Overview
The ARRMA Shock Cap Aluminum Black 6S (2) Z-AR330491 is an essential replacement part for RC enthusiasts in the UK who demand precision engineering and reliability in their high-performance RC vehicles. These lightweight aluminium shock caps are specifically designed for ARRMA's 6S brushless RC models, offering the perfect balance of durability and weight reduction. Whether you're running a 1/8 scale brushless RC buggy, speed truck, or stunt truck, or stepping up to a 1/7 scale all-road street bash machine, these shock caps provide a critical upgrade to your suspension system.
Crafted from high-quality black anodised aluminium, these shock caps are precision-manufactured to exacting standards that ARRMA is renowned for throughout the RC community. The set includes two caps, allowing you to replace both front or rear shock assemblies, or maintain spares for your collection of ready to run RC cars. Whether you're a weekend basher enjoying outdoor RC adventures across UK countryside, a competitive racer demanding consistent performance, or an experienced hobbyist maintaining a fleet of RC vehicles, these shock caps represent a genuine upgrade from standard plastic alternatives.
As spare parts go, shock caps might seem like small components, but they play an important role in maintaining your RC vehicle's performance and longevity. The internal threading mechanism requires precision manufacturing to ensure fast and easy servicing, and these ARRMA parts deliver exactly that. When you invest in quality RC cars, investing in quality replacement parts like these shock caps ensures your vehicles continue performing at their best, race after race, bash after bash.
Key Features
- High-quality black anodised aluminium construction — The material choice matters significantly in RC car performance; anodised aluminium is harder than standard aluminium alloy, resists corrosion better, and weighs considerably less than plastic alternatives, helping to reduce your vehicle's overall weight and improve acceleration and handling characteristics.
- Lightweight design for reduced vehicle weight — Every gram counts in RC racing and bashing; by upgrading to aluminium shock caps, you lower your centre of gravity and reduce unsprung weight on the suspension, which translates to more responsive handling, better ground contact, and improved consistency across different track conditions.
- Consistent performance benefits — The precision manufacturing ensures that both shock caps perform identically, maintaining balanced suspension geometry and predictable vehicle behaviour during hard cornering, acceleration, and braking; this consistency is particularly valuable in competitive racing where every tenth of a second matters.
- Precision manufactured internal threads — These aren't simply bored holes; the internal threading is precisely machined to exacting tolerances, ensuring that shock shafts install and remove smoothly without cross-threading, stripping, or jamming, which saves you time and frustration during regular maintenance and servicing.
- Fast and easy removal and fitting — The precision threads mean you can quickly service your shocks without struggling with stubborn or sticky components; this is particularly important when you're out at the track or in the field and need to make suspension adjustments between runs or repair shock damage after a hard crash.
- Genuine ARRMA OEM parts — As official replacement parts from ARRMA, these shock caps are engineered to the same specifications as those fitted to your new RC vehicle, ensuring perfect fitment and compatibility without the compromise of generic aftermarket alternatives.
Technical Performance
The ARRMA Shock Cap Aluminum Black 6S represents the pinnacle of precision engineering in RC suspension components. Built from black anodised aluminium rather than plastic, these caps deliver measurable performance improvements to your 6S brushless RC vehicles. The material science behind the choice is straightforward: aluminium offers superior strength-to-weight ratio compared to plastic, meaning your shocks maintain rigidity and structural integrity under the extreme stresses of high-speed bashing and racing, whilst simultaneously reducing the overall mass of your RC car. The 6S designation indicates these caps are designed for ARRMA's 6S LiPo powered vehicles, which typically include everything from 1/8 scale speed trucks and buggies to 1/7 scale all-road machines and desert trucks. The anodising process creates a protective oxide layer that resists corrosion from mud, water, and salt commonly encountered in outdoor RC environments across the UK. Precision manufacturing of the internal threads ensures minimal tolerance stack-up, meaning shock shafts engage smoothly and maintain consistent preload tension. This level of engineering precision directly impacts your vehicle's suspension geometry, which in turn affects handling balance, traction, and predictability during acceleration and deceleration. For competitive racers, this translates to more repeatable lap times; for casual bashers, it means more confidence pushing your RC vehicle to its limits without worrying about shock caps loosening or malfunctioning during hard use.

Frequently Asked Questions
- What ARRMA RC vehicles are compatible with these shock caps? — These shock caps fit a comprehensive range of ARRMA 6S brushless models, including the 1/8 scale Kraton 6S, Notorious 6S, Outcast 6S, Talion 6S, and Typhon 6S in various RTR and EXB configurations, plus the 1/7 scale Felony 6S, Infraction 6S, Limitless 6S, and Mojave 6S. They are also compatible with the larger 1/7 Limitless 120 8S AVC models when using 6S shock components. Always verify your specific model number before purchase to ensure perfect compatibility.
- Why should I upgrade to aluminium shock caps instead of sticking with plastic? — Aluminium shock caps provide several concrete advantages over plastic: they're significantly lighter, which reduces unsprung weight and improves suspension response; they're much stronger and more resistant to cracking or shattering under impact; they resist corrosion better in wet and muddy conditions; and the precision threading ensures reliable engagement without stripping. For anyone taking their RC hobby seriously, whether competitive racing or weekend bashing, aluminium caps represent a worthwhile upgrade.
- How often will I need to replace my shock caps? — With proper maintenance, these aluminium shock caps should last through countless shock servicing cycles. You might need replacements if you experience a serious crash that damages the threaded bore, or if you simply want spares on hand for a multi-vehicle setup. The anodised finish protects against corrosion, so these parts last considerably longer than plastic alternatives.
- Are these genuine ARRMA parts? — Yes, these are official ARRMA OEM parts manufactured to the exact same specifications as those included with new ARRMA RC vehicles. The part number AR330491 confirms authenticity, and the inclusion on ARRMA's official fitment list proves compatibility and legitimacy.
- What makes precision threading important in shock caps? — Imprecise threading leads to cross-threading, stripped holes, and loose shock caps that rattle during use; precision manufacturing ensures your shock shafts install smoothly and stay tight under the vibration and forces experienced during RC driving. This directly impacts suspension consistency and vehicle handling.
- Can I use these on 4S or 8S ARRMA vehicles? — These caps are specifically designed for 6S models. Whilst they might physically fit some other ARRMA vehicles, using mismatched components could compromise your suspension setup. Always use the correct parts for your specific vehicle model.
- Do these come pre-installed on new ARRMA RC vehicles? — Yes, all compatible new ARRMA 6S models come with plastic shock caps pre-installed. These aluminium caps are sold as upgrade or replacement parts for those wanting to improve their suspension or maintain spares.
