Do I Need To Regear My Jeep With 35s

Regearing is what allows you to swap the ring gears and pinion gears into different ratios. It’s essential to make an ideal balance between twisting force and speed for your jeep.  But if you have the same query hovering around your mind like, Do I need to regear my Jeep with 35s?  Here’s what you need to know. 

The most frequent remarks as well after regearing their Jeep is “WOW! Why didn’t I do this sooner?” So, you might get what you are wondering about. Adding 35s tires means a heavy weight that is tough to handle in the first phase for a Jeep. In this case, regearing is the best way to get the efficiency and power back to Jeep. 

However, there are more essential reasons why you need to regear your Jeep after installing 35s tires.

Do I Need To Regear My Jeep With 35s


It’s not mandatory like you’ll have to regear with 35s. However, regearing will assist you in saving your Jeep from unexpected damages. Here are the 5 crucial reasons why you should regear jeep with 35s

1. Performance

The regular performance of a Jeep gets down immediately right after installing the 35s tires. At this point, you need to regear your Jeep to allow it to be used to run with such weighted tires in terms of longer rotation. 

2. Size Adjustment 

When you add 35s, your Jeep needs to adjust to this vast size of the tires. In this case, regearing comes into great consideration. Adding 35s can lead you to an improper gearing trait most of the time. And, wrong gearing will cause excessive stress that will be transferred to the axle.  Therefore, regearing is required for the tires’ size adjustment

3. Recover the Power Loss

Adding 35s to the Jeep means incorporating more weights. And this condition can lead to a power loss to your Jeep. Here, regearing is the only option to go through and it also helps you maintain performance in any sort of terrain. 

4. Recover Slow Speed

A Jeep goes through a slower speed right when it gets the big-size 35s. It’s because the vehicle’s engine struggles a lot to adjust to the newly required speed. Considering the slower speed, regearing your Jeep will come in handy. 

5. Helps Find the Right Gear

A newly installed 35s Jeep gains more resistance. Therefore, it could change its gear to ensure less fuel consumption and better performance. In this situation, it’s surely a difficult job for you to find which gear to hold. 

And this is exactly where the regearing comes into consideration. Regearing will help you to hold the right gear immediately. So, you no longer have to be worried about finding the right gear. 

Cost to Regear Your Jeep

Depending on some variables like the type of your Jeep, things to be done, or place where to be done, the cost to regear will vary anywhere between $1200 to $3000. Cost to regear your Jeep can be more or less based on

  • Tire size re-programming
  • Front and rear axles
  • Front seals
  • Installation kits for ring and pinion 
  • Labor 

There can be more variables depending on where you buy from.

How to Find the Accurate Gear Ratio 

Selecting the exact gear ratio isn’t always so easy while regearing a Jeep. Considering this, we’ve prepared a gear ratio chart based on the model of your Jeep with 35s. Check out the chart to ease your regearing

What Procedures to Follow for Regear Break-In?

There should be some safety measures for the longevity of gear. So, here are some of the important steps to follow right after regearing a Jeep

  • Regular Driving Condition

Keep your driving condition as normal as you can. We strongly recommend avoiding race, hard start, off-road, towing, or highway speed. After regearing, your Jeep cannot go with things like immediate hard start or high-speed manners.

  • Regular Stoppage and Driving

Run your Jeep considering normal driving and stop in the first 20 minutes. Driving the vehicle inside town will be the best choice. After that, let the Jeep cool down. This process will save the gear from reaching high temperatures that can break down the gear oil. 

  • Maintain Cooling Time Segments

Regearing requires a cooling period. So here, you must repeat a 15-minute drive. And in each of these 15 minutes of driving,  repeat the cooling time as well. It can be 2 to 4 times. 

  • Highway Driving

Once you finish maintaining the cooling time segments, you’re ready to go for highway driving. However, keep your speed within 65 MPH and allow the axle assembly to cool down completely in between your highway driving times. Repeat this cooling process two times minimum. 

  • Change the Gear Oil 

Finally, you should change the gear oil. But before you change the gear oil, make sure the Jeep runs at least 500 miles.  

Can A Jeep With 35s Runs Without Regearing?

Yes, you can run the Jeep without regearing if you are confident enough. It’s not fixed to regear a Jeep while installing large-size tires, for example, 35s. However,  some unconditional damage might happen at the end of the day. 

The Jeep will lose its crucial top-end power in terms of overlooking the regearing trick. What’s more, the jeep will surely lose its pep while not getting regear. So, regearing is important no matter if you can run your Jeep. 


What does the regearing ratio mean?

Well, the regearing ratio determines the number of times the Jeep drive shaft needs to rotate. The driveshaft rotating is required to spin the wheels. 

How do I know which gearing my Jeep has?

There will be a tag attached to the cover of the Jeep cover bolts. Some numbers will be written on the tag, for instance, 3.54. This number is your Jeep gearing ratio/stock axle ratio. 

What does a higher gear ratio mean?

Well, the higher gear means the shorter ratio which delivers faster acceleration. However, if you want a high speed, hold for a lower gear ratio (here, the lower gear means a taller gear ratio). 


It’s normal if you’re confused like “do I need to regear my Jeep with 35s?” All of it depends on the condition of your Jeep. The 35s tires are a huge size which requires adjustments with the Jeep. Thus, you need to regear for an ideal adjustment.
Again, if the gas gauge declines faster at high speed, you must go for regearing with 35s. And when the Jeep is incapable of keeping up with traffic, you need to go for regearing. What’s more, regearing is important for an adjustment with the tires’ size and your jeep.
