Overview
The LOS 5 x 13mm HD Clutch Bearings represent essential maintenance and upgrade components for serious RC enthusiasts in the UK who demand reliability and performance from their machines. These heavy-duty clutch bearings are precision-engineered by Losi, one of the world's most respected names in RC vehicle manufacturing, to deliver consistent performance across a wide range of competitive and recreational RC models. Whether you're a seasoned racer pushing your 1/10 scale buggy to the limit on the track, a truggy pilot tackling off-road terrain, or a motorcycle RC enthusiast operating a high-performance Promoto-MX model, these clutch bearings are designed to handle the demanding conditions that modern RC racing and bashing throw at them.
Clutch bearings are critical components in the drivetrain of any high-performance RC car, truck, truggy or motorcycle. They enable smooth power delivery from the motor to the wheels whilst also allowing the wheels to spin freely when the motor is disengaged or during deceleration. Over time, standard bearings can wear out, losing their smooth operation and introducing friction that robs your RC vehicle of efficiency and speed. That's why upgrading to heavy-duty alternatives like these Losi bearings is a smart investment for anyone serious about getting the best performance from their RC setup. The pack includes two bearings, so you have a spare or can service both sides of your vehicle's drivetrain in one go.
If you're shopping for RC car parts online in the UK, you'll appreciate that these bearings are an OEM (Original Equipment Manufacturer) part, meaning they're genuine Losi components trusted by professional racers and weekend bashers alike. They're compatible with numerous popular Losi models and other RC brands, making them a versatile addition to your spares box. With their proven track record and reputation for quality, these 5 x 13mm clutch bearings are an excellent choice for anyone looking to maintain peak performance or restore their RC vehicle to like-new condition.
Key Features
- Heavy-duty construction — These bearings are specifically designated as HD (heavy-duty) variants, meaning they're built with reinforced materials and tighter tolerances to withstand the intense stresses and vibrations generated during high-speed racing, aggressive bashing, and competitive use. This enhanced durability translates to longer service life and fewer unexpected failures when you need reliability most.
- Precision 5 x 13mm dimensions — The 5mm bore and 13mm outer diameter are precisely engineered to fit perfectly into the clutch assemblies of compatible RC vehicles, ensuring smooth operation without excessive play or binding. This precise fit is critical for optimal power transmission and smooth wheel engagement.
- Pair of bearings included — Each pack contains two bearings, providing you with a complete set to replace both sides of your RC vehicle's clutch system in one purchase, or keep a spare on hand for quick field repairs during races or driving sessions.
- Genuine Losi OEM part — As an official Losi part number LOSA6955, you're purchasing authentic components manufactured to the exact specifications Losi engineers designed for their vehicles, ensuring perfect compatibility and performance characteristics you can rely on.
- Broad compatibility — These bearings are designed to fit a wide range of popular Losi RC models spanning multiple platforms, from entry-level vehicles through to professional competition machinery, making them a versatile choice for builders and bashers with diverse RC collections.
- Performance-focused engineering — The clutch bearing design allows for smooth power delivery and wheel disengagement, enabling your RC vehicle to accelerate smoothly and coast efficiently, which is essential for competitive racing and maximising runtime on a single charge.
Technical Performance
These 5 x 13mm HD clutch bearings represent the culmination of Losi's decades of experience in designing and manufacturing precision RC components. The bearing dimensions of 5mm inner diameter and 13mm outer diameter are carefully calculated to provide the optimal balance between strength, weight and performance for the clutch systems used in modern RC buggies, trucks and motorcycles. The heavy-duty designation indicates these bearings feature premium ball races and hardened steel components that can withstand repeated high-impact engagements and continuous high-speed operation without developing play or looseness. The bearings are designed to work seamlessly with Losi's proprietary clutch systems, facilitating smooth power engagement when accelerating and clean disengagement when coasting, which is vital for competitive lap times and consistent handling characteristics. Whether you're running a Losi 1/4 scale Promoto-MX motorcycle RTR with its high-powered brushless motor, a TLR 1/10 scale 22 5.0 DC buggy on clay tracks, an 8IGHT-XT/XTE truggy, or a 22X-4 elite racing platform, these bearings will maintain the tight tolerances and smooth operation your vehicle demands. The precision manufacturing ensures minimal friction losses, allowing maximum power to reach the wheels efficiently. Replacement or upgrading to these genuine Losi bearings is one of the most cost-effective maintenance steps you can take to restore worn vehicles to peak performance or to future-proof a new purchase against early wear.

Frequently Asked Questions
- What RC models are these clutch bearings compatible with? — These bearings are designed to fit a comprehensive range of Losi RC vehicles including the 1/4 Promoto-MX Motorcycle RTR models (FXR in red and Club MX in blue), the TLR 22 5.0 DC Elite 1/10 scale buggy, the TLR 22X-4 Elite 4WD buggy, and the TLR 1/8 8IGHT-XT/XTE 4WD nitro and electric truggy. Compatibility spans from entry-level recreational models through professional competition platforms, making these bearings useful for enthusiasts with diverse RC collections.
- Why would I need to replace my clutch bearings? — Clutch bearings wear out over time due to the constant stress of engagement and disengagement during RC operation. As they age, they develop excessive play, which causes poor power delivery, inconsistent acceleration, and potential drivetrain damage. High-impact crashes, repeated engagement cycles during racing, and exposure to dirt and moisture can all accelerate bearing wear. Replacing them with fresh heavy-duty bearings restores smooth operation and can significantly improve your RC vehicle's performance characteristics.
- Are these genuine Losi parts or aftermarket alternatives? — These are genuine OEM (Original Equipment Manufacturer) Losi parts, manufactured to the exact specifications Losi engineered for their vehicles. You're not buying generic Chinese bearings or aftermarket copies — you're purchasing authentic components that meet Losi's quality standards and will fit perfectly with original equipment. This authenticity matters when it comes to reliability and performance in competitive or demanding recreational use.
- How many bearings do I need and what do I get in this pack? — Most RC vehicles with clutch systems require two bearings (one for each side of the drivetrain). This pack includes exactly two bearings, so it provides a complete set for a full clutch system replacement. If you're maintaining multiple vehicles or like to keep spares on hand for emergencies, you may want to purchase multiple packs.
- Is this suitable for beginners? — These are maintenance and upgrade components rather than a complete vehicle, so they're intended for RC hobbyists who already own compatible models and have some mechanical experience with RC maintenance. If you're brand new to RC, you'll want to start with a ready-to-run (RTR) vehicle and learn basic operation first. Once you're comfortable with your RC vehicle, learning how to perform bearing replacements and drivetrain maintenance is an excellent next step in the hobby.
- What's the difference between standard and heavy-duty clutch bearings? — Heavy-duty bearings like these feature reinforced ball races, hardened steel components and tighter manufacturing tolerances compared to standard alternatives. This translates to greater durability under stress, longer service life, smoother operation with less friction, and better reliability during aggressive racing or bashing sessions. For competitive use or high-performance applications, the upgrade to HD bearings is well worth the modest additional cost.
