Overview

Transform the suspension performance of your Arrma 3S RC car with the RC Overhaul Big Bore Shock Set in striking red aluminium. Designed specifically for 3S vehicles, this premium shock upgrade delivers a significant improvement over standard factory shocks, making it an essential modification for any RC enthusiast looking to enhance their off-road experience. Whether you're a dedicated basher tackling rough terrain, a weekend racer pushing your limits, or someone discovering the exciting world of RC cars in the UK, this shock set provides the professional-grade performance upgrade you need to take your driving to the next level.

The RC Overhaul Big Bore Shock Set comes fully assembled and ready to install, saving you time and ensuring perfect setup from day one. This complete package includes everything you need to upgrade both the front and rear suspension of your Arrma 3S vehicle, with carefully engineered components that work together to dramatically improve handling, control, and durability. The red aluminium construction gives your RC car a striking appearance whilst delivering the functional benefits of premium shock technology that serious RC car enthusiasts demand.

When you choose this shock set, you're investing in suspension components that have been specifically engineered for Arrma 3S vehicles. The combination of bigger bore shocks, superior materials, and thoughtful design details means you'll notice immediate improvements in how your RC car handles jumps, rough ground, and challenging terrain. This is the kind of upgrade that transforms your RC driving experience, giving you the confidence and control to explore new tracks and push your driving skills further.

Key Features

• Red Aluminium Big Bore Construction — The larger bore diameter of these shocks provides superior dampening characteristics and improved energy absorption compared to standard shocks, which means better control during aggressive driving and more consistent performance across different terrain types.
• Threaded Shock Bodies for Easy Ride Height Adjustment — The threaded design allows you to make precise ride height adjustments without needing additional spacers or complicated modifications, giving you the flexibility to fine-tune your vehicle's stance and performance characteristics for different tracks and driving styles.
• Multi-Hole Pistons for Added Pack — The multi-hole piston design increases the fluid displacement within the shock during compression and extension, creating additional damping force that provides improved stability during take-offs and landings on jumps, which translates to better control and more predictable handling.
• 4mm Shock Shafts for Enhanced Strength — The robust 4mm diameter shock shafts are engineered to withstand the demanding impacts and forces generated during aggressive off-road driving, providing superior durability and reliability compared to thinner shaft designs, which means your shocks will maintain consistent performance even with intense use.
• Included Harder Spring Option — This shock set comes with a harder spring option specifically designed for less demanding off-road use and smoother terrain, allowing you to match your suspension setup to the driving conditions and adjust your vehicle's handling characteristics to suit different environments.
• Pre-Assembled and Ready to Install — These shocks arrive fully assembled and oil-filled, eliminating the need for time-consuming build work and ensuring they're perfectly set up from the moment you open the box, so you can get out and drive immediately.

Technical Performance

The RC Overhaul Big Bore Shock Set represents a significant step up in suspension technology for Arrma 3S vehicles. The bigger bore diameter increases the internal volume available for shock fluid and piston movement, creating a more sophisticated damping curve that responds more effectively to the dynamic forces your RC car experiences during driving. The multi-hole piston design is a critical engineering feature that controls fluid flow through different sized holes, creating variable damping rates that adapt to different speeds of compression and extension. This means the shocks provide firmer support during rapid impacts from jumps whilst remaining compliant during smooth acceleration and cornering. The 4mm shock shafts are a premium specification that significantly reduces flex and ensures consistent performance across repeated impacts. The threaded shock bodies aren't merely a convenience feature—they enable precise height adjustment that affects your vehicle's weight distribution, centre of gravity, and overall handling balance. The front shocks measure 105mm when fully assembled, whilst the rear shocks are 110mm, creating the optimal geometry for Arrma 3S vehicles. The included harder spring set recognises that different driving environments demand different suspension characteristics, giving you the flexibility to optimise performance whether you're driving on smooth surfaces or technical off-road tracks. These shocks are pre-filled with premium shock oil, so you get consistent damping from the first drive without needing to source and measure oil separately.

Frequently Asked Questions

• Will these RC Overhaul big bore shocks fit my Arrma 3S vehicle? — Yes, these shocks are specifically designed for all Arrma 3S vehicles, including popular models such as the Senton 3S and Typhon 3S. The fitment is precise, and the shocks come with all necessary fitting hardware to ensure a straightforward installation. If you're unsure about compatibility with a specific model variant, our expert team at RC Model Shop is happy to confirm before you purchase.
• Do these shocks come pre-filled with oil and ready to use? — Yes, the RC Overhaul Big Bore Shock Set arrives completely assembled and pre-filled with premium shock oil, so there's no additional preparation needed. You can install them and start driving immediately, without needing to purchase separate shock oil or spend time filling and bleeding the shocks yourself.
• Are these an upgrade compared to the standard Arrma 3S shocks? — Absolutely. These RC Overhaul big bore shocks are a significant upgrade over factory standard shocks. The aluminium big bore construction provides superior dampening, the multi-hole pistons offer better control during jumps and impacts, and the 4mm shock shafts are noticeably stronger. Many UK RC enthusiasts who've upgraded to these shocks report dramatically improved handling, better jump control, and increased durability, particularly if your standard shocks have started to leak or lose performance.
• Can I adjust the ride height with these shocks? — Yes, the threaded shock bodies feature fully adjustable ride height, which means you can easily raise or lower your vehicle's stance to fine-tune handling characteristics. This is a key advantage over non-threaded designs and allows you to optimise your Arrma 3S for different tracks and driving styles without purchasing additional components.
• What's the benefit of the multi-hole piston design? — The multi-hole piston creates variable damping by controlling fluid flow through different sized openings. This means the shocks respond differently to slow movements versus rapid impacts, providing better stability and control across a wider range of driving speeds and terrain conditions. During jumps, this design ensures the shocks compress and extend more predictably, giving you better control during landings.
• Are these shocks suitable for beginners learning RC driving? — Yes, these shocks are an excellent upgrade for drivers of all experience levels. Beginners will immediately notice improved handling and more forgiving suspension characteristics, whilst experienced drivers will appreciate the precision tuning options and performance improvements. The big bore design is particularly beneficial for learning because it provides more consistent and predictable suspension behaviour, which makes it easier to understand how your driving inputs affect your vehicle's behaviour.
• Do I need any special tools to install these shocks? — Installation is straightforward and requires only basic RC tools. The shock bodies feature standard mounting points, and all necessary fitting hardware is included in the box. Most users report being able to complete installation in well under an hour, and the process is simple enough for anyone with basic mechanical experience.
• What's the difference between using the standard and harder spring options? — The standard springs (which come installed) work well across a range of driving conditions and provide good balance between comfort and control. The harder spring option, which is included in this set, is optimised for less demanding off-road use and smoother terrain, raising your vehicle's ride height and stiffening the suspension response. You can switch between spring options depending on where you're driving.
