Overview

The ARRMA Wheel Hex Aluminum 12mm (2) Z-AR330132 is an essential drivetrain spare part designed for RC enthusiasts who demand reliability and durability from their off-road machines. Whether you're running an ARRMA RC car UK model or you're a dedicated basher who pushes your vehicle to the limit, these precision-engineered wheel hexes are the perfect replacement components to keep your RC setup performing at its best. Cast from high-quality alloy material, these hexes are built to withstand the intense forces generated during aggressive driving and tough bashing action.

If you're serious about RC car racing or casual weekend bashing in the UK, you'll know that drivetrain components take a real beating. The wheel hex is the critical connection point between your motor and wheels, transferring all the power and torque from your drive system directly to the tyres. When these components wear out or break during a crash, having genuine ARRMA spares on hand means you can get back on the track or trail within minutes rather than waiting for replacements to arrive. These 12mm hexes are precision-manufactured to exact specifications, ensuring perfect fitment and consistent performance every single time you use them.

Designed specifically for ARRMA models that use 12mm hex connections, these cast alloy wheel hexes represent the perfect balance of strength, weight and cost-effectiveness. The manufacturing process creates a robust component that resists stripping and damage, even under the most demanding conditions. For anyone running a brushless RC truck, buggy or other ARRMA vehicle, keeping a spare set of these hexes in your toolbox is simply smart maintenance planning.

Key Features

• Cast Alloy Construction — The hexes are manufactured from cast alloy material, which provides an excellent strength-to-weight ratio whilst remaining affordable compared to fully machined components. Cast alloy construction means these parts can handle the shock loads and torque spikes that come from aggressive acceleration and hard landings without snapping or bending.
• Precision Manufactured Drive Pin Slot — Each hex features a precisely manufactured drive pin slot that ensures a perfect fit with your vehicle's driveshaft. This tight tolerancing prevents slippage and binding, allowing maximum power transfer from your motor to your wheels and ensuring consistent handling characteristics throughout your driving session.
• Custom Designed for ARRMA Vehicles — These hexes are specifically engineered to match the exact requirements of ARRMA RC cars and trucks. This custom design approach means compatibility is guaranteed and performance is optimised for ARRMA's engineering standards and design philosophy.
• 12mm Hex Size — The 12mm sizing is a standard specification across many ARRMA models, making these spares widely compatible across the ARRMA product range. The 12mm size provides the ideal balance of strength and compact packaging for modern RC vehicle designs.
• Supplied as a Pair — Each pack contains two hexes, giving you a complete set for one front or rear axle, or allowing you to keep spares for both ends of your vehicle. Having two hexes means you can perform complete axle maintenance or replacement without needing to order multiple packs.

Technical Performance

The ARRMA Wheel Hex Aluminum 12mm represents the result of dedicated engineering focused on delivering reliable drivetrain performance for demanding RC applications. The cast alloy material selection provides superior durability compared to plastic alternatives, resisting the repeated impacts and torsional stresses that come from high-powered brushless motors and aggressive driving techniques. The precision manufacturing process ensures that every hex maintains consistent dimensions, critical for avoiding play in the drivetrain which could cause vibration and handling issues. The drive pin slot is manufactured to tight tolerances, guaranteeing that it will engage cleanly with your driveshaft without any wobble or slack. These components are specifically engineered for ARRMA vehicles, meaning they integrate perfectly with the rest of your drivetrain system. Whether you're running a 2WD buggy, a 4WD monster truck, or any other ARRMA model with 12mm hexes, these spares will restore your vehicle to original performance specifications. The robust construction ensures these hexes can handle repeated use and occasional crashes without degrading, making them one of the most cost-effective ways to maintain your RC car UK setup in peak condition.

Frequently Asked Questions

• Which ARRMA models use 12mm wheel hexes? — The 12mm hex size is used across a wide range of ARRMA vehicles, including many of their popular buggy and truck models. To confirm compatibility with your specific ARRMA RC car, check your vehicle's manual or contact our expert team at RC Model Shop, and they'll confirm whether these hexes are the right fit for your setup.
• How often do I need to replace wheel hexes? — Under normal driving conditions, wheel hexes can last for many months or even years. However, if you regularly bash your RC vehicle hard, crash into obstacles, or drive at maximum power for extended periods, you may need to replace them more frequently. Having spare hexes on hand means you can replace worn components proactively rather than waiting for a failure that leaves you stranded away from home.
• Are these better than the plastic alternatives? — Yes, cast alloy hexes are significantly more durable and reliable than plastic components. Alloy resists stripping, provides better longevity under stress, and maintains tighter tolerances over time. For anyone serious about their RC car UK performance, alloy hexes are the preferred choice for serious use.
• Will these fit my ARRMA vehicle? — These 12mm hexes are designed specifically for ARRMA models that use 12mm hex connections. Confirm your vehicle's specification before ordering, as some ARRMA models use different hex sizes. Our team can help you verify compatibility if you're unsure.
• How difficult is it to replace wheel hexes? — Replacing hexes is a straightforward maintenance task that most RC enthusiasts can complete in just a few minutes with basic tools. Simply remove the wheel, pull off the old hex, and slide the new one onto the driveshaft. This is one of the most user-friendly spare parts to replace on any RC vehicle.
• Should I replace hexes in pairs or individually? — It's best practice to replace both hexes on the same axle at the same time, which is why these come as a pair. This ensures consistent handling and performance across the axle. However, you can replace individual hexes if only one is damaged.
