Z-ARA330812

Overview

The ARRMA Aluminum Emulsion Shock Cap (2) Z-ARA330812 is an essential replacement suspension component for serious RC enthusiasts across the UK who demand consistent performance from their high-powered RC vehicles. Whether you're running a Kraton 6S or Notorious 6S monster truck, these precision-engineered shock caps are designed to keep your suspension system performing at its peak through countless bashings, races and off-road adventures. As a dedicated RC car UK buyer, you'll appreciate that quality suspension maintenance is the foundation of reliable performance, and these emulsion shock caps represent genuine ARRMA parts that slot seamlessly into your existing setup.

These shock caps aren't just replacements—they're upgrades that enhance the durability and consistency of your RC monster truck or stunt truck. The emulsion design is specifically engineered to maintain consistent performance over repeated suspension cycles, meaning your vehicle will handle the same way run after run, whether you're at the track or enjoying weekend bashing in the park. For RC enthusiasts who want their ready to run RC trucks to perform like built kits, investing in quality suspension components like these makes a tangible difference in handling, predictability and overall driving experience.

Built from lightweight aluminium and finished in stealthy anodised black, these shock caps reduce overall vehicle weight while delivering the durability needed for serious RC action. The package includes everything you need for installation, including rubber upper shock balls, emulsion seals, button head screws and copper bleed screw shims, making this a complete solution for shock cap replacement and maintenance.

Key Features

• High-quality lightweight aluminium construction — The use of aluminium instead of heavier materials reduces your RC vehicle's overall weight, which directly improves acceleration, handling responsiveness and jumping performance, resulting in noticeably better vehicle dynamics whether you're racing or bashing.
• Anodised black finish — The anodised coating provides increased durability and corrosion resistance while delivering that stealthy, professional appearance that serious RC competitors and enthusiasts demand from their suspension components.
• Precision manufactured internal threads — The carefully engineered internal threads ensure that removal and installation are fast and straightforward, saving you time during suspension servicing and maintenance, and preventing the frustration of cross-threaded or damaged components.
• Emulsion design for consistency — The emulsion shock cap design is specifically engineered to deliver increased consistency over repeated suspension cycles, meaning your RC truck will maintain predictable handling characteristics lap after lap, run after run, making it easier to dial in your setup and trust your vehicle's behaviour.
• Complete installation package — Rather than hunting for separate parts, this kit includes rubber upper shock balls, emulsion seals, fasteners and copper bleed screw shims, giving you everything needed for a complete shock cap replacement without additional shopping.

Technical Performance

These ARRMA shock caps represent quality suspension engineering designed for vehicles like the 1/8 scale Kraton 6S and Notorious 6S platforms, which are among the most demanding RC vehicles on the market. The emulsion design is the standout technical feature here—this engineering approach creates a barrier that allows consistent fluid performance across the shock internals, preventing the performance degradation that occurs with standard shock caps over time. The precision-manufactured threads are engineered to tolerances that ensure smooth operation without play or looseness, critical when you're dealing with high-speed impacts and aggressive driving. The lightweight aluminium material has been anodised for durability, ensuring that these components will withstand multiple seasons of use, UV exposure and the occasional impacts that come with off-road RC driving. These shock caps work in conjunction with your existing shock set to maintain proper damping consistency, making them an essential maintenance component that serious RC truck owners in the UK should consider replacing annually or after heavy use. The materials and construction quality here are consistent with genuine ARRMA OEM parts, ensuring compatibility and performance.

Frequently Asked Questions

• Which ARRMA RC trucks are compatible with these shock caps? — These shock caps are confirmed compatible with the ARRMA 1/8 Kraton 6S EXB 4x4 RTR Speed Monster Truck (Black), the Kraton 6S V6 4x4 BLX RTR in Orange, Green, Pink and Blue variants, and the Notorious 6S V6 4x4 BLX RTR in both Black and Blue. If you own one of these high-performance RC monster trucks, these caps are genuine replacement parts that will restore your suspension performance.
• Why would I need to replace shock caps on my RC truck? — Shock caps wear over time due to repeated suspension cycles, UV exposure and impact damage. When caps degrade, they can allow oil seepage, reduce damping consistency and compromise suspension performance. Replacing them is routine maintenance that any serious RC enthusiast should perform annually, especially if you bash hard or race regularly.
• Are these difficult to install? — No. The precision-manufactured internal threads ensure fast and easy removal and installation without requiring special tools. Most RC builders can replace shock caps in under five minutes per corner, making this one of the easiest suspension maintenance tasks you can perform on your RC truck.
• What makes emulsion shock caps better than standard caps? — Emulsion design creates consistent fluid performance across repeated suspension cycles, meaning your truck handles the same way every run. Standard shock caps can degrade and allow inconsistencies that make your vehicle handle differently as you bash throughout the day, whereas these emulsion caps maintain predictability.
• What's included for installation? — The package includes all necessary components: the shock caps themselves, replacement rubber upper shock balls, new emulsion seals, stainless steel fasteners and copper bleed screw shims. This comprehensive approach means you don't need to source parts separately when servicing your shocks.
