If you're experiencing worn shocks, bent components, or simply want to upgrade your suspension setup, this shock set provides a straightforward solution that requires minimal technical knowledge to install.

This is not an aftermarket alternative — these are the genuine ARRMA suspension components that your RC car was designed to use. Built with premium materials and precision engineering, the 117mm shock length with 8x1.2 piston configuration and 1300cSt oil viscosity offers the ideal balance of responsiveness and stability for aggressive driving and competitive racing alike.

Key Features

• High-quality anodised aluminium shock bodies — The shock bodies are machined from premium anodised aluminium, providing excellent corrosion resistance and lightweight strength that won't add unnecessary weight to your RC suspension while maintaining structural integrity through countless runs and impacts.
• Anodised shock caps and shock seal caps — These protective caps maintain the integrity of the shock assembly and prevent dust, dirt and moisture from entering the shock body, which is essential for maintaining performance in wet UK weather conditions and dusty off-road environments.
• Preload adjusters included — The integrated preload adjusters allow you to fine-tune your suspension setup to match different driving conditions, track surfaces and personal preferences, giving you the flexibility to optimise handling without purchasing additional components.
• Strong 4mm stainless steel shock shafts — The thick 4mm stainless steel shafts provide exceptional durability and resistance to bending, ensuring your shocks maintain their geometry through aggressive bashing, jumping and competitive racing where lesser shafts would fail.
• Tough composite shock rod ends — The composite rod ends offer an excellent balance of weight savings and strength, reducing unsprung mass whilst providing reliable service life through repeated compression and extension cycles.
• Composite spring retainers — These retainers keep your springs securely positioned whilst minimising weight, allowing for precise spring preload adjustment without the limitations of heavier metal alternatives.
• Supplied completely assembled — Save time and frustration with factory-assembled shocks that arrive ready to install, eliminating the need for shock assembly tools, expertise or the risk of improper assembly that could compromise performance.
• Pre-filled with 1300cSt silicone shock oil — The shocks arrive filled with precisely specified 1300cSt silicone shock oil, meaning you can bolt them straight onto your vehicle without the mess and hassle of oil changes, immediately enjoying optimal damping characteristics.
• Ready to bolt on after spring fitting — Simply install your choice of spring to match your driving style and track conditions, then bolt the complete shock assembly to your vehicle — no additional tools or expertise required.
• Shock boots included for protection — The included shock boots protect the shock shafts from dirt, mud and moisture ingress, extending the service life of the internal components and maintaining consistent damping performance even in wet or muddy conditions typical of UK off-road driving.

Technical Performance

The ARRMA Shock Set represents professional-grade suspension engineering optimised for a 117mm shock length, which provides the appropriate amount of suspension travel for balanced handling across a wide range of driving conditions. The 8x1.2 piston configuration determines the internal flow characteristics of the damper, affecting how quickly the oil passes through the piston during compression and extension, directly influencing how the vehicle responds to bumps, jumps and cornering forces. The 1300cSt oil viscosity is a carefully calibrated specification that provides the ideal balance of responsiveness during quick movements whilst offering sufficient damping to control oscillation and maintain stability during sustained driving. This combination has been engineered and tested by ARRMA to deliver predictable, controllable handling that works across various ARRMA models including the BIG ROCK 6S 4x4 RTR Brushless Monster Truck. The 4mm stainless steel shafts represent premium engineering for the RC scale, offering substantially greater rigidity and durability than thinner alternatives, which means your shocks will maintain consistent performance session after session without developing the annoying shaft flexing that leads to unpredictable handling. The anodised aluminium construction provides both lightweight strength and superior corrosion resistance compared to painted steel, ensuring your shocks won't rust or degrade when exposed to damp British weather, salt water exposure during coastal bashing sessions, or the inevitable muddy conditions encountered at UK RC tracks and off-road venues. Whether you're competing in time trials, enjoying casual weekend bashing with friends, or putting your RC car through serious punishment at racing events, these OEM suspension components deliver the reliability and performance you've come to expect from ARRMA.

Frequently Asked Questions

• What RC cars are these shocks compatible with? — These ARRMA shocks with 117mm length, 8x1.2 piston and 1300cSt oil specification are designed as genuine OEM components for ARRMA vehicles including the 1/7 BIG ROCK 6S 4x4 RTR Brushless Monster Truck. Always verify fitment with your specific model before purchase, as shock specifications vary across different ARRMA scales and designs.
• Do these shocks arrive pre-filled with oil? — Yes, these shocks are supplied completely assembled and pre-filled with high-quality 1300cSt silicone shock oil, which means you can install them immediately without needing to change oil or perform any assembly work, saving you time and ensuring proper oil viscosity from the moment you install them.
• Can I adjust the performance of these shocks after installation? — Yes, the included preload adjusters allow you to fine-tune how the springs sit and how the suspension compresses, enabling you to optimise handling for different track conditions, driving styles and vehicle setups without purchasing additional components.
• Are these shocks suitable for competitive racing? — Absolutely. These are genuine ARRMA OEM suspension components manufactured to the exact specifications required for both casual driving and competitive racing, providing the reliability and consistent performance that serious RC enthusiasts demand at the track.
• Why should I replace my shocks with these OEM parts rather than aftermarket alternatives? — OEM ARRMA shocks are engineered specifically for your vehicle and guarantee perfect fitment, proper suspension geometry and optimal performance characteristics that work together with all other suspension and chassis components, whereas aftermarket alternatives may not account for all these factors and could compromise handling consistency.
• What is shock oil viscosity and why does the 1300cSt specification matter? — Shock oil viscosity measures how thick and resistant to flow the oil is; 1300cSt (centistokes) is the precisely specified thickness for these shocks that determines damping rate, handling responsiveness and how well the shocks absorb impacts, and using the correct specification ensures your vehicle handles exactly as the engineers intended.
• Are these shocks waterproof for wet weather UK RC driving? — The shocks feature anodised aluminium bodies and seal caps that provide excellent protection against moisture and dirt ingress, with shock boots included to further protect the shafts, making them suitable for damp British weather conditions, muddy tracks and coastal environments.
• How long do these shocks typically last? — With proper maintenance and the included shock boots fitted to protect the shafts, these durable aluminium and stainless steel components should provide many seasons of reliable service, though internal seals will eventually wear with heavy use and may require replacement over time.
