Description

You can dramatically improve the traction and handling of your performance vehicle with the Mastodon Ford 9″ Track Lock Differential Carrier. We engineer this carrier to maximize power delivery to both rear wheels. It features the proven clutch-style Track Lock limited-slip design. Furthermore, it includes heavy-duty 31-spline side gears that mate perfectly with robust aftermarket axle shafts. This combination ensures predictable handling, superior straight-line launches, and enduring strength under extreme conditions. Consequently, this carrier is an essential upgrade for you if you plan on street driving or competitive racing. As a trusted supplier in Alberton, Gauteng, we deliver reliable drivetrain components across South Africa.

Key Features

• Ford 9″ Axle Specific: Engineers designed this carrier for a direct fit into the iconic Ford 9-inch housing. This ensures perfect alignment and hassle-free installation into your existing pumpkin.
• Track Lock (LSD) Operation: The clutch-style limited-slip design biases torque to the wheel with the most traction. This effectively eliminates the frustrating and power-wasting “one-wheel peel.”
• 31-Spline Side Gear Capacity: The carrier utilizes heavy-duty 31-spline side gears. This makes it compatible with the strongest axle shafts commonly used in performance and high-horsepower applications.
• Durable Construction: The housing is crafted from high-strength nodular iron. This material provides maximum resistance to deflection and housing fatigue under the stress of hard launches.
• Enhanced Handling: The LSD action provides predictable traction through corners. This gives you increased confidence and control on both the street and the track.
• Rebuildable Design: The clutch pack is accessible and replaceable. Therefore, you can service and tune the carrier for customized preload and longevity.
• Nationwide Shipping: We deliver performance components across South Africa.

Why Choose the Mastodon Ford 9″ Track Lock Differential Carrier?

A reliable limited-slip differential is mandatory because it fundamentally changes how your power reaches the ground. Standard open differentials often spin the inside tire during acceleration. This wastes valuable horsepower. By contrast, the Mastodon Track Lock proactively engages its clutch pack. This ensures that engine power is distributed evenly to both wheels. Moreover, choosing the 31-spline version gives you the flexibility to install larger, stronger axles. Ultimately, you invest in a durable, performance-focused unit that significantly improves both your vehicle’s safety and its overall performance capabilities.

Frequently Asked Questions

1. What is the main benefit of the Track Lock over a standard open carrier?
   The main benefit is improved traction. The Track Lock provides power to both wheels, whereas an open carrier sends power to the wheel that has the least resistance. Consequently, you get more effective acceleration and better control.
2. Why should I choose 31 spline over 28 spline?
   The 31 spline side gear accommodates a thicker, stronger axle shaft. This provides significantly higher torque capacity. We highly recommend the 31-spline option for high-horsepower or heavy-duty applications.
3. Does this carrier require a special additive?
   Yes, because it is a clutch-type limited-slip differential. You must use a high-quality gear oil along with an LSD friction modifier additive. This ensures smooth, quiet operation of the clutch pack.
4. Can I use my existing axle shafts with this carrier?
   You can only use your existing axle shafts if they are 31-spline units. If you currently have 28-spline axles, you must upgrade them to 31-spline units to match this carrier.
5. Is installation difficult?
   Differential installation requires precise measurement and setup of backlash and bearing preload. We strongly recommend that you have a professional drivetrain specialist perform the installation.
6. Will this carrier work with any gear ratio?
   Carrier cases are typically split by ratio range (e.g., 2.75-3.50 and 3.70-up). You must specify your intended gear ratio when ordering to receive the correct carrier housing.
7. Do you offer nationwide shipping?
   Yes, we offer fast and reliable nationwide shipping across South Africa. You can order from anywhere in the country. All orders are processed and shipped from our location in Alberton.
