Key Features

• Hard-Anodised Aluminium Bodies — The shock bodies are constructed from premium T6 aluminium with hard-anodised finish, which provides exceptional durability and a factory works aesthetic. Hard anodising creates a protective oxide layer that resists corrosion, impact damage, and wear, ensuring your shocks maintain their performance and appearance for years of bashing and racing.
• PTFE-Coated Shock Bores — The shock cylinders feature PTFE (polytetrafluoroethylene, commonly known as Teflon) coating that reduces friction to nearly zero. This near-frictionless operation means the damping action is instantaneous and responsive, delivering ultra-smooth suspension response that directly translates to better handling and more predictable vehicle behaviour on every terrain.
• Titanium Nitride Coated Shafts — The shock shafts are finished with a premium titanium nitride (TiN) coating that resists scuffing, extends the operational lifespan, and reduces friction throughout the shock's range of motion. This coating protects the critical shaft surfaces from wear caused by the seals and ensures consistent damping performance lap after lap.
• Dual Silicone X-Ring Seals — High-quality silicone X-ring seals provide a perfect seal within the shock body, preventing oil leakage and maintaining consistent damping characteristics. These advanced seals deliver super-smooth performance whilst protecting the internal components from dirt and moisture contamination during outdoor RC driving sessions.
• Progressive-Rate Springs — The shocks are assembled with properly sized progressive-rate springs that match the specifications and rates of stock Slash shocks. Progressive springs provide initial softness for small bumps whilst gradually increasing stiffness to handle larger impacts, giving you versatile suspension performance across varied terrain.
• Optimised Dimensions — Front shocks measure 85mm in length whilst rear shocks are 100mm, perfectly proportioned for the vehicles they're designed for. These specific lengths ensure correct suspension geometry and optimal ride height, which is critical for maintaining proper handling characteristics and vehicle stability.
• 30-Weight Shock Oil Included — Each kit comes filled with pre-mixed 30-weight shock oil, the ideal viscosity for balanced damping in most conditions. The correct shock oil thickness is essential for proper suspension response, and having it included means you can install and drive immediately without additional purchases.
• Ride Height Spacers Included — The kit includes ride height adjustment spacers, allowing you to fine-tune your vehicle's ground clearance and suspension geometry. Adjusting ride height affects handling balance, ground clearance for obstacles, and the overall feel of your RC car, giving you the flexibility to dial in the perfect setup for your driving style.
• Complete Four-Piece Set — You receive two front and two rear shocks in this set, providing a complete suspension upgrade for your Traxxas model. This all-in-one approach means you get matched pairs with consistent performance characteristics across all four corners of your vehicle.
• Machined Aluminium Construction — The shock bodies are precision-machined from solid aluminium billet, ensuring consistent tolerances and perfect bore concentricity. Machining from solid material eliminates weak points that can develop in cast components and ensures each shock performs identically to its partner.

Technical Performance

The Traxxas Big Bore Shocks represent a significant engineering advancement in suspension technology for 1/10 scale RC short course trucks. The larger bore diameter compared to standard shocks allows for greater fluid displacement, which translates to more refined damping characteristics across the full range of suspension travel. The hard-anodised T6 aluminium bodies provide exceptional strength-to-weight ratio, meaning you get robust durability without adding excessive mass to your vehicle. The PTFE-coated shock bores virtually eliminate friction during compression and extension, creating suspension response that feels immediate and responsive to driver input. The titanium nitride coating on the shafts works in conjunction with the X-ring seals to maintain consistent performance even after extended use, resisting the gradual wear that degrades standard shock performance over time. With shock lengths of 85mm front and 100mm rear, these shocks maintain the correct suspension geometry for vehicles like the Slash, Stampede, Rustler, and Nitro Sport, ensuring proper handling balance and ride height characteristics. The included 30-weight shock oil is the industry standard for these applications and provides excellent all-round damping performance. This combination of premium materials, precision engineering, and careful dimensional design creates a suspension component that performs like professional-grade equipment, making it one of the most sought-after upgrades in the UK RC community.

Frequently Asked Questions

• Will Big Bore shocks fit my Traxxas RC car? — Big Bore shocks are compatible with Slash, Stampede, Rustler (both nitro and electric models) and Nitro Sport vehicles. The kit includes springs specifically sized for 2WD Slash models; for other vehicles, you should use the springs that came with your vehicle or consult Traxxas compatibility guides. If you're unsure about compatibility with your specific model, our knowledgeable team can advise you further.
• What makes Big Bore shocks better than standard shocks? — The larger bore diameter allows more sophisticated damping control, whilst the premium materials (hard-anodised aluminium, PTFE-coated bores, titanium nitride shafts) eliminate friction and resist wear far better than standard components. Real-world feedback from UK RC drivers shows these shocks dramatically improve handling, jump control, and overall suspension performance compared to stock setups.
• Do I need to do anything before installing these shocks? — The shocks come fully assembled with 30-weight shock oil already included and springs installed. Installation is straightforward — simply remove your old shocks and bolt these in place. The included spacers allow you to adjust ride height to your preference. No additional shock oil purchases or rebuilding is necessary out of the box.
• Can I adjust the damping on these shocks? — The shocks come pre-filled with 30-weight shock oil, which is the appropriate viscosity for most driving conditions. The progressive-rate springs provide damping characteristics that work well across varied terrain. For advanced tuning, you could experiment with different shock oil weights (lighter for softer response, heavier for stiffer response), but this is optional and not necessary for excellent performance.
• How long do Big Bore shocks last? — The premium materials and precision engineering give these shocks exceptional durability. The hard-anodised aluminium resists damage, the PTFE coating reduces wear on internal components, and the titanium nitride shafts resist scuffing far better than standard shocks.
