Description
Product Overview
Briny River stainless steel shims are engineered for precision performance in RC car differentials. These shims feature exact 16mm outer and 13mm inner diameters to ensure perfect fitment in most RC vehicle differential systems. Constructed from high-quality stainless steel, they offer exceptional durability and rust resistance for long-term reliability. The ultra-thin 0.15mm thickness allows for meticulous gear mesh adjustment, reducing unwanted play and optimizing drivetrain efficiency. Each set includes 20 shims, providing ample supply for multiple tuning sessions or replacements. Model KYO96772 maintains consistent dimensions of 5 x 3.07 x 0.01 inches in package size with individual shims weighing just 0.704 ounces, ensuring minimal impact on overall vehicle weight while delivering maximum performance benefits.

Usage
These precision shims are designed for RC car enthusiasts and professional racers who require optimal differential performance. They are ideal for tuning sessions where precise gear mesh adjustment is crucial for competitive racing or hobbyist enjoyment. The shims work effectively in various RC vehicle types including buggies, truggies, and on-road cars where differential play affects handling and acceleration. Installation occurs during routine maintenance or performance upgrades, particularly when seeking to eliminate gear lash and improve power transfer efficiency. The target audience includes RC hobbyists at all skill levels, from beginners learning vehicle maintenance to experienced racers fine-tuning their competitive edge.

FAQ
What RC car models are these shims compatible with?
These shims are designed to fit most standard RC car differentials that accept 16mm outer diameter and 13mm inner diameter shims. They work with popular brands including Traxxas, Arrma, Associated, and other major RC manufacturers. Always verify your specific model’s requirements before installation.
How do I install these differential shims?
Installation involves disassembling your RC car’s differential case, placing the shim between gear components where spacing adjustment is needed, then reassembling. The ultra-thin design allows for precise stacking if multiple shims are required for optimal gear mesh. Always follow your vehicle manufacturer’s specific disassembly and reassembly procedures.
Can these shims be used in other applications beyond RC cars?
While specifically designed for RC car differentials, these stainless steel shims may work in other small mechanical applications requiring 16mm outer diameter, 13mm inner diameter spacing components. However, we recommend them primarily for their intended RC differential application to ensure optimal performance.
What makes stainless steel better than other shim materials?
Stainless steel provides superior corrosion resistance, maintaining dimensional stability and performance in various environmental conditions. Unlike materials that may degrade over time, stainless steel ensures consistent thickness and strength, crucial for maintaining precise gear mesh in high-performance RC applications.
How many shims should I use for optimal performance?
The number of shims required depends on your specific differential setup and desired gear mesh. Start with one shim and test the gear play, adding additional shims as needed until you achieve minimal play without binding. The 20-piece set provides flexibility for fine-tuning multiple vehicles or making adjustments over time.
