost to Regear a differential?

Re: How much $$ to re-gear diffs Labor should be around $250/axle. That’s based on a 3-hour job per axle at a shop rate of $75/hour and rounded-up for sales tax. Parts kits (“Master” parts kits, including all bearings, races, ring bolts and shims) are about $125/axle. The actual ring & pinion sets are about $150/axle.

Should I Regear my Tacoma?

It’s a combo of a number of things, but specifically crap gearing in the Tacoma. In short, yes you should regear. … As to which gears, That really depends on what else you’ll be doing to the truck. If you plan to go to 35’s some day or add a ton of armour and weight like me, go 5.29’s.

Are 3.73 gears good?

A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.

How much does it cost to Regear JK?

Just a regear will run around $1200 to $1600 depending on the shop.

Is 3.42 or 3.73 better?

The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.

Will Regearing help mpg?

Regearing will help correct the odometer and the perceived power loss, but not significantly for the MPG. They are called the laws of physics for a reason…

Do I need to Regear for 35s?

No, you don’t need to re-gear with 35s. However, definitely plan on a re-gear in the future and fall in love with your Jeep all over again. She loses pep with bigger meats without the regear – especially with the heavier 35″ tires.

How far off is my odometer with bigger tires?

Over the length of 1 mile, this adds up to 33.6 feet. After “actually” traveling 157 miles, the odometer will be “off” by 1 mile. It will read 158 miles. Smaller diameter tires will effect odometer reading more than larger tires.

How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

Will bigger tires affect gear ratio?

Calculating Effective Drive Ratio As you can see, the larger tires reduce your final drive ratio to 3.30—a measurable difference. You can also do this to determine the effect of smaller tires on your final drive ratio.

What’s the difference between 4.10 and 3.73 gears?

simply a higher gear ratio means less speed but more torque, for example in the cars, the 1st gear in the transmission the gear ratio is 4.10 and the 2nd gear the gear ratio will be 3.73 ….. to the 5th 0.75 (for example). The 4.10 will give slightly better acceleration and increase engine rpm at any given speed.

Can I run 35s with 3.73 gears?

I ran 35s with 6 speed and 3.73 on my last JK 2013, no real complaints. I never felt at a loss both city and wheeling. You will lose 6th gear sometimes as mentioned but you can still utilize it. I’ve also run 35s with a 2010 JK and a 6 speed with even 3.21s.

Do bigger tires reduce gas mileage?

For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.

How much does it cost to Regear your truck?

If you can drop off the rear 3rd member and front diff expect prices to range from $400-700. If you drop off the truck add another $300-500.
