RPM Rear A-Arms Blue for Associated MT8 RC Car Suspension Upgrade RPM70195

Overview

The RPM Rear A-Arms in Blue for Associated MT8 represent a significant upgrade over the stock suspension components found on your RC car. Designed specifically for the Associated Rival MT8, these reinforced rear A-arms deliver exceptional durability and reliability for UK RC enthusiasts who demand the best performance from their RC vehicles. Whether you're a serious competitor, a weekend basher, or simply looking to enhance your RC car UK setup, these upgraded A-arms provide the toughness and strength needed to handle demanding driving conditions and extended track sessions.

RPM has engineered these rear A-arms using advanced reinforcement techniques that increase material thickness and structural support throughout the entire component. The result is a suspension upgrade that resists breakage, absorbs impacts more effectively, and maintains consistent performance even under extreme stress. If you've experienced broken A-arms on your Associated MT8, or you're building a rock-solid basher that can take punishment, these RPM rear A-arms are an essential upgrade that will transform your RC off-road experience.

Available in an eye-catching blue colour, these A-arms aren't just stronger—they look fantastic too. RPM's commitment to engineering-grade nylon construction means you're getting components that can withstand the rigours of serious RC car use, whether you're racing competitively or enjoying casual weekend sessions in the UK.

Key Features

• 7% Increased Material at Inner Hinge Pins — RPM engineers reinforced the critical inner hinge pin area by increasing material thickness, which directly strengthens the attachment points where the A-arm connects to the chassis and ensures this high-stress area resists cracking and failure during aggressive driving.
• 40% Wider Inner Hinge Pin Support — Not only is the material thicker, but the width of that reinforced diameter has been increased by nearly 40%, creating a more robust foundation that distributes forces more effectively across a larger surface area.
• 28% Increased Material at Outer Hinge Pins — The outer hinge pins, which are equally critical to suspension geometry, have been strengthened with an additional 28% more material, significantly improving durability where the A-arm connects to the steering linkage and suspension.
• 9% Wider Outer Hinge Pin Section — Combined with the material increase, the outer hinge pin area is also 9% wider, providing exceptional structural integrity at this stress point.
• Full 12.7mm Thickness Over Entire Length — Unlike stock A-arms that taper down by nearly 30% at the outer hinge pins, RPM A-arms maintain a full 1/2 inch (12.7mm) thickness over nearly their entire length, delivering consistent strength throughout the component rather than weak points that are prone to breakage.
• Minimal 11.43mm Taper at Inner Hinge Pins — The only taper occurs at the inner hinge pins, and only slightly to 0.45 inch (11.43mm), which matches the maximum allowable size of the inner hinge pin bosses while maintaining exceptional structural support.
• Four Massive Support Beams — Where stock A-arms use just two support beams, RPM A-arms feature four substantially thicker support beams that provide comprehensive reinforcement throughout the component, making them the toughest alternative to stock available.
• Engineering-Grade Nylon Construction — Manufactured from nearly indestructible engineering-grade nylon, these A-arms offer superior impact resistance, durability, and reliability compared to standard plastic components found on many RC cars.
• Blue Colour Option — Available in a striking blue finish that complements modern RC car aesthetics while the nylon material resists fading and UV damage during outdoor use.
• Direct Stock Replacement — These rear A-arms directly replace the stock Associated A-arms (part number AS25911), making installation straightforward with no modification required to your Associated MT8.
• Sold in Pairs — Each purchase includes both left and right rear A-arms, so you receive a complete rear suspension upgrade ready for installation on your vehicle.

Technical Performance

The engineering excellence evident in these RPM rear A-arms stems from comprehensive analysis of how stock A-arms fail under racing and bashing stress. RPM's design philosophy addresses every weak point: the inner hinge pins are reinforced with 7% additional material and 40% wider support, whilst the outer hinge pins receive 28% more material and 9% wider bracing. The true innovation lies in the support beam design—stock A-arms taper down by nearly 30% at the outer end, creating inherent weak points exactly where forces are concentrated during hard cornering and impact events. RPM's solution is elegantly simple but devastatingly effective: maintain the full 12.7mm thickness across nearly the entire length of the A-arm, with only a slight taper (to 11.43mm) at the inner hinge pins to respect the maximum allowable boss size. To compensate for this minimal taper, RPM engineers doubled the number of support beams from two to four, each substantially beefier than stock equivalents. The result is a component that distributes stress loads more evenly, resists bending and cracking, and maintains suspension geometry consistency even after repeated high-impact impacts. The material composition—engineering-grade nylon—provides superior abrasion resistance, impact absorption, and longevity compared to standard nylon used in stock components. For RC car UK enthusiasts and serious bashers, these A-arms represent a quantum leap in suspension reliability and performance.

Frequently Asked Questions

• Will these RPM A-arms fit my Associated MT8 RC car? — Yes, these RPM rear A-arms are designed specifically as a direct replacement for the stock Associated A-arms (part number AS25911) fitted to the Associated Rival MT8, requiring no modification for installation.
• How much stronger are RPM A-arms compared to stock? — RPM A-arms feature significantly reinforced construction: 7% more material at inner hinge pins with 40% wider support, 28% more material at outer hinge pins with 9% wider bracing, and four massive support beams instead of two. Most importantly, RPM maintains full 12.7mm thickness across nearly the entire length whilst stock arms taper down by 30%, losing crucial strength exactly where it's needed most.
• Are these suitable for beginners? — These A-arms are not beginner-specific components; they're performance upgrade parts designed to improve durability on existing vehicles. If you already own an Associated MT8 and want to improve reliability and reduce breakage, these are an excellent investment regardless of experience level.
• What colour options are available? — RPM A-arms are moulded in both black and blue finishes from their engineering-grade nylon blend; this listing is for the blue colour option.
• How do I install these A-arms? — These A-arms directly replace your stock Associated rear A-arms, so installation is simply a matter of unbolting the old A-arms and bolting on the new RPM components using standard RC car tools. No modification to your vehicle is required.
• What makes RPM A-arms better than other aftermarket options? — RPM's design approach is distinctive: instead of simply thickening material everywhere, they strategically reinforce exact failure points (inner and outer hinge pins) whilst maintaining full thickness across the entire support structure and doubling the number of support beams for comprehensive reinforcement.
• Are these A-arms worth upgrading to? — If you've experienced A-arm breakage on your Associated MT8, or you frequently bash in demanding conditions, these RPM A-arms are absolutely worth the investment—they're engineered to be the toughest alternative to stock available.
