These precision-engineered shims are designed to work with differential assemblies, allowing you to fine-tune your RC car's performance characteristics and adjust differential preload to suit your driving style and track conditions.

Key Features

  • M8 x 13 x 0.4mm Dimensions — These shims are manufactured to precise M8 x 13 x 0.4mm specifications, ensuring they fit correctly into your Losi differential assembly and maintain exact tolerances during operation.
  • Pack of 10 Units — You receive 10 individual shims in this pack, giving you multiple options for tuning your differential preload or building spare setups for your RC vehicles.
  • Genuine Losi OEM Part — These are authentic Losi original equipment manufacturer components, guaranteeing compatibility and quality across all compatible Losi models and ensuring they meet the manufacturer's engineering standards.
  • Differential Preload Tuning — Use these shims to adjust the preload on your differential assembly, which directly affects how your RC car handles corners, accelerates and transfers power to the wheels, allowing you to customise your vehicle's performance characteristics.
  • Durable Construction — Manufactured from quality materials to withstand the demands of RC driving, these shims maintain their dimensions and properties through repeated use and maintain consistent performance throughout their lifespan.
  • Essential Maintenance Component — Whether you're replacing worn shims from your existing differential or building a new assembly from scratch, these components are essential for proper transmission function and longevity.

Technical Performance

The Losi Diff Shim pack represents the level of precision engineering that Losi is known for throughout the RC community. At M8 x 13 x 0.4mm, each shim is machined to exact tolerances that ensure consistent fit and function within your differential assembly. The 0.4mm thickness is a critical specification that allows you to make fine adjustments to differential preload, which is the tension applied to your differential gears. By stacking these shims in different combinations, you can dial in the exact amount of resistance and locking behaviour your differential exhibits, directly influencing how your RC car behaves during acceleration, cornering and gear transitions. The quality of materials used in Losi OEM parts ensures durability even under the demanding conditions of competitive racing or high-speed bashing, and the precision manufacturing means these shims will not wear prematurely or lose their dimensions over time. For anyone serious about maintaining their Losi RC vehicle at peak performance levels, these shims are an essential component of a proper maintenance and tuning programme.

Frequently Asked Questions

  • What are differential shims and why do I need them? — Differential shims are thin spacers that fit into your RC car's differential assembly to adjust preload and control how much the gears lock together. They're essential for tuning your vehicle's handling characteristics and for replacing worn shims during maintenance or rebuilding. Different shim thicknesses allow you to fine-tune how your differential behaves under acceleration and cornering, which directly impacts your RC car's performance.
  • Will these Losi shims fit my RC car? — These M8 x 13 x 0.4mm shims are genuine Losi OEM parts and are compatible with Losi RC vehicles that use this differential specification. To confirm compatibility with your specific model, we recommend checking your vehicle's manual or contacting our expert team at RC Model Shop, where our experienced staff can help identify the correct parts for your setup.
  • How many shims should I use in my differential? — The number of shims you use depends on your specific vehicle setup and your preferred differential behaviour. This varies between different Losi models and driving styles, so refer to your vehicle's manual for recommended specifications, or experiment to find the setup that gives you the handling characteristics you prefer for your driving conditions.
  • Are these shims suitable for both racing and casual bashing? — Absolutely. Whether you're competing in organised RC racing events or enjoying casual weekend bashing around the UK, these Losi differential shims are suitable for all applications and help maintain optimal differential performance across all driving styles and conditions.
  • How often should I replace my differential shims? — Differential shims are durable components, but they can wear over time with heavy use. If you notice your differential preload changing or your vehicle's handling becoming inconsistent, it's time to inspect and potentially replace your shims as part of routine maintenance to restore proper operation.
