Overview
The ARRMA Steel 57T Slipper Set, 0.8Mod is a high-performance transmission component engineered for serious RC enthusiasts in the UK who demand reliability and durability from their brushless RC models. Whether you're running a 1/10 scale monster truck, short course truck, stadium truck, or 1/8 scale buggy, this precision-manufactured slipper clutch assembly is designed to handle maximum power whilst protecting your drivetrain from catastrophic damage. This ready-to-install slipper set comes fully assembled and pre-set, meaning you can drop it straight into your ARRMA RC car without fiddling with complex adjustments or additional setup procedures.
Slipper clutches are absolutely critical components in modern high-performance RC vehicles. They work by allowing controlled slippage between the spur gear and the vehicle's motor during extreme acceleration or when the wheels lose traction, preventing the transmission from jamming or stripping gears. The ARRMA Steel 57T Slipper Set represents premium quality engineering and is recognised as a standard part across a wide range of ARRMA's most popular ready to run RC models, from the legendary KRATON 4S and OUTCAST 4S speed trucks to the GRANITE and SENTON monster trucks, making it an essential upgrade or replacement for maintaining peak drivetrain performance.
Built with precision-engineered aluminium slipper hubs and a high-strength 57-tooth steel spur gear, this transmission component is purpose-built for delivering consistent performance lap after lap, whether you're bashing at the local track or pushing your RC buggy or truck to the limit. The assembly includes stainless steel components and castellated slipper pads engineered for assured location and positive engagement with the spur gear, ensuring smooth, predictable power delivery every single time you throttle up.
Key Features
- Precision Manufactured Aluminium Slipper Hubs — The slipper hubs are precision-engineered from high-quality aluminium alloy, delivering an optimal balance between weight savings and structural rigidity, which is essential for maintaining consistent clutch engagement across varying levels of throttle input and driving conditions.
- High Strength 57T 0.8 Module Steel Spur Gear — The spur gear is manufactured from high-strength steel in a 57-tooth configuration with 0.8 module specification, providing maximum power handling capability and resistance to tooth stripping, making this component suitable for both brushless electric motors and demanding driving styles across multiple ARRMA vehicle platforms.
- Castellated Slipper Pads for Assured Location — The castellated (notched) design of the slipper pads ensures they remain positively located within the spur gear at all times, preventing unwanted movement or slippage during engagement, which guarantees smooth and predictable clutch operation during acceleration and deceleration.
- Stainless Steel Slipper Plate — The slipper plate is manufactured from stainless steel, providing superior corrosion resistance and durability, which is particularly important for UK RC drivers who may encounter wet or humid conditions during outdoor racing and bashing sessions.
- Fully Assembled and Pre-Set — This slipper set arrives completely assembled and pre-adjusted, eliminating the need for time-consuming setup, detailed clutch adjustments, or additional tuning before installation into your RC vehicle, making it the perfect solution for quick repairs, upgrades, or maintenance between races.
- Broad Vehicle Compatibility — The ARRMA Steel 57T Slipper Set is a standard part across multiple ARRMA vehicle lines including the BIG ROCK 3S, GRANITE 3S and 4X4, KRATON 4S, OUTCAST 4S, SENTON 3S and 4X4, VORTEKS 3S, TYPHON 3S, and GRANITE BOOST and SENTON BOOST models, providing flexibility and ensuring you can maintain consistent drivetrain specifications across multiple RC trucks and buggies.
Technical Performance
The ARRMA Steel 57T Slipper Set represents the pinnacle of RC transmission engineering, combining precision-manufactured components with robust material selection to deliver exceptional durability and performance. The 0.8 module specification denotes the gear pitch and module size, which is a standard measurement in RC drivetrain engineering that ensures compatibility across ARRMA's extensive model range. The 57-tooth spur gear configuration strikes an ideal balance between acceleration and top-end speed capability, whilst the high-strength steel construction provides outstanding resistance to tooth wear and stripping during sustained high-speed runs or aggressive acceleration. The aluminium slipper hubs offer excellent dimensional stability and lightweight construction, contributing to responsive handling characteristics and reduced rotating mass, which translates to quicker acceleration and more efficient power delivery from your brushless electric motor. The stainless steel slipper plate resists corrosion and oxidation far more effectively than standard steel, making it particularly suited to the UK climate where moisture exposure is common. The castellated slipper pads feature a notched profile that physically prevents the pads from rotating within the spur gear teeth, eliminating a common failure mode in lesser-quality clutch systems. This entire assembly is designed to work seamlessly with the high torque outputs of modern brushless RC systems, protecting your drivetrain whilst maintaining the responsive throttle control and rapid acceleration that serious RC drivers demand. Whether you're operating a 3S, 4S, or 8S LiPo-powered vehicle, this slipper clutch is engineered to handle the power delivery without slipping excessively or allowing gear damage during extreme driving conditions.

Frequently Asked Questions
- What is a slipper clutch and why do I need one in my RC vehicle? — A slipper clutch is a transmission component that allows controlled slippage between the motor and the spur gear when extreme acceleration or wheel slip occurs, preventing gear jamming and tooth stripping. Without a quality slipper clutch, your drivetrain would be at constant risk of catastrophic damage during aggressive driving, making it an essential component for any high-performance brushless RC truck or buggy.
- Is this slipper set suitable for beginners? — Yes, this is an excellent choice for beginners because it arrives fully assembled and pre-set, requiring no complex adjustment or tuning before installation. Simply remove your old slipper clutch and drop this one in. However, beginners should understand that slipper clutches are replacement and maintenance parts rather than components that add extra capability to a base vehicle; they maintain the performance envelope of vehicles that already have slipper clutches fitted from the factory.
- What models does this Steel 57T Slipper Set fit? — This slipper set is a standard part across a broad range of ARRMA vehicles including the 1/10 BIG ROCK 3S, GRANITE 3S and 4X4, KRATON 4S, OUTCAST 4S, SENTON 3S and 4X4, VORTEKS 3S, GRANITE BOOST 2WD, SENTON BOOST 2WD, VORTEKS BOOST 2WD, and the 1/8 TYPHON 3S 4X4 buggy. It is listed as a standard part for these models, meaning it comes fitted from the factory and can be purchased as a direct replacement or upgrade.
- What is the difference between the 57T and other tooth counts? — Tooth count affects your vehicle's gearing ratio and overall performance characteristics. A 57-tooth spur gear provides a balanced setup suitable for mixed driving conditions. Larger tooth counts (60T+) provide slightly more top speed but less acceleration, whilst smaller tooth counts (below 55T) offer more acceleration but lower maximum speed. The 57T is optimised for the broad range of ARRMA vehicles it fits, offering excellent all-around performance.
- Can I use this on a ready to run RC truck from RC Model Shop? — If you own an ARRMA ready to run RC model listed in the compatibility chart above, this slipper set is the correct replacement or upgrade component. However, it is specifically engineered for ARRMA vehicles and would not be compatible with other manufacturers' RC cars without significant modification.
- How long does a slipper clutch last? — Slipper clutch lifespan depends on driving intensity, maintenance, and how aggressively the vehicle is used. Regular inspection of the slipper pads and plate for wear is recommended. When pads become significantly worn or the clutch begins slipping excessively during normal driving, replacement is straightforward thanks to the fully assembled, ready-to-install design of this set.
