This hard-duty specification ensures you get the durability needed for competitive racing, weekend bashing, or technical crawling challenges that demand precision engineering and reliability.
Compatible with multiple Losi models including the CCR (Competition Crawler), NCR (Night Crawler), and NCR SE (Night Crawler Special Edition), this replacement part is a must-have addition to any Losi crawler owner's spares collection. Keeping genuine replacement parts on hand means you can quickly get back to racing or crawling without extended downtime, and you'll have the confidence that your drivetrain is operating with factory-correct components designed specifically for your model.
Key Features
- CV Pin Retainer Clip Design — The retainer clip is engineered to securely hold the constant velocity pins in place, preventing unwanted movement or separation during aggressive driving or technical rock crawling that puts extreme stress on the drivetrain components.
- 11mm Pins Included — This kit comes complete with the 11mm diameter pins that work alongside the retainer clip to create a robust CV joint assembly, eliminating the need to source additional components separately.
- Hard-Duty Specification — Designated as an HD (heavy-duty) component, this part is built to withstand the rigorous demands of competition crawling, rough terrain negotiation, and intensive off-road use that typical crawler components must endure.
- Genuine OEM Losi Part — As an official Losi replacement component, you can be confident this part meets the exact manufacturing specifications and quality standards that Losi designed for your specific crawler model, ensuring perfect fitment and performance.
- Multi-Model Compatibility — Engineered to work across the Losi CCR, NCR, and NCR SE crawler range, this single replacement part provides versatility across multiple models within the Losi crawler family, making it an excellent addition to any multi-model collection.
- Drivetrain Reliability — By replacing worn or damaged CV pin retainers and pins, you restore full drivetrain integrity and eliminate slack or play that could compromise handling precision, traction response, and overall vehicle control during competitive events or technical driving.
Technical Performance
The CV Pin Retainer Clip & 11mm Pins HD represents precision engineering at the drivetrain level where power delivery and mechanical reliability directly impact your RC crawler's performance. The constant velocity joint is one of the most critical components in any crawler's drivetrain, responsible for transferring rotational force from the motor and transmission assembly through to the wheels whilst accommodating suspension articulation and steering angles. The 11mm pins are precision-manufactured to exact tolerances, ensuring they fit securely within the CV joint components without excessive play or lateral movement. The retainer clip is engineered from durable materials capable of withstanding the compressive and shear forces generated during aggressive driving, particularly during high-stress manoeuvres like climbing near-vertical obstacles or executing sharp directional changes on uneven terrain. The hard-duty (HD) specification of this component indicates it has been reinforced or manufactured from higher-grade materials compared to standard versions, providing enhanced resistance to wear, deformation, and fatigue failure. This is particularly important for competition crawler operators who subject their vehicles to extreme articulation angles and sustained high-load conditions. Whether you're replacing components after wear from heavy use, upgrading to hard-duty specifications for increased reliability, or simply maintaining your Losi crawler with genuine replacement parts, this CV pin assembly ensures your drivetrain remains in optimal working condition and delivers consistent, predictable power delivery from motor to wheels.

Frequently Asked Questions
- Which Losi crawler models is this CV Pin Retainer Clip compatible with? — This OEM Losi part is specifically engineered for the Losi CCR (Competition Crawler), NCR (Night Crawler), and NCR SE (Night Crawler Special Edition) models. Always verify your specific model number before purchasing to ensure compatibility with your crawler.
- What is a CV pin retainer and why do I need to replace it? — The CV pin retainer clip holds the constant velocity pins securely in the CV joint, a critical drivetrain component. Over time, these pins and retainers can wear, become damaged, or deform under the extreme stresses of rock crawling and competition use. Replacing them restores proper CV joint function, eliminates drivetrain slack, and maintains precise power delivery to your wheels.
- What does the HD (heavy-duty) specification mean for this component? — The HD designation indicates this is a reinforced, hard-duty version designed to withstand more aggressive use and higher stress loads compared to standard components. If you're running your Losi crawler competitively or pushing it hard over extreme terrain, the HD specification provides enhanced durability and reliability.
- Is this a genuine Losi OEM part? — Yes, this is an official Losi replacement part manufactured to OEM specifications. Using genuine Losi parts ensures perfect fitment, proper performance characteristics, and reliability you can depend on, making it the correct choice for maintaining your crawler at factory standards.
- How often should I replace the CV pins and retainer clip? — Replacement frequency depends on your usage intensity, terrain difficulty, and driving style. Competition drivers and those pushing their crawlers through extreme rock gardens may replace these components more frequently than casual weekend users. Inspect regularly for wear, and replace if you notice drivetrain play, binding, or reduced power delivery.
- Can I use this part on other Losi models? — This part is specifically designed for the CCR, NCR, and NCR SE crawler models. Do not use on other Losi vehicles without confirming compatibility, as CV joint designs vary significantly across different model platforms.
