The Detroit Truetrac Limited Slip Differential (LSD) is a popular upgrade for Chevy Silverado owners looking to enhance traction and performance. This article outlines the step-by-step installation process, estimated costs, and performance benefits of the Detroit Truetrac LSD.
Understanding the Detroit Truetrac LSD
The Detroit Truetrac is a gear-driven limited-slip differential that provides better traction compared to an open differential. It uses helical gears to transfer torque to the wheel with the most grip, making it ideal for off-road and performance driving.
Tools and Materials Needed
- Detroit Truetrac LSD kit
- Socket set
- Torque wrench
- Jack and jack stands
- Gear oil
- Drain pan
- Shop towels
- Safety glasses
- Gloves
Step-by-Step Installation Process
Step 1: Prepare the Vehicle
Begin by parking the Chevy Silverado on a flat surface. Engage the parking brake and place wheel chocks behind the rear wheels for safety. Use a jack to lift the vehicle and secure it with jack stands.
Step 2: Remove the Differential Cover
Place a drain pan under the differential to catch any fluid. Remove the bolts securing the differential cover and carefully pry it off. Allow the old gear oil to drain completely.
Step 3: Remove the Old Differential
Once the fluid is drained, remove the ring gear bolts and take off the ring gear. Next, remove the differential case by taking out the bolts holding it in place. Carefully slide the old differential out of the axle housing.
Step 4: Install the Detroit Truetrac LSD
Clean the differential housing thoroughly before installation. Place the Detroit Truetrac LSD into the housing, ensuring it fits securely. Reattach the ring gear to the new differential using the bolts and torque them to the manufacturer’s specifications.
Step 5: Reassemble the Differential
Once the Truetrac is installed, replace the differential cover using a new gasket for a proper seal. Tighten the cover bolts in a crisscross pattern to ensure even pressure.
Step 6: Refill with Gear Oil
After reassembling the differential, refill it with the appropriate gear oil. Consult the owner’s manual for the correct type and amount of oil required for your Chevy Silverado.
Step 7: Test Drive
Lower the vehicle from the jack stands and remove the wheel chocks. Start the engine and take the truck for a test drive to ensure the differential operates smoothly. Listen for any unusual noises and check for leaks.
Estimated Costs
When considering the installation of a Detroit Truetrac LSD, it’s important to factor in both parts and labor costs. Here’s a breakdown:
- Detroit Truetrac LSD kit: $500 – $700
- Labor (if not DIY): $200 – $400
- Gear oil and supplies: $50 – $100
Performance Benefits
Upgrading to a Detroit Truetrac LSD offers several performance benefits that enhance the driving experience:
- Improved traction in slippery conditions
- Better cornering stability
- Increased power transfer to the wheels
- Reduced wheel spin during acceleration
Conclusion
Installing a Detroit Truetrac LSD on your Chevy Silverado can significantly enhance its performance and driving capabilities. With the right tools and a bit of patience, this upgrade can be accomplished as a DIY project. Enjoy the improved traction and stability that comes with this valuable modification!
