What kind of differential does a Mustang have?
Modern Mustangs predominantly use an independent rear suspension (IRS) with a limited-slip differential in most trims, while older models relied on a solid rear axle with an open or limited-slip differential depending on year and option packages.
To understand what kind of differential a Mustang has, it helps to separate history from current configurations. The early cars (1964–2014) used a live rear axle with a rear differential, with Traction-Lok or other LSD options available on higher-performance variants. Since the 2015 redesign, Ford switched to IRS for improved ride and handling, and the rear differential in most trims is a form of limited-slip differential—often electronically controlled—though the exact type (open, mechanical LSD, or electronic LSD) varies by model year, trim, and package. Always check the specific build sheet or VIN for precise specifications on a given car.
Historical differential configurations
The following overview highlights the primary differential setups Mustang buyers would have encountered across generations:
- 1964–2014: Solid rear axle (live rear axle) with a rear differential. Many base cars shipped with an open differential, while performance-oriented variants offered a Traction-Lok limited-slip differential as an option or standard.
- 2015–present: Independent rear suspension (IRS) with a rear differential. Most trims include some form of limited-slip differential, with the exact type (electronic or mechanical) depending on year and package.
In short, if you’re looking at a classic or mid-generation Mustang, expect a solid rear axle with an open or limited-slip differential; if you’re eyeing a newer model, the IRS paired with a limited-slip unit is standard on most trims, with variations by package.
Current differential configurations by model year/trim
For the current generation, the differential option is closely tied to the trim level and any performance packages you choose. Here is a general guide to what you may find across popular configurations:
- EcoBoost (2.3L): Base models often come with an open differential, with the option to add a limited-slip differential via performance or handling packages.
- EcoBoost with Performance Package: Typically features an electronic limited-slip differential (eLSD) to improve traction during spirited driving and cornering.
- GT (5.0L): Generally equipped with a limited-slip differential; higher trims or packages may include an electronically controlled LSD for enhanced grip and stability on the street or track.
- Special editions and higher-performance variants: These models tend to use more robust diffs, often electronically controlled, designed to handle higher horsepower and more aggressive driving, with additional cooling or stronger clamping force as needed.
Note that specifications can vary by model year and option packages. Always verify the exact differential type with the dealer or via the vehicle’s build sheet.
Maintenance and practical considerations
Limited-slip differentials require periodic service—diff oil changes at recommended intervals and careful attention to wear on clutch packs (for clutch-type LSDs). If you track a Mustang or drive aggressively, an enhanced LSD setup can improve traction, but it may also require more frequent maintenance and attention to tire wear.
Summary
Across the Mustang lineup, the differential has evolved from a traditional live rear axle with open or Traction-Lok LSD to a modern independent rear suspension paired with a limited-slip differential, frequently electronically controlled. The exact setup varies by year and trim, so buyers should check the specific build sheet or VIN to confirm whether a car has open, mechanical LSD, or electronic LSD, and which version is installed for that model. Understanding the differential is key to assessing a Mustang’s handling characteristics and potential track readiness.
Are Mustangs solid axles?
And cons of each setup to help you determine. What's going to be the best for your driving. Style. The Ford Mustang. Since 1964. And a half has always had a solid axle.
Does the Mustang GT have a limited-slip differential?
Yes, all modern Mustang GTs have a limited-slip differential (LSD) as a standard feature. The specific type of LSD can vary by model year and trim, with standard models often getting a Traction-Lok (clutch-pack) LSD and performance-oriented packages typically upgrading to a Torsen (worm-gear) LSD.
Key details
- Standard on GT: Ford has equipped the Mustang GT with an LSD as a standard feature for many years, including all models since 1986.
- Standard on S550: Since the S550 generation (2015 onwards), all Mustang models, including the GT, come standard with an LSD.
- Traction-Lok vs. Torsen:
- Traction-Lok: This is a mechanical clutch-based limited-slip differential that is standard on most GT models.
- Torsen: This is a higher-performance worm-gear limited-slip differential that is included in the Performance Package and other performance-oriented trims on various model years.
Are Mustangs open diff?
So if one tire starts spinning or one tire is in the mud or ice or whatever that tire will get more torque. And start spinning.
What are the 4 types of differentials?
Different types control how much or little power makes it to the wheels. There are four common types of differentials on the market – open, locking, limited-slip and torque-vectoring.
