Key Features

• Machined Billet Aluminium Body — The shock body is precision-machined from billet aluminium, providing exceptional durability and rigidity whilst keeping weight to a minimum at just 18.7g per shock. This premium material choice ensures the shocks can handle the stresses of rough terrain without flexing or failing, which is essential for serious RC crawler use.
• King Laser-Etched Branding — The top cap and retainer ring feature laser-etched King Off-Road branding, delivering authentic scale detail that enhances the visual realism of your RC build. This level of attention to detail demonstrates that these shocks are designed to look as good as they perform, making them perfect for show builds and competitive crawlers alike.
• Dual Spring Design — The dual spring configuration provides multiple tuning possibilities, allowing you to adjust how your RC car handles different terrain and driving conditions. This flexibility means a single set of shocks can be optimised for various scenarios, from rocky hillsides to technical obstacle courses.
• X-Ring Gaskets for Superior Sealing — X-ring gaskets provide double oil seals within the shock cartridge, dramatically improving oil retention and preventing leakage during extended use. This means your shocks maintain consistent performance longer between maintenance intervals, and the enhanced sealing keeps shock oil where it should be rather than leaking onto your RC chassis.
• Titanium Nitride Coated Shock Shafts — The shock shafts feature a titanium nitride (TiN) coating that significantly reduces friction between the shaft and the seal rings during compression and extension cycles. This coating dramatically improves long-term wearability and extends the service life of the shocks, ensuring they perform smoothly through hundreds of hours of use without degradation.
• Versatile 80mm Length — The 80mm uncompressed length (80mm hole-to-hole measurement) provides flexible installation options across multiple RC crawler platforms. This standardised size fits numerous popular models whilst allowing builders to experiment with different mounting configurations for suspension geometry tuning.

Technical Performance

These RC4WD King Off-Road Racing Shocks represent a significant engineering achievement in scale RC suspension design. The compressed hole-to-hole measurement of 62mm and uncompressed measurement of 80mm deliver an 18mm travel length, providing genuine suspension articulation that helps your RC car absorb impacts and maintain wheel contact over rough terrain. The overall shock length is 90mm, with a shock body outer diameter of 14.6mm and shaft outer diameter of 3.9mm, creating a proportionate and realistic appearance that complements scale crawler builds. Each shock weighs just 18.7g, contributing minimally to your vehicle's overall mass whilst providing substantial functional improvement. The titanium nitride coating on the shock shafts is engineered for exceptional wear resistance, meaning the shocks maintain their smooth operation through countless compression and extension cycles. The X-ring gasket technology, combined with the dual spring design, creates a suspension system capable of handling varied terrain from technical rock crawling to high-speed basher sessions. The shock shafts work in harmony with the precision-machined aluminium bodies to deliver consistent damping characteristics, whilst the white shaft guides and included spacers allow fine-tuning for different vehicle platforms and driving styles. For UK RC enthusiasts, these shocks represent the kind of premium component quality that separates a basic RC car from a purpose-built scale crawler.

Important Setup Information

These shocks arrive without shock oil, which is essential for proper operation. It is highly recommended to build the shocks with silicone shock oil and apply thick shock grease on the X-rings for maximum performance and longevity. The additional X-ring spacers included allow fine-tuning of the shock response. The 2.7mm spacer is pre-installed and provides maximum sealing compression for optimal performance. The 2mm spacer can be substituted if you prefer to allow the shaft to move more freely through the X-rings, offering a softer, less restrictive feel. Experimenting with different spacer combinations enables you to dial in the perfect balance between sealing integrity and shaft movement for your specific driving style and terrain conditions.

Frequently Asked Questions

• Are these shocks suitable for beginner RC crawler builders? — Yes, these shocks are suitable for builders of all experience levels. Whilst they are premium components that will enhance any serious RC crawler, beginners will benefit from their straightforward installation and the included spacers that allow easy tuning. However, you will need to purchase shock oil and grease separately, and basic mechanical knowledge is recommended for installation and tuning.
• What shock oil should I use with these RC4WD King shocks? — Silicone shock oil is specifically recommended for these shocks. The type and weight of silicone oil you choose will affect how firm or compliant the suspension feels. Thicker oils provide more resistance and a firmer feel, whilst thinner oils allow more responsive suspension travel. Start with a medium weight and adjust based on how your RC crawler performs on your local terrain.
• Can I use these shocks on my Traxxas TRX-4? — Yes, these shocks are fully compatible with all Traxxas TRX-4 variants, and the ball ends are a direct fit for Traxxas TRX-4 axle and shock hoop mounts. Installation is straightforward, and the included spacers and shaft guides facilitate quick mounting.
• What is the difference between the 2.7mm and 2mm spacers? — The 2.7mm spacer is pre-installed and provides maximum sealing compression, creating a tighter seal around the shock shaft with increased resistance to oil leakage. The 2mm spacer allows more freedom of movement for the shaft through the X-rings, which can result in a slightly more responsive and less restrictive suspension feel. You can experiment with both to find the tuning that works best for your RC car and driving style.
• Are these shocks better than standard shocks for my RC crawler? — These RC4WD King Off-Road Racing Shocks offer several significant improvements over basic shocks. The titanium nitride coated shafts provide superior wear resistance, the X-ring gaskets offer better oil retention than standard o-rings, the dual spring design enables suspension tuning, and the billet aluminium construction delivers exceptional durability. These features combine to provide noticeably improved performance and longevity compared to standard shock options.
• How do the X-ring gaskets improve performance? — X-ring gaskets have a unique cross-sectional design that provides two contact points with the shock shaft instead of the single contact point of traditional o-rings. This double sealing design dramatically reduces oil leakage, maintains consistent damping characteristics throughout the shock's service life, and extends the maintenance intervals required.
• Can these shocks be used on an Axial SCX10-3? — Yes, these shocks can be installed on an Axial SCX10-3. However, the installation notes recommend using a 5mm black spacer with an M3 hole (Z-S0821) on the shock tower to ensure proper fitment and alignment with your Axial platform.
