KYO96642 4x6mm Sim Set

Designed as a precision tuning shim pack for Kyosho RC drivetrains and suspension assemblies, this 4x6mm set is used to remove unwanted play and fine-tune spacing between bearings, gears, and rotating shafts. The small-format shims help improve alignment accuracy in tight mechanical areas where even minor clearance changes affect performance. Multiple thickness options allow step-by-step adjustment for smoother drivetrain operation and reduced wear. Lightweight metal construction ensures durability without affecting balance in small-scale and competition setups. Commonly used in gearbox, axle, and differential spacing applications across compatible Kyosho platforms.

Features:

• Compatible with Kyosho RC vehicles using 4x6mm shim locations, including select buggy and Optima-series platforms
• Used for precise spacing adjustment in gears, bearings, and drivetrain assemblies
• Helps reduce drivetrain slop and improves mechanical efficiency under load
• Includes multiple thickness options for incremental tuning and setup refinement
• Lightweight metal construction maintains consistent rotational balance
• Ideal for maintenance, rebuilds, and performance tuning applications
• Supports improved alignment to reduce wear on bearings and shafts over time
