Customer Questions & Answers

  • Question: What vehicles are compatible with the EXCEL 12BC373 Ring & Pinion Set?

    Answer: The EXCEL 12BC373 Ring & Pinion Set is designed to fit GM 8.875" 12-bolt differentials. This includes a variety of GM models, particularly those using the 8.875" rear-end assembly. It's essential to confirm compatibility with your specific vehicle model to ensure proper fitment. Properly matching this set with the correct vehicle details not only enhances performance but also optimizes durability.
  • Question: What ratio does the EXCEL 12BC373 provide and why is it important?

    Answer: The EXCEL 12BC373 Ring & Pinion Set features a 3.73 gear ratio. This ratio is significant because it strikes a balance between acceleration and fuel economy, making it ideal for both street and light off-road use. By choosing this gear ratio, drivers can experience better torque and performance without sacrificing drivability, particularly when paired with appropriate tires and vehicle weight.
  • Question: What spline count does the EXCEL 12BC373 have?

    Answer: The EXCEL 12BC373 Ring & Pinion Set has a 30 spline count. This count is crucial for ensuring that the pinion gears mesh correctly with the axle shafts, providing strength and reliability under load. Higher spline counts typically indicate a stronger connection, which is particularly advantageous in performance applications where stress is greater.
  • Question: What carrier is required for the EXCEL 12BC373 Ring & Pinion Set?

    Answer: The EXCEL 12BC373 requires a 3.90 or higher carrier for optimal performance. This is essential because the carrier supports the ring gear, and using the correct carrier ensures that the gear mesh is aligned properly for efficient power transfer. If not matched correctly, it can lead to premature wear or failure under load.
  • Question: Can the EXCEL 12BC373 replace other ring and pinion sets?

    Answer: Yes, the EXCEL 12BC373 Ring & Pinion Set replaces GM 742H730C while also being compatible with other brands like Richmond, Yukon, and Motive Gear. This versatility allows for easy upgrades or replacements for performance enthusiasts looking to enhance their differential's response without completely changing their setup.
  • Question: How does the installation process of the EXCEL 12BC373 compare to others?

    Answer: The installation of the EXCEL 12BC373 Ring & Pinion Set is similar to that of other aftermarket gears, requiring precision and attention to detail. Proper set-up involves adjusting backlash and gear contact patterns, which are critical for ensuring that the gears operate smoothly. It's recommended to have experienced mechanics or enthusiasts handle the installation to achieve optimal performance.
  • Question: What benefits do I get by upgrading to the EXCEL 12BC373?

    Answer: Upgrading to the EXCEL 12BC373 Ring & Pinion Set can significantly enhance your vehicle's acceleration and overall performance. This gear set allows for a better power band, particularly beneficial when towing or carrying heavy loads. Users often report improved throttle response, making it an excellent choice for both daily drivers and off-road vehicles.
  • Question: What kind of maintenance is required for the EXCEL 12BC373?

    Answer: Maintaining the EXCEL 12BC373 Ring & Pinion Set primarily involves regular inspections of the differential fluid and ensuring proper lubrication. It's also advisable to check for any unusual noises or vibrations that could indicate wear. Consistent maintenance helps extend the life of the ring and pinion set, ensuring reliable performance in various driving conditions.
  • Question: Is the EXCEL 12BC373 suitable for off-road applications?

    Answer: Yes, the EXCEL 12BC373 Ring & Pinion Set is suitable for moderate off-road applications. Its durable construction and optimized gear ratio make it capable of handling the stresses associated with off-roading, such as increased torque and load. Whether navigating trails or rugged terrain, this gear set supports enhanced performance for adventurous driving experiences.
  • Question: Where can I buy the EXCEL 12BC373 Ring & Pinion Set?
