Overview
The ARRMA Shock Shaft, 4 x 62mm (2) Z-ARA330706 is an essential suspension spare part designed for serious RC enthusiasts running ARRMA's high-performance 1/10 scale models. Whether you're piloting the Kraton 4X4 4S V2 BLX Speed Monster Truck or the OUTCAST 4X4 4S V2 BLX Stunt Truck, these precision-engineered shock shafts are critical components that keep your RC car UK ready for action. As a dedicated RC model enthusiast, you'll understand that suspension performance directly impacts handling, comfort, and overall driving experience—and these shafts deliver exactly that.
Built with durability and performance in mind, this pair of shock shafts represents ARRMA's commitment to providing quality replacement parts that match the exacting standards of their vehicles. If you've experienced wear on your existing shafts or simply want to keep spare parts on hand for your brushless RC monster truck or stunt truck, this is the genuine OEM solution you need. The two-pack format means you're getting a complete pair, allowing you to refresh both shafts simultaneously for balanced suspension geometry and optimum shock absorber action across all four corners of your vehicle.
RC car spares from ARRMA are trusted by weekend bashers and competitive drivers alike across the UK RC community. These shock shafts are specifically engineered to withstand the demanding forces generated by high-speed running, jumps, rough terrain, and stunt manoeuvres that these vehicles are famous for. Having quality replacement parts like these on hand means you can keep your RC truck in peak condition and ready to run whenever you need it.
Key Features
- Stainless Steel Construction — These shock shafts are manufactured from strong and durable stainless steel, which resists corrosion and degradation even when exposed to water, mud, dust, and other harsh racing conditions that are typical during intensive RC use.
- Precision Manufactured Threads — The threads are precisely engineered to exacting tolerances, allowing for fast and easy servicing, meaning you can remove and reinstall your shocks without frustration or risk of cross-threading or damage to the shafts.
- Polished Shaft Surface — The polished finish on the shaft itself provides a smooth, low-friction interface within the shock absorber body, which translates directly to plush, consistent shock absorber action and smoother suspension movement over bumps and obstacles.
- 4mm Diameter Specification — At 4mm thick, these shafts provide the optimal balance between strength and flex characteristics required for the Kraton and OUTCAST platforms, ensuring they can handle the stresses of extreme off-road driving without bending or breaking under load.
- 62mm Length — The 62mm length is precisely matched to the suspension geometry of the compatible ARRMA models, ensuring correct shock mounting height, suspension travel, and overall vehicle handling characteristics that these vehicles were designed to deliver.
- Two-Pack Format — Supplied as a pair (2 x shock shaft), these shafts allow you to replace both shafts in your vehicle's suspension system simultaneously, maintaining consistent performance and geometry across front and rear suspension or left and right sides.
Technical Performance
The ARRMA Shock Shaft represents the pinnacle of suspension component engineering for 1/10 scale brushless RC trucks. Built from stainless steel rather than softer materials, these shafts deliver exceptional durability during the most extreme action your RC vehicle might encounter. The 4mm diameter provides the precise strength-to-weight ratio that ARRMA's engineers calibrated for their Kraton and OUTCAST vehicles, ensuring the shafts flex appropriately during suspension compression and rebound whilst resisting permanent deformation or failure even after hundreds of jumps and impacts. The polished finish is not merely cosmetic—it reduces friction within the shock absorber barrel, allowing the internal damper fluid to move more freely and the piston rod to travel more smoothly, which directly translates to more responsive and plush shock performance over variable terrain. The precision-manufactured threads ensure that attachment to the shock bodies remains secure over extended use and multiple servicing cycles, and they simplify maintenance procedures that any serious RC enthusiast will perform regularly. At 62mm length, these shafts are engineered to work perfectly within the specific suspension geometry of the ARRMA Kraton 4X4 4S V2 BLX and OUTCAST 4X4 4S V2 BLX models, maintaining the correct ride height, anti-squat characteristics, and overall suspension travel that enables these legendary vehicles to perform at their best whether you're bashing on rough terrain or executing precision stunts.

Frequently Asked Questions
- Which ARRMA models are these shock shafts compatible with? — These shafts are genuine replacement parts for the ARRMA Kraton 4X4 4S V2 BLX Speed Monster Truck and ARRMA OUTCAST 4X4 4S V2 BLX Stunt Truck, including all versions and colour variants of these models. They are the exact same shafts installed at the factory on these vehicles.
- How often should I replace my shock shafts on my RC monster truck? — Shock shafts typically last hundreds of hours of running time, but they should be inspected regularly for signs of wear, pitting, or damage to the polished surface. If you notice reduced shock performance, pitting on the shaft, or bent shafts, replacement is necessary. Many serious racers keep spare shafts on hand to minimise downtime.
- What makes stainless steel shock shafts better than other materials? — Stainless steel offers superior corrosion resistance compared to standard steel or chrome-plated alternatives, making it ideal for RC vehicles used in wet conditions, muddy terrain, or coastal environments. The material also provides consistent performance across a wide temperature range and maintains its polished finish for longer, ensuring plush shock action throughout the life of the component.
- Can I use these shafts on other ARRMA models? — These are specifically designed for the Kraton and OUTCAST 4S V2 BLX models. Whilst other ARRMA vehicles may use similar suspension systems, you should verify compatibility with your specific model before purchasing, as different vehicles may require different shaft diameters or lengths to achieve correct geometry and performance.
- How do I maintain these shock shafts? — Keep the shafts clean and dry when not in use, and inspect them regularly for damage. The polished finish can be maintained by gently wiping with a soft cloth and light oil after washing your RC vehicle. If the shaft becomes pitted or visibly damaged, replacement is recommended to maintain optimal suspension performance.
- Are these genuine ARRMA parts? — Yes, the Z-ARA330706 is the genuine ARRMA part number for these shock shafts, manufactured to original equipment specifications and providing the same quality and performance as the shafts installed on new vehicles.
