Overview
The ARRMA Shock Set Bore:20mm, Length:178mm, Oil:700cSt (Z-ARA330748) is a precision-engineered suspension component designed specifically for the ARRMA Kraton 8S EXB brushless monster truck. This assembled shock set represents a genuine OEM replacement part, perfect for RC enthusiasts in the UK who demand reliability and performance from their RC car UK setup. Whether you're replacing worn suspension components or upgrading your off-road RC vehicle, this shock set delivers the durability and engineering quality that ARRMA is recognised for in the RC hobby community.
Manufactured to exacting standards, these shocks feature red anodised aluminium bodies combined with smooth polished stainless steel shock shafts, creating a suspension system built to withstand the rigours of bashing and racing. The complete assembled design means you can have your RC monster truck back in action quickly, simply by fitting your choice of springs and bolting the shocks onto your vehicle. This is an essential component for any serious RC enthusiast who wants to maintain peak suspension performance.
These replacement shocks come pre-assembled and pre-filled with 700cSt silicone shock oil, eliminating the need for complex setup procedures. The heavy-duty construction and 6mm thick shock shafts ensure exceptional durability during aggressive driving conditions, making this shock set ideal for both weekend bashers and competitive RC drivers who want reliable, consistent suspension performance from their brushless RC truck.
Key Features
- Red Anodised Aluminium Shock Bodies — The precision-manufactured aluminium construction provides excellent strength-to-weight ratio whilst the red anodised finish offers both aesthetic appeal and corrosion resistance, ensuring your suspension components maintain their appearance and structural integrity through countless drives.
- 6mm Thick Shock Shafts — The heavy-duty shock shafts are engineered for maximum durability and resistance to bending or damage during aggressive driving, giving you confidence that your suspension will handle hard impacts and challenging terrain without failure.
- Smooth Polished Stainless Steel Shafts — The precision-polished stainless steel construction reduces friction and wear, allowing smooth suspension movement and extending the lifespan of your shock components compared to standard finishes.
- Heavy Duty Rod Ends — The robust composite rod ends are designed to withstand the stresses of high-speed driving and rough terrain, providing secure connection points that won't wear prematurely or cause suspension binding.
- Pre-Filled with 700cSt Silicone Oil — Each shock arrives pre-filled with premium 700cSt silicone shock oil, delivering consistent damping performance from the moment you install the shocks, eliminating guesswork and compatibility issues.
- 8 Hole 1.4mm Shock Pistons — The precisely engineered shock pistons with eight 1.4mm orifices provide optimised fluid flow for balanced damping characteristics, ensuring your RC car handles both bumps and cornering with predictable, responsive suspension behaviour.
- Tough Composite Molded Parts — The durable composite components are impact-resistant and lightweight, withstanding the demands of off-road driving whilst contributing to overall vehicle performance and handling characteristics.
- Threaded Spring Preload Adjusters — Included spring preload adjusters allow you to fine-tune your vehicle's ride height and suspension stiffness without requiring additional tools or aftermarket parts, giving you control over your RC monster truck's setup.
- Ready to Bolt On — These shocks are supplied fully assembled and only require springs to be fitted before installation, saving you hours of assembly time and getting your brushless RC truck back on the track or bash course quickly.
- Pair of Two Shocks — The set includes two complete 178mm shock absorbers, providing a matching pair for consistent front and rear suspension performance on your ARRMA vehicle.
Technical Performance
The ARRMA Z-ARA330748 shock set represents premium suspension engineering specifically calibrated for the Kraton 8S EXB, a high-performance brushless monster truck designed for demanding off-road conditions. At 178mm in length with a 20mm bore diameter, these shocks are engineered to provide optimal damping and ride quality for a 1/5 scale vehicle platform. The 6mm thick shock shafts are significantly more robust than standard alternatives, offering superior resistance to lateral loads and impact forces encountered during aggressive driving. The combination of red anodised aluminium bodies and polished stainless steel shafts creates a suspension system that not only performs exceptionally but also resists corrosion and maintains its finish through repeated exposure to moisture and dirt common in UK driving conditions. Pre-filled with 700cSt silicone shock oil, these shocks deliver consistent damping characteristics that complement the brushless power delivery of modern RC vehicles. The 8-hole 1.4mm piston design has been optimised for the Kraton 8S platform, ensuring smooth compression and rebound whilst maintaining predictable handling through both high-speed runs and technical crawling sections. Heavy-duty composite rod ends distribute suspension loads effectively, preventing wear and maintaining precise connection geometry essential for accurate vehicle handling. Whether you're enjoying weekend bashing at your local RC club in the UK or pushing your brushless RC truck to the limit in competitive environments, these shocks provide the engineering quality and performance reliability that serious RC enthusiasts demand.

Frequently Asked Questions
- What ARRMA vehicles are these shocks compatible with? — These Z-ARA330748 shocks are specifically designed for the ARRMA Kraton 4X4 8S BLX EXB brushless monster truck (model C-ARA5808V2T1). Always verify compatibility before purchasing replacement suspension components for your RC vehicle.
- Do I need to do anything before using these shocks? — The shocks arrive fully assembled and pre-filled with 700cSt silicone shock oil, so they're ready to use. You only need to fit your chosen springs using the included threaded preload adjusters, then bolt them onto your vehicle.
- What springs should I use with these shocks? — ARRMA supplies three recommended spring options: ARA330572 (2.54N/mm for heavier setups), ARA330616 (2.15N/mm for general use), and ARA330617 (2.41N/mm for balanced performance). Choose based on your driving style and terrain conditions.
- How do the threaded spring preload adjusters work? — The adjusters allow you to fine-tune your vehicle's ride height by changing how much the springs are compressed when the vehicle is at rest. This enables you to optimise suspension geometry and handling balance without requiring different springs.
- Are these genuine ARRMA parts? — Yes, these are authentic OEM ARRMA replacement shocks, manufactured to the same exacting standards as components supplied in new ARRMA vehicles. When you purchase from RC Model Shop as an authorised dealer, you can be confident you're receiving genuine products.
- What makes these shocks better than aftermarket options? — These shocks are specifically engineered for the Kraton 8S EXB platform, with the piston design, oil viscosity, and damping characteristics optimised for that vehicle's geometry and performance envelope. The 6mm thick shafts and heavy-duty rod ends provide durability beyond many aftermarket alternatives.
- Can I use these shocks on other ARRMA vehicles? — These shocks are compatible specifically with the Kraton 4X4 8S BLX EXB. Other ARRMA vehicles may use different shock sizes or specifications, so always verify compatibility before purchasing. Check your vehicle's specifications or contact our expert team for guidance.
