Why You Need To Regear Jeep

Why You Need To Regear Jeep

Jeep is a brand that’s known for its cool and rugged styles. But did you know that jeep has a history of regearing? Jeep has been regearing vehicles since the 1950s. What does this mean for you? It means that jeep’s regearing can help improve its performance and aesthetics and save you money in the long run by extending the life of your vehicle. If you want to make your car look better and perform better, consider regearing it yourself.

How Does Gearing Work?

The gearing of your axles is determined by the number of teeth on the ring and pinion gears. This determines how much work your driveshaft has to do to turn the wheels. The ratio of the gear sizes (ring and pinion) is important because it determines how fast the driveshaft can rotate. The smaller the gear size, the faster the driveshaft can turn.

The drive gear ratio typically varies with vehicle type. Still, on average, it is about 3.73:1. For every turn of the driveshaft, the ring gear will rotate three times, and the pinion gear will rotate once.

When you change the gear ratio, you’re changing the speed at which the driveshaft can rotate. This affects how fast your car can go and how much torque your engine can produce.

Many factors go into a regear. It’s a complex subject that requires a lot of knowledge and experience to understand. which is why it’s vital to have a qualified technician change the gear ratios on your car.

What Does a New Set of Gears Do?

A common modification to Wranglers is installing lift kits or expanding the wheels with larger tires. Upgrading the height of your Jeep Wrangler can be done with a lift kit, just by adding suspension and frame.

A lift kit increases the height of the Wrangler by adding a frame and suspension lift. The additional height allows for increased clearance under the vehicle, which can improve ground clearance and provide an improved ride quality. Larger tires provide better traction in rugged terrain, making the Wrangler more capable off-road.

Regarding gear ratios, new gears can improve the Wrangler’s performance in various areas. A higher gear ratio allows the engine to work more efficiently, providing improved fuel economy and increased acceleration. A lower gear ratio can improve the Wrangler’s handling by reducing the number of engine RPMs at high speeds.

Why Should You Regear?

Increasing your top speed and fuel economy may be suitable if you drive a lot on the highway and your time is spent at certain speeds. You should probably install shorter gears if you plan to take your truck off-road or convert it to an ATV.

You may also want to regear if you have a heavy-duty transmission and your vehicle is not suited for a higher gear ratio. A higher gear ratio makes the engine work harder, which can result in potential overheating.

WHAT GEAR DO I NEED?

Regearing is based on a ratio, so the first thing you’ll need to assess is the circumference of your tire. Once you know the circumference of your tire, you can find the gear required to achieve that ratio.

WHAT REGEARING MEANS

The process of changing your ring and pinion gears to a different ratio is called regearing. This change balances out torque and speed. The most common regearing ratios for manual transmissions are 3.46:1 and 2.73:1.

Jeep enthusiasts have long debated the benefits of regearing the engine. Some swear by its performance enhancements, while others insist it’s unnecessary and can damage the engine. 

Nowadays, most Jeeps use a four-speed automatic transmission. Jeep engineers developed regearing technology to fine-tune the engine’s ratios without changing gearboxes to keep maximum performance potential across all gears. This means that you can always rely on your jeep’s transmission for smooth shifts regardless of which gear you are in.

If you want to step up your off-road game and have a little more power under the hood, re-gearing your Jeep JK Wrangler is a great option. A regear will not only give you more power but can also improve fuel economy and driving dynamics. Here are four reasons why you should consider regearing your Jeep:

1. More Power 

A regear will give you more power and torque across all engine speeds, giving you a boost when you need it most.

2. Improved Fuel Economy 

A regear can improve fuel economy by as much as 10 percent, which is excellent news if you’re looking to save money on gas.

3. Increased Driving Dynamics 

Improved driving dynamics can make your jeep feel sharper in the dirt, making off-roading much easier.

4. Better Connections 

A regear can also improve connections between the engine and transmission, resulting in better overall performance.

Jeep JL Wrangler ReGear Ratio

The jeep JL Wrangler is the perfect vehicle for off-road enthusiasts. It is ideal for trails and other challenging terrains because it has a great turning radius. But if you’re looking to take your Jeep JL to the next level, you’ll need to regear it.

A regearing job on a Jeep JL Wrangler will change the gear ratio of your transmission. This will allow you to run larger gears in lower ratios, making your jeep faster and easier to drive on rougher terrain.

There are three main ways to regear your Jeep JL: the transfer case, the front axle, or the rear axle. Here’s a brief look at each option:

Transfer Case Regearing

A transfer case regearing job changes the gear ratio of your transmission by changing the size of the different gears within the transmission. This is probably the simplest way to regear your Jeep JL, but it requires taking your vehicle to a dealership or workshop.

Through The Front Axle: A through-the-front-axle regearing job changes the gear ratio of your transmission by changing how many forward gears are available on each axle. This is usually done by removing one or more parts between your vehicle’s engine and rear differential assembly.

Rear Axle Regearing: A rear axle regearing job changes the gear ratio of your transmission by changing how many reverse gears are available. This is usually done by removing one or more parts between your vehicle’s engine and rear differential assembly.

Whatever regearing job you choose, be sure to understand how gear ratios work and how they impact your jeep JL’s performance. You don’t want to mistake regearing your Jeep JL incorrectly, which could damage your transmission and cause serious problems.

How Much It Costs To Regear Your Jeep?

How Much it Costs to Regear Your Jeep

Jeep owners need to regear their vehicles at least every eight years, typically when the vehicle’s original transmission can no longer handle the rig’s increased power and torque. A complete regearing job can cost anywhere from $300 to $2,000, depending on the make and model of your jeep.

Still, a good rule of thumb is that it will cost about twice as much as the repair cost for a failed transmission.

How to Regear Your Jeep?

Unless you’re familiar with changing your Wrangler’s ring and pinion gears, we recommend bringing it in for professional installation. To ensure you get the task done without surprises, we’ll provide a step-by-step guide on installing them in your vehicle.

1. Locate the ring and pinion gears in your jeep. . They’re also located on either side of the engine near the firewall.

2. Remove the bolts that secure the ring and pinion gears to the engine. Be sure to keep the gears in their respective holders.

3. Carefully remove the old gears from the engine. Make sure to keep all the bearings and debris that may have come with them.

4. Install the new gears in their holders using the bolts removed in step 2. Ensure that the gears’ teeth mesh correctly with those on the engine shafts.

5. Replace any debris left behind by removing the old gears and reinstalling them into their holders. Tighten the bolts to ensure proper fitment.

6. Reinstall the firewall and engine cover, inserting the bolts in the appropriate locations.

7. Test your jeep to ensure the new gears are working correctly.

8. Replace the air filter if necessary.

Conclusion

In conclusion, jeeps are a great option for off-roading and can be made even better with regearing. This process changes the gear ratio of your transmission, which can improve your Jeep’s power, fuel economy, and driving dynamics.

It’s important to understand how gear ratios work before attempting to regear your Jeep yourself, as an incorrect installation could damage your transmission. If you’re not confident in your ability to correctly install new gears, we recommend bringing it in for professional installation.
