Overview
The ARRMA Aluminum Shock Cap in Black (2) is an essential suspension spare part designed for RC car enthusiasts across the UK who demand reliability and precision in their setups. Whether you're a dedicated basher pushing your RC model to the limit on weekends or a competitive racer fine-tuning every component for maximum performance, these shock caps represent a genuine upgrade over standard components. ARRMA is a recognised leader in the RC hobby industry, and their commitment to engineering excellence is evident in every detail of these precision-manufactured caps.
These replacement shock caps are engineered for anyone who wants to maintain their RC car in peak condition. If you've damaged your existing shock caps through heavy use, want to refresh your suspension setup, or are building a custom RC vehicle configuration, these lightweight aluminium alternatives deliver exactly what you need. The black anodised finish not only looks stealth and professional on your RC model but also provides real durability benefits that keep your investment protected for longer.
As a suspension spare part, the shock cap plays a crucial role in your RC car's performance. It secures the shock shaft and helps maintain consistent suspension geometry, which directly impacts handling, stability and overall drivability. Having quality replacement caps on hand means you're never stuck waiting for repairs—you can service your shocks quickly and get back to enjoying your RC hobby.
Key Features
- High-quality lightweight aluminium construction — These caps are manufactured from premium aluminium alloy that significantly reduces vehicle weight compared to plastic alternatives, which means better acceleration, improved handling and more consistent performance across all driving conditions. Lighter components translate directly to faster lap times and more responsive steering on your RC model.
- Anodised black finish for increased durability — The anodised coating provides a protective layer that resists corrosion, scratches and general wear from regular use, ensuring your shock caps maintain their professional appearance and structural integrity even after months of intense bashing or racing. The stealth black aesthetic also gives your RC car a premium, competition-ready look.
- Precision manufactured internal threads — Every thread is engineered to exact specifications, meaning when you need to service your shocks, removal and installation is fast, easy and frustration-free. Poor-quality threads can strip easily or cause installation problems; these precision threads ensure consistent fit every time you service your suspension.
- Supplied as a pair — You receive two shock caps, giving you a complete front or rear suspension upgrade, or allowing you to refresh both sides of your RC vehicle's suspension in one purchase without needing to buy multiple sets.
Technical Performance
These aluminium shock caps are engineered with precision manufacturing processes that ensure dimensional accuracy and consistent performance. The internal threading is machined to tight tolerances, preventing the loose fits and binding issues that can arise from inferior spare parts. The lightweight aluminium material (anodised for protection) delivers measurable performance benefits—every gram of weight reduction at the suspension improves weight distribution and responsiveness in your RC car. The anodised black finish isn't merely cosmetic; it's a genuine protective treatment that resists oxidation and provides durability characteristics that standard painted finishes cannot match. Whether you're running a 1/10 scale RC buggy, a 1/8 scale truggy, or any ARRMA RC model with compatible suspension geometry, these caps represent genuine OEM quality replacement parts manufactured to the same standards as your original equipment.

Frequently Asked Questions
- Why should I replace my RC shock caps with aluminium versions? — Aluminium shock caps offer multiple advantages over plastic: they're significantly lighter, which improves your RC car's acceleration and handling; they're more durable and resistant to damage during heavy bashing; and they provide a more professional appearance. If your existing caps are cracked, worn or you simply want to optimise your RC vehicle's performance, upgrading to quality aluminium caps is a smart investment.
- Will these shock caps fit my ARRMA RC model? — These are genuine ARRMA suspension spares manufactured to OEM specifications. They're designed as replacement parts for ARRMA RC vehicles with compatible suspension systems. If you're unsure whether they fit your specific model, check your vehicle's documentation or contact our team at RC Model Shop—we have expert knowledge of the full ARRMA range and can confirm compatibility before you purchase.
- How often will I need to replace shock caps? — With proper care, quality aluminium shock caps like these last considerably longer than plastic alternatives. However, if you bash hard or compete regularly, you may occasionally need spares. It's always sensible to have a pair on hand so you're never sidelined by a damaged cap. The precision threads mean they'll perform perfectly every time you service your shocks.
- What's the difference between anodised aluminium and painted alternatives? — Anodising creates a protective oxide layer that becomes part of the metal itself, providing superior corrosion resistance, scratch resistance and durability. Painted finishes can chip and peel, exposing bare metal underneath. Anodised parts maintain their protective qualities and appearance through heavy use, making them ideal for serious RC enthusiasts in the UK who demand reliability.
- Can I service my shocks easily with these caps? — Yes—that's one of their key advantages. The precision manufactured internal threads mean you can remove and install these caps quickly and smoothly when you need to service your shock oil or rebuild your suspension. There's no stripping of threads or installation difficulties that can occur with lower-quality caps.
