What are the benefits of a 335i diff retrofit for my Ford?

Benefits of a 335i diff retrofit ford

Improved Traction And Stability

Swapping to a 335i differential enhances traction, especially in rear-wheel drive Fords. The upgrade allows for better grip on the road, reducing wheel spin and providing a more stable driving experience, especially in corners or during aggressive acceleration.

Enhanced Handling

The 335i diff retrofit offers more precise handling. It improves the car’s cornering ability, giving you more control over the vehicle. This is especially beneficial for performance-driven drivers who want to improve their Ford’s responsiveness during high-speed maneuvers.

Sportier Driving Experience

With the 335i diff, you’ll notice a more dynamic and engaging driving feel. The upgrade provides a sportier response, especially during hard cornering or acceleration, giving you that performance-oriented driving experience you crave.

Durability And Longevity

BMW’s 335i differential is known for its durability, and retrofitting it to your Ford can add strength and longevity to your vehicle’s drivetrain. This means fewer issues and maintenance needs in the long run, allowing for consistent performance.

Better Overall Performance

A 335i diff retrofit unlocks better overall performance, including quicker acceleration and more precise torque distribution. This modification is ideal for Ford owners looking to improve their vehicle’s responsiveness, whether on the street or the track.

How Does A 335i Diff Retrofit Improve Ford’s Performance?

A 335i diff retrofit improves a Ford’s performance by providing better power distribution and enhanced traction. The BMW 335i differential is designed to offer quicker and more precise torque delivery to the wheels, resulting in improved acceleration and handling. 

This allows for better control, especially during aggressive cornering or high-speed driving. Additionally, the retrofit helps to reduce wheel spin and improves stability, making the car more responsive and balanced in various driving conditions.

What Maintenance Is Required After Installing A 335i Diff Retrofit In A Ford?

Regular Fluid Checks And Changes

After the retrofit, check the differential fluid levels regularly to ensure smooth operation. High-quality gear oil should be used, and it may need to be changed periodically, especially if the vehicle undergoes intense driving.

Inspect For Leaks

Watch for any signs of oil leaks around the differential seals. New seals may be installed during the retrofit, but checking for leaks ensures the system remains sealed and functioning optimally.

Monitor For Unusual Noises

Listen for any unusual sounds from the differential, such as grinding or whining, which could indicate alignment or wear issues. Addressing these early can prevent larger, more costly repairs.

Check For Proper Torque Settings

Retorque the bolts and fasteners after some driving time, as vibrations may loosen them. Ensuring everything remains tightly secured supports the longevity and safety of the differential.

Inspect Axles And Mounts

The retrofit may add strain on the axles and mounts, so it’s good to check them periodically. Look for any signs of wear or damage and replace components if needed to maintain optimal performance.

Differential Bushing Maintenance

Over time, bushings may wear down, especially if you drive the car aggressively. Inspect the bushings for wear and replace them if necessary to reduce vibrations and maintain stability.

Does The 335i Have A Limited Slip Differential?

Yes, some BMW 335i models come with a limited slip differential (LSD), but it depends on the specific model and year. Most standard 335i models are equipped with an open differential, which distributes torque evenly to both wheels. 

However, certain performance-oriented 335i versions, such as those in the M Sport package or those upgraded with BMW’s M Performance parts, may feature an LSD. Additionally, many 335i owners choose to install aftermarket LSDs to improve traction, handling, and overall.

Faqs About 335i Diff Retrofit For Ford:

Will A 335i Diff Retrofit Impact My Ford’s Fuel Efficiency?

While a 335i diff retrofit can slightly reduce fuel efficiency due to improved performance and traction, the change is generally minimal. For most drivers, the benefits in handling and stability outweigh the minor impact on fuel consumption.

Do I Need To Upgrade Other Components When Installing A 335i Differential In My Ford?

Upgrading other components, like axles, mounts, or bushings, can help optimize performance with a 335i diff retrofit. While not always necessary, these upgrades enhance durability and ensure compatibility.

How Long Does It Take To Install A 335i Diff Retrofit On A Ford?

Installation time varies depending on experience and equipment but generally takes between 4-8 hours. Professional installers may complete it faster, while DIY installations may take longer.

Can I Use A Used 335i Differential For A Ford Retrofit?

Yes, a used 335i differential can be used for a retrofit, provided it’s in good condition. Checking for wear, leaks, and other signs of damage is essential to ensure reliability and performance.

Does The 335i Diff Retrofit Affect My Ford’s Warranty?

Retrofitting a 335i differential may void the vehicle’s warranty, depending on the terms. It’s advisable to check with the manufacturer or dealership if the vehicle is under warranty before making modifications.

Conclusion

335i diff retrofit can be a rewarding upgrade for Ford owners looking to enhance their vehicle’s performance, handling, and overall driving experience. While the installation may require some adjustments and, in some cases, additional component upgrades.

With proper maintenance, this retrofit can offer long-lasting improvements, giving your Ford a more dynamic, sportier feel on both daily drives and performance-focused adventures.
