Key Features

• Precision Manufactured Aluminium Slipper Hub — The slipper hub is manufactured to exacting tolerances from high-quality aluminium, providing a lightweight yet rigid foundation that efficiently transfers drive to the rear transmission without flex or play. This precision construction ensures consistent performance lap after lap and ensures long-term durability even under extreme driving conditions.
• Durable Composite 55 Tooth 0.8 Module Spur Gear — The composite spur gear is engineered specifically for reliable power handling capability, with its 55-tooth configuration and 0.8 module specification providing the exact gear ratio required for optimal performance. The composite material offers excellent durability while remaining lightweight, making it an ideal choice for RC cars that need both strength and responsive acceleration characteristics.
• Castellated Slipper Pad Design — The castellated (notched) slipper pad features assured location into the spur gear, meaning it locks securely in place without risk of rotation or misalignment during operation. This precision-engineered feature eliminates performance inconsistencies caused by pad slippage and ensures predictable slipper engagement every single time you drive.
• Red Anodised Aluminium Slipper Shaft — The slipper shaft is constructed from strong red anodised aluminium, offering both visual appeal and exceptional durability. The anodised finish provides enhanced corrosion resistance, whilst the aluminium construction keeps weight to a minimum, contributing to improved overall vehicle performance and handling characteristics.
• Molded Composite Tension Nut — A molded composite nut allows you to easily adjust and set the spring tension for consistent slipper settings, giving you the ability to fine-tune your slipper engagement characteristics to match your driving style and the conditions you're racing in. This adjustability ensures optimal performance across various driving scenarios.
• Fully Assembled and Pre-Set — Perhaps the most significant advantage of this slipper set is that it arrives completely assembled and factory-set, ready to install directly into your vehicle. This eliminates the need for complex assembly procedures and initial calibration, making it an excellent choice for RC enthusiasts who want to upgrade their drivetrain quickly and efficiently.

Technical Performance

The ARRMA 55T Slipper Set represents the pinnacle of drivetrain component engineering, combining precision-manufactured aluminium components with durable composite materials to create a slipper clutch system that reliably protects your transmission whilst delivering smooth, consistent power delivery. The 55-tooth, 0.8 module composite spur gear is specifically calibrated to handle the demands of high-performance RC car driving, providing excellent power transmission efficiency without sacrificing durability or responsiveness. The precision aluminium slipper hub takes drive to the rear transmission with minimal friction loss, ensuring that engine or motor power is efficiently converted into forward motion. The engineering of this slipper set reflects ARRMA's deep understanding of RC drivetrain dynamics, with each component precisely sized and shaped to work in perfect harmony. The red anodised aluminium shaft provides structural rigidity whilst the castellated slipper pad ensures absolute positional accuracy under all driving conditions. The molded composite tension nut allows precise adjustment of spring tension, giving experienced RC drivers the ability to optimise slipper engagement characteristics for their specific vehicle setup and driving preferences. Whether you're running this in competitive racing environments or during aggressive weekend bashing sessions, the robust construction and precision engineering ensure reliable performance across a wide range of operating conditions.

Frequently Asked Questions

• What is a slipper clutch and why do I need one in my RC car? — A slipper clutch is a critical drivetrain component that protects your RC car's transmission and gears from damage during hard impacts and sudden deceleration. When your RC vehicle experiences a significant shock or sudden stop, the slipper clutch allows the spur gear to slip relative to the hub, preventing the transmission and differential gears from experiencing catastrophic damage. This protection is essential for maintaining the longevity of your RC car's drivetrain, particularly if you drive aggressively or in rocky terrain where impacts are frequent.
• Is this slipper set suitable for my RC car model? — The ARRMA 55T Slipper Set is specifically designed for ARRMA RC vehicles that utilise a 0.8 module drivetrain system. Before purchasing, you should verify that your ARRMA model uses 0.8 module components and requires a 55-tooth spur gear. Consult your vehicle's manual or contact the retailer to confirm compatibility with your specific RC model.
• What does the 55T and 0.8 Mod specification mean? — The 55T specification refers to the spur gear having 55 teeth, which directly impacts the gear ratio and therefore the acceleration and top speed characteristics of your RC car. The 0.8 Mod designation indicates the module size of the gear teeth, which determines the physical size and spacing of the teeth on the spur gear. These specifications must match your vehicle's existing drivetrain components to ensure proper fit and function.
• Is this product ready to install immediately? — Yes, the ARRMA 55T Slipper Set arrives completely assembled and pre-set at the factory. You can install it directly into your RC vehicle without needing to perform any assembly procedures or initial calibration, making it an excellent choice for users who want to upgrade their drivetrain quickly and conveniently.
• Can I adjust the slipper engagement if needed? — Yes, the molded composite tension nut allows you to adjust the spring tension and therefore the slipper engagement characteristics if needed. However, the set arrives pre-set from the factory, and most users will find that the factory settings work perfectly without requiring adjustment. If you do wish to adjust the slipper tension, consult your vehicle's manual for specific guidance on making these adjustments safely.
• What materials is this slipper set constructed from? — The slipper set combines precision-manufactured red anodised aluminium for the slipper hub and shaft with durable composite materials for the 55-tooth spur gear and the tension nut. This combination of materials provides an excellent balance between weight savings, durability, and precision engineering.
