RPM Front Upper and Lower A-Arms for ARRMA Kraton Talion Outcast Durango DEX8T RPM81482

Overview

The RPM Front Upper & Lower A-Arms for ARRMA Kraton, Talion and Outcast are premium suspension components engineered to deliver measurable improvements in handling, durability and precision for serious RC enthusiasts across the UK. Whether you're a weekend basher pushing your RC car to the limit on rough terrain, or a dedicated competitor looking to refine your suspension setup, these front A-arms represent a significant upgrade over factory-standard components. RPM has designed these arms with both strength and performance in mind, incorporating advanced engineering techniques to eliminate play, reduce weight and provide additional adjustment options that simply aren't available with stock parts.

Compatible with the ARRMA Kraton, Talion, Outcast and Durango DEX8T platforms, these front A-arms are the perfect complement to any serious RC car upgrade programme. If you're building a high-performance 1/8 scale monster truck or stadium truck setup, these arms will give you the precision and durability you need to compete and bash with confidence. The combination of slop elimination, weight reduction and enhanced adjustability makes these among the most sought-after suspension upgrades available for RC enthusiasts in the UK who demand the best from their vehicles.

RPM is synonymous with quality in the RC community, and these front A-arms continue that tradition with engineering-grade nylon construction that simply won't break under normal use conditions. When you upgrade to these arms, you're investing in reliability, precision and the kind of performance improvements that experienced RC racers and bashers appreciate immediately.

Key Features

• Slop Elimination Technology — The RPM front A-arms reduce unwanted movement at the inner mounts where the arms connect to the chassis, which directly translates to more precise steering response and consistent camber, caster and toe angle settings that remain stable throughout your driving sessions.
• Dual Shock Mount Positions — These arms feature a second shock mount hole positioned further out on the arm, allowing you to achieve a lower profile suspension setup where the shocks can lay down at a more aggressive angle, effectively lowering your vehicle's ride height and centre of gravity for improved handling dynamics.
• Weight Reduction — Weighing approximately 59.5 grams each compared to 66 grams for factory ARRMA parts, the RPM front A-arms are roughly 10% lighter than stock, which reduces unsprung mass and improves suspension responsiveness without sacrificing strength or durability.
• 30° Chamfered Edges — Both the leading and trailing edges of these A-arms feature precision 30-degree chamfered edges that provide smoother transitions when the suspension encounters obstacles too tall for the suspension travel to absorb, whilst also offering improved aerodynamic performance compared to stock square-edged designs.
• Engineering-Grade Nylon Construction — Every RPM A-arm is manufactured from a nearly indestructible blend of engineering-grade nylons specifically formulated to withstand the most demanding conditions, providing reliability you can depend on whether you're racing competitively or bashing hard in wet, muddy or rocky terrain.
• Sold as Upper and Lower Pair — Each package contains one upper and one lower A-arm, providing a complete front suspension upgrade for one side of your vehicle; two packages are required for a full front suspension replacement on your ARRMA or Durango platform.
• Direct Stock Replacement — These arms directly replace factory ARRMA components (#AR330218 and #AR330219) and factory Durango parts (#TD330709 and #TD330710), making installation straightforward for owners of compatible models.
• Optional Mudguard Compatibility — Whilst mudguards are sold separately, the rear A-arms in the RPM range feature moulded-in mounting points for optional mudguards (RPM #81412) to protect your driveline in wet and muddy conditions.

Technical Performance

The RPM Front Upper & Lower A-Arms represent a quantum leap forward in suspension precision for 1/8 scale RC vehicles in the ARRMA and Durango lineups. Built from high-performance engineering-grade nylon, these components are engineered to handle the extreme forces generated during aggressive acceleration, hard cornering and high-speed impacts that modern RC bashers and racers routinely subject their vehicles to. The material science behind RPM's nylon blend has been refined over years of real-world testing across countless RC platforms, resulting in a compound that resists cracking, breaking and permanent deformation even under repeated stress. Unlike budget aftermarket parts made from inferior plastics, RPM A-arms maintain their structural integrity through hundreds of hours of driving. The reduction in movement at the inner mounts (where the A-arm pivots on the hinge pins) delivers measurable improvements in suspension consistency, allowing you to dial in your camber, caster and toe settings with confidence that they'll remain stable throughout your driving session. The addition of the secondary shock mount position opens up new setup possibilities for tuning your suspension geometry, enabling a lower centre of gravity that improves cornering grip and overall stability. Weight savings of approximately 6.5 grams per arm may seem modest on paper, but this reduction in unsprung mass has a noticeable cumulative effect on suspension responsiveness, acceleration and handling feel, particularly when combined with other lightweight upgrades. The 30-degree chamfered edges aren't merely cosmetic; they serve a functional purpose by allowing the suspension to transition more smoothly over rough ground and obstacles, reducing harshness felt through the chassis and improving traction maintenance.

Frequently Asked Questions

• Are RPM A-arms a worthwhile upgrade from stock ARRMA components? — Yes, absolutely. Customers report significant improvements in handling precision, reduced flex and substantially improved durability compared to factory parts. The slop elimination alone makes a noticeable difference in steering response and suspension consistency, whilst the weight saving and secondary shock mount options provide tuning flexibility that serious RC enthusiasts appreciate. If you're planning to bash hard or race competitively, this upgrade delivers measurable benefits.
• Will these A-arms fit my Durango DEX8T or ARRMA Kraton, Talion and Outcast? — Yes, these RPM front A-arms are fully compatible with the ARRMA Kraton, Talion and Outcast platforms, as well as the Durango DEX8T. They directly replace factory component numbers AR330218 and AR330219 for ARRMA vehicles, and TD330709 and TD330710 for Durango vehicles, making installation straightforward for owners of these compatible models.
• Do I need to buy anything else to complete the front suspension upgrade? — Each package contains one upper and one lower A-arm for one side of your vehicle. To fully upgrade both sides of the front suspension, you'll need to purchase two packages. The arms are ready to install and use the same hinge pins and hardware as your factory suspension, so no additional components are required unless you want to add optional mudguards for protection in wet conditions.
• What's the difference between these front arms and the RPM rear A-arms? — Whilst both front and rear A-arms share RPM's philosophy of strength, reduced slop and weight savings, the front and rear arms have different geometries and attachment points specific to their suspension locations. The front arms (this product) weigh 59.5 grams each versus 66 grams for stock front arms, whilst the rear arms are slightly heavier at 48 grams compared to 53 grams for stock rear arms. Both offer the dual shock mount option for setup flexibility, and both feature the characteristic 30-degree chamfered edges for improved transitions and aerodynamics.
• Can I use these A-arms with the optional RPM mudguards? — These front A-arms do not feature moulded-in mudguard mounting points. The optional mudguards (RPM #81412) are designed for and compatible with the RPM rear A-arms in this range. However, mudguards are designed for rear suspension protection to prevent debris kicked up from the front tyres from contaminating the driveline.
• How much weight will I save by upgrading to these A-arms? — Each front A-arm weighs approximately 59.5 grams compared to 66 grams for factory parts, representing a saving of 6.5 grams per arm or 13 grams for a complete set (both upper and lower arms for one vehicle side). Whilst individual savings are modest, this weight reduction is unsprung mass, meaning it has a disproportionately beneficial effect on handling responsiveness compared to an equivalent reduction in sprung mass.
• Are these arms suitable for beginners, or only for experienced RC drivers? — These A-arms are suitable for RC enthusiasts of all experience levels. Beginners will benefit from the improved durability and reduced breakage compared to stock parts, whilst experienced bashers and racers will appreciate the precision tuning options and slop elimination. If you're new to upgrading your RC vehicle, installation is straightforward as these arms use the same hinge pins and mounting hardware as your factory suspension.
• What makes the secondary shock mount hole useful? — The additional shock mount position positioned further out on the arm allows you to mount your shocks at a lower angle relative to your chassis, effectively lowering your vehicle's ride height and centre of gravity. A lower centre of gravity improves cornering grip and stability, particularly beneficial for vehicles running at high speeds or navigating technical courses with tight turns. This tuning option is not available with stock suspension arms.
