Quadra Drive 2 vs Quadra Trac 2

Jeeps come with either four-wheel drive or Quadra-Trac (sometimes called Quadra-Drive). An explanation of quadra drive vs quadra track is that Jeeps with four-wheel drive are more rugged and will provide better traction in the snow or on rough terrain.

Quadra-Trac is less expensive and easier to maintain but does not have as good a grip on all surfaces, such as sand. Let’s talk about Quadra Drive 2 vs Quadra Trac 2.

Quadra Drive 2 vs Quadra Trac 2

What’s the difference between Quadra-Drive and Quadra-Drive 2?

Quadra-Drive is a 4WD system that includes front and rear differentials. Quadra-Drive 2 is a more recent 4WD system that also includes a low-range center differential. However, the differences between Quadra-Trac and Quadra-Drive systems are minimal.

Most people who are considering buying a Jeep with Quadra-Drive or Quadra-Drive 2 are actually comparing the different types of four-wheel drive.

Quadra-Trac and Quadra-Drive systems are also very similar in that both systems shift power between the front and rear axles and can be manually switched to 2WD. However, Quadra-Trac cannot go into low range on its own, but it can if the driver switches to 4WD Low.

What does Quadra-Drive 2 mean?

Quadra-Trac 2 is the latest 4WD system released by Jeep. This brand-new system was designed to be more efficient and less expensive than Quadra-Trac. Quadra-Drive 2 has been installed in several Jeep vehicles including the Grand Cherokee, Liberty, and Wrangler.

Quadra-Drive 2 is a 4WD system with a center differential that can be manually switched into low range on its own or when the driver manually switches into 4WD Low.

What is Command Trac?

Command-Trac was the first permanent four-wheel drive system released by Jeep. This system was released in 1984 and used a special powertrain control module (PCM) for all transfer cases.

The PCM controlled the torque in each axle and enabled four-wheel drive, two-wheel drive, and high-range 4WD (sometimes called “sport” mode). The low-range 4WD mode was activated by moving a lever from the high to the low range.

What is Jeep Rock Trac?

Rock-Trac was the second permanent four-wheel drive system released by Jeep. This system was released in 1992 and included a transfer case and rear axle with a locking differential.

The Rock-Trac transfer case had two modes: 4WD Low and 4WD High. The high-range mode was selected by moving a lever, while the low-range mode required an additional shift lever.

Quadra-Drive 2 problems

Quadra-Drive 2 has exhibited more severe symptoms in some Jeeps than in Quadra-Trac. The issues are related to the transfer case axle-locking differential. Jeep has issued several recalls for Quadra-Drive 2, many relating to transfer case axle locking differentials and the possibility of complete loss of power, which could occur when the vehicle goes into mud or snow.

Jeeps with Quadra-Drive 2 have also been recalled for issues such as power steering, damaged towing hooks, short circuits in the transfer case, and front axle vibrations. However, not all vehicles with Quadra-Drive 2 have shown these problems.

Company officials note that the issues are extremely rare and claim that the system is thoroughly tested with extreme drive cycles before vehicle installation.

This system can be compared to the Command-Trac version of four-wheel drive which has experienced its own share of problems.

Jeep quadra trac ii system

The Quadra-Trac II system is a major departure from the older systems and some people have complained that it is harder to use. The most common criticism is that the system cannot read tire pressure sensors and thus cannot indicate which tire needs air.

The system is also more expensive since it includes an active part called “E-case”, which switches gears within the transfer case based on torque need or speed.

There are a few minor distinctions between the systems, but they are mostly the same. The biggest difference is that Quadra-Trac does not have a low range, which means it cannot handle steep slopes as well. Newer systems also include a differential lock in the center axle.

When comparing Jeep vehicles with different types of four-wheel drive, it is useful to remember that some models can go into low range on their own, and some require manual shifting.

What is the difference between Quadra-Trac I and Quadra-Trac II?

Quadra-Trac I is the oldest permanent four-wheel drive system released by Jeep. The first Quadra-Trac was installed in 1993 and came with a transfer case, rear axle, and locking differential. The system could be manually switched between the high range and low range. 

Quadra-Trac II was released in 2003 and included center differential locking differentials but did not include a low range. It could be manually switched between the high range and 4WD Low (four-wheel drive).

How do I know if my Jeep has Quadra-Trac 2?

The easiest way to identify whether your vehicle has Quadra-Trac 2 is if it says “Quadra-Drive II” on the transfer case. If it doesn’t say that, look for a part number stamped on the transfer case under the Jeep logo. You will find TRKD2 stamped into the transfer case casting on vehicles with Quadra-Drive II.

Check the transfer case for the Quadra-Drive 2 stamp

Quadra-Trac II, like Quadra-Trac, is a permanent 4WD system with a transfer case and axle that can be manually switched between the high and low range. The difference is that it also includes a center differential lock in the rear axle.

Check the DHF

All vehicles with Quadra-Trac II have an electronically controlled center differential that automatically locks the axle in the high range when driving on the highway at high speeds. When driving off-road, the center differential unlocks, providing better traction through the low range.

Quadra-Drive II uses a transfer case-mounted electronic module called “Differential Housing Fan”, or DHF, to control the center differential lock. The DHF detects vehicle speed and controls the interaction between the front and rear axles.

Which Jeep is the 4WD system best?

Quadra-Drive II is better than Quadra-Trac in all Jeep vehicles. The new system practically eliminates issues by keeping the axle locked at high speeds and includes a front differential lock for off-road use. 

It is even compatible with Jeep’s new electronic stability control (ESC) system, which provides maximum traction by regulating the input torque to each wheel while driving on wet roads or off-road.

Which Jeeps models have Quadra-drive II?

What model of Jeep gets the best gas mileage?

Jeep Cherokee Latitude – The Cherokee Latitude offers a good mix of features, performance and fuel economy. It received a five-star overall rating in the 2011 IIHS “Residual Value Awards” and achieved an overall crash test score of “good” from the NHTSA.

How do I know if my Jeep has a limited-slip differential?

A limited-slip differential controls the pressure the transmission applies to the differentials on each axle, allowing power to be transferred to the wheels with more traction when required. The type of differential installed in a vehicle can be identified by a number stamped into it.

The new system is based on a standard four-speed automatic transmission. It features a pre-programmed computer on the transfer case that monitors driving conditions and adjusts friction to the axles when needed. The computer monitors driving conditions and transmits the information to both axles, transmitting signals to each other.

What does an ELSD motor do?

The electronic limited-slip differential, or ELSD, is an electronic traction aid that continually monitors wheel spin and adjusts the power split between the rear wheels in both on- and off-road conditions to enhance traction.

Can you off-road with Quadra-Trac 1?

Yes, you can go off-road with Quadra-Trac 1, although some tires will last longer than others. When driving off-road on a Quadra-Trac I system, you need to remember that if one of the tires starts to spin, 100% of the power is sent to that tire and leaves the other three disengaged.

Therefore, it is important to find a good balance between traction and fuel economy for this setup.
