Available now at RC Model Shop, the RPM Front A-arms offer excellent value for money and deliver results that rival far more expensive solutions. With over 5 grams of weight savings per A-arm compared to stock, plus an additional shock mount hole for fine-tuned suspension geometry, these components give you the professional-grade setup you've been searching for without the professional-grade price tag. If you want your Typhon to perform at its absolute best, this upgrade is non-negotiable.

Key Features

• Exclusive Second Shock Mount Hole — RPM has added a second shock mount position to the outside of the original stock shock mount, giving you unprecedented adjustability over your front suspension geometry. This outer shock mount position lowers your ride height, which increases stability across all surface types and enables faster corner speeds by improving weight transfer during turns. The ability to select between two mounting positions means you can fine-tune your setup for different track conditions, driver preferences and racing scenarios without needing to purchase additional components.
• Lightweight Construction — Each A-arm weighs more than 5 grams less than the stock ARRMA equivalent, which might sound modest until you consider that this weight saving is achieved on components you have four of (front left, front right, rear left, rear right). The cumulative weight reduction improves acceleration, braking response and overall vehicle dynamics, whilst the lighter unsprung weight also enhances suspension compliance and tracking precision. RPM achieves this weight reduction without compromising strength, thanks to intelligent design and premium materials.
• Engineering-Grade Nylon Construction — Moulded from RPM's trademark blend of indestructible, engineering-grade nylons, these A-arms deliver unparalleled toughness and durability. The material selection is critical; RPM's proprietary nylon formulation resists impact damage, flexing and cracking far better than standard plastics, meaning your A-arms will survive the inevitable crashes and hard landings that come with serious RC car UK usage. This durability translates into fewer broken parts, less downtime and ultimately lower total cost of ownership.
• Redesigned Shape with Stock Geometry Retention — RPM's engineers have completely redesigned the A-arm profile to improve survivability during crashes whilst retaining the original stock suspension geometry. This means you get better crash resistance and a shape that's more forgiving in high-impact scenarios, yet your truck's handling characteristics remain predictable and familiar. The geometry-first approach ensures compatibility with your existing setup whilst delivering tangible improvements in real-world durability.
• Enhanced Trackability and Handling — The combination of the additional shock mount hole and improved A-arm shape produces noticeably better trackability throughout acceleration, cornering and braking. You'll experience improved front-end response, more consistent grip and reduced understeer, all of which translate into faster lap times and more predictable handling in competitive or recreational driving scenarios. The suspension feels more planted and responsive compared to stock A-arms.

Technical Performance

These front A-arms are engineered with meticulous attention to suspension geometry and material science. Constructed from RPM's proven engineering-grade nylon compound, they deliver a substantial weight reduction of more than 5 grams per A-arm compared to stock ARRMA components, contributing meaningfully to your Typhon 4x4 3S BLX's overall performance envelope. The critical innovation is the addition of a second shock mount position located on the outside of the stock mounting point, enabling suspension ride height adjustment without requiring different A-arms or complicated modifications. By moving the shock mount outward and downward, you lower the vehicle's centre of gravity, which increases stability during cornering and high-speed runs whilst enabling faster sustained corner speeds on both on-road and off-road surfaces. The engineering maintains full compatibility with your stock 3S LiPo battery setup and the vehicle's original suspension geometry, meaning installation is straightforward and your truck's handling remains balanced and predictable. The material science behind the engineering-grade nylon ensures these components withstand repeated impacts and crashes far better than standard plastic parts, reducing maintenance intervals and part replacement frequency. Whether you're racing competitively or bashing for fun, the combination of adjustability, weight savings and durability makes these A-arms a foundational upgrade for any serious Typhon 4x4 3S BLX user.

Frequently Asked Questions

• Which ARRMA vehicles do the RPM Front A-arms fit? — These RPM Front A-arms are designed specifically for the ARRMA Typhon 4×4 3S BLX model (part number AR102696). They directly replace the stock ARRMA front A-arms (part number AR330543). If you own a different ARRMA model such as the Big Rock, Senton or Granite, you should verify compatibility with the manufacturer, as different platforms use different suspension geometries and mounting points.
• How much weight will I save by upgrading to RPM Front A-arms? — Each RPM front A-arm weighs more than 5 grams less than its stock ARRMA equivalent. Since the front suspension uses two A-arms (left and right), you'll save more than 10 grams on the front end alone. This weight reduction improves acceleration, handling response and overall vehicle agility, particularly noticeable during cornering and directional changes.
• What is the second shock mount hole for and why does it matter? — The additional shock mount position allows you to lower your vehicle's ride height by repositioning where the shock absorber connects to the A-arm. A lower ride height increases your truck's stability during high-speed cornering, reduces body roll and enables faster sustained corner speeds. It also improves weight transfer during acceleration and braking. You can experiment with both mounting positions to find the setup that works best for your driving style and track conditions.
• Are these A-arms durable enough for serious bashing and racing? — Absolutely. RPM A-arms are moulded from engineering-grade nylon specifically formulated for impact resistance and durability. The material resists flexing, cracking and breaking far better than standard plastic parts, meaning they'll survive the crashes and hard landings common in RC car UK usage. The redesigned shape further improves crash survivability whilst maintaining the geometry needed for predictable handling.
• Do I need any other parts to install the RPM Front A-arms? — No, the RPM Front A-arms are a direct drop-in replacement for your stock ARRMA Typhon 4x4 3S BLX front A-arms. You'll need standard R/C tools (screwdrivers) for installation, but no additional suspension components or modifications are required. Your existing shocks, pivot balls and hardware will work perfectly with these new A-arms.
• Will upgrading to RPM A-arms change my truck's handling? — The upgrade will actually improve your truck's handling. The new A-arm design is engineered to maintain your stock Typhon's original suspension geometry, so the truck will still feel familiar, but with enhanced trackability and responsiveness. The additional shock mount hole gives you the option to lower ride height for even better stability if you choose to use that feature, but your baseline handling will feel more planted and consistent.
• Are these A-arms compatible with my 3S LiPo battery setup? — Yes, the RPM Front A-arms are engineered specifically for the ARRMA Typhon 4x4 3S BLX and work perfectly with standard 3S LiPo batteries. No changes to your power system or battery setup are required; simply install the A-arms and you're ready to drive.
