Customer Questions & Answers
-
Question:
What is the ARRMA Diff Shim Set and what does it include?
Answer: The ARRMA Diff Shim Set is designed specifically for 29mm diff cases, allowing you to fine-tune the performance of your vehicle’s differential. This set includes shims that help adjust the spacing and preload of differentials in three separate diffs, ensuring optimal performance and durability. Proper shim placement can enhance the handling and responsiveness of your RC vehicle, making it crucial for competitive use or hobbyist modifications. -
Question:
How do I install the ARRMA Diff Shim Set?
Answer: Installing the ARRMA Diff Shim Set involves disassembling your 29mm diff case. Begin by removing the diff from your vehicle. Then, add or modify the shims based on the desired preload and spacing. Make sure to follow the manufacturer's guidelines for placement. Proper installation can significantly impact the way your vehicle accelerates, brakes, and corners, providing a more enjoyable driving experience. -
Question:
What are the benefits of using diff shims in my ARRMA model?
Answer: Using diff shims allows for precise tuning of the differentials, which can lead to enhanced stability and control during races or tough terrains. By adjusting the shim thickness, you can modify how the power is distributed to the wheels, which can improve traction and prevent unwanted slipping. This tuning is especially useful when racing or navigating rough landscapes. -
Question:
Is the ARRMA Diff Shim Set compatible with other models?
Answer: The ARRMA Diff Shim Set is specifically designed for 29mm differential cases, mainly found in select ARRMA models. While it may fit other vehicles if they use the same diff size, it's crucial to check compatibility with your specific RC model. Using the correct parts ensures optimal performance and reduces the likelihood of damage or mechanical failure. -
Question:
What materials are the shims made from?
Answer: The ARRMA Diff Shim Set is typically made from durable plastic or polymer materials, which provide flexibility and resilience under stress. These materials are chosen to withstand the forces generated during high-speed performance, ensuring longevity and reliability. Using the right materials helps maintain consistent performance over time, crucial for both competitive racing and recreational driving. -
Question:
Can I mix shims from different manufacturers?
Answer: While mixing shims from different manufacturers is technically possible, it's generally not recommended. Different brands may have variations in thickness, material properties, and fit. To ensure optimal performance and avoid compatibility issues, it's best to use shims designed specifically for your ARRMA diff case. This practice helps maintain the integrity and precision of your differential setup. -
Question:
How do diffs affect the driving dynamics of my RC vehicle?
Answer: Differentials play a critical role in managing the distribution of power to the wheels. They allow the outside wheel to rotate faster than the inside wheel during turns, improving handling and reducing tire wear. Proper tuning with diff shims can optimize these dynamics, enhancing cornering speed and stability. This capability is vital for achieving competitive edge in racing or for better maneuverability in rough terrains. -
Question:
What tools do I need to install the ARRMA Diff Shim Set?
Answer: To install the ARRMA Diff Shim Set, you’ll typically need a set of screwdrivers to remove the differential cases, a wrench for any nuts and bolts, and possibly pliers for grip. Additionally, having a clean workspace and organization tools like a parts tray can help streamline the process. Having the right tools ensures a smooth installation, minimizing the risk of damaging parts during the procedure. -
Question:
Are there any tips for tuning other than using shims?
Answer: In addition to shims, tuning other components like gear ratios and shock settings can significantly affect your RC vehicle's performance. Adjusting the stiffness of the shocks or changing the battery weight can balance the handling characteristics. Together with shims, these tuning options allow for a highly-customized setup that can cater to various driving styles or competitive scenarios. -
