The Toyota AE86 is a beloved icon in the automotive world, particularly among drifting enthusiasts and those who appreciate the art of driving. One of the most effective upgrades for enhancing the performance of the AE86 is the installation of a TRD Limited Slip Differential (LSD). This article explores the benefits of this modification, the installation process, and the associated costs.
What is a Limited Slip Differential?
A Limited Slip Differential is a type of differential that allows for some degree of wheel speed difference between the left and right wheels while providing increased traction. This is particularly advantageous in high-performance applications, where maintaining grip during acceleration and cornering is crucial.
Benefits of Installing a TRD Limited Slip Differential
Installing a TRD Limited Slip Differential on your AE86 can yield several performance improvements, including:
- Improved Traction: The LSD helps to distribute power more evenly to the wheels, reducing wheel spin and enhancing grip on various surfaces.
- Better Handling: With increased traction, the AE86 can navigate corners more effectively, resulting in improved handling dynamics.
- Enhanced Drifting Capability: For drift enthusiasts, a TRD LSD allows for smoother transitions and better control during slides.
- Increased Stability: The LSD provides better stability during acceleration, particularly in rear-wheel-drive configurations like the AE86.
Installation Process
Installing a TRD Limited Slip Differential requires a moderate level of mechanical skill and the right tools. Here’s a step-by-step guide to help you through the process:
- Gather Necessary Tools: You’ll need basic hand tools, a jack, jack stands, and possibly a torque wrench.
- Remove the Rear Axle: Start by lifting the car and securely placing it on jack stands. Remove the rear wheels and brakes to access the differential.
- Drain the Differential Fluid: Use a drain pan to collect the old fluid as you remove the differential cover.
- Remove the Old Differential: Carefully unbolt and remove the existing differential from the axle housing.
- Install the TRD LSD: Place the TRD LSD into the axle housing, ensuring it is seated correctly. Follow the manufacturer’s torque specifications for all bolts.
- Reassemble the Rear Axle: Reinstall the differential cover, brakes, and wheels. Ensure all components are securely fastened.
- Refill Differential Fluid: Fill the differential with the appropriate type and amount of fluid as specified by TRD.
- Test Drive: After installation, take the car for a test drive to ensure everything is functioning correctly.
Cost Considerations
The cost of installing a TRD Limited Slip Differential can vary based on several factors, including whether you choose to do it yourself or hire a professional. Here’s a breakdown of potential costs:
- TRD LSD Unit: The price for a TRD Limited Slip Differential typically ranges from $800 to $1,200, depending on the retailer and availability.
- Installation Costs: If you opt for professional installation, labor costs can range from $300 to $600.
- Additional Parts: You may need to purchase additional parts such as seals, gaskets, or fluid, which can add another $50 to $150 to your total.
Conclusion
Upgrading to a TRD Limited Slip Differential on your Toyota AE86 is a worthwhile investment for those looking to enhance their vehicle’s performance. With improved traction, handling, and stability, this modification can transform your driving experience. While there are costs associated with the upgrade, the benefits it provides, especially for enthusiasts, make it a valuable addition to any AE86.
