RPM Heavy Duty Rear A-arms for Losi Mini-T 2.0 Mini Buggy RC72152

Overview

If you're a Losi Mini-T 2.0 owner who's experienced the frustration of breaking stock A-arms during aggressive bashing or competitive racing, RPM Heavy Duty Rear A-arms offer the ultimate solution. These replacement rear A-arms have been specifically engineered to withstand the demands of serious RC car enthusiasts across the UK and beyond. Whether you're tackling rough terrain, pushing your mini buggy to its limits on the track, or simply want to upgrade your RC car UK setup with more durable components, these Heavy Duty Rear A-arms deliver the durability and performance that stock components simply cannot match.

RPM has earned a stellar reputation in the RC hobby for producing some of the toughest aftermarket parts available, and these rear A-arms are no exception. Built using some of the best engineering-grade nylon materials in the industry, they combine ultralight construction with unmatched durability. The development team at RPM has carefully analysed weak points in the original Losi design and systematically strengthened every critical area. The result is a set of rear A-arms that will be the last thing to fail on your Mini-T 2.0, allowing you to focus on driving rather than worrying about component failure.

What truly sets these A-arms apart is the attention to detail in their engineering. Unlike cheap alternatives or inferior copies, RPM's Heavy Duty Rear A-arms are proudly American made and backed by the company's reputation for excellence. The unique shock surround design protects the lower shock bottom, capturing the shock pivot ball and preventing the kind of direct impact damage that often occurs with stock setups. When you invest in RPM Heavy Duty components for your brushless RC buggy, you're investing in reliability, performance and the confidence to push your Mini-T 2.0 to its full potential.

Key Features

• Inner Hinge Pin Bosses – 25% Thicker Than Stock — The inner hinge pin bosses have been beefed up to roughly 25% thicker than the standard Losi second-generation stock A-arms, and dramatically thicker than the earlier first-generation design. This increased thickness means these critical connection points will resist bending and deformation far better when you're hammering through jumps and rough terrain on your RC car.
• Overall Thickness Increased by 25% — The entire A-arm structure has been thickened by approximately 25% compared to stock Losi parts, creating a more robust component that distributes impact forces across a wider area. This comprehensive strengthening approach means the A-arms maintain their integrity even during the most demanding driving sessions.
• Support Beams – 50% Thicker Construction — The support beams throughout the A-arm assembly are now roughly 50% thicker than some of the thinner supports found on stock Losi A-arms. These beams are engineered with consistent thickness throughout, providing maximum rigidity and resistance to flexing or cracking under stress.
• Enhanced Shock Pivot Protection — Unique shock surround design protects the lower shock bottom and captures the shock pivot ball, preventing it from becoming fully exposed and vulnerable to impact damage. This innovative feature means the A-arm strikes debris first, rather than the more delicate shock pivot assembly, significantly extending the lifespan of your entire suspension system.
• Engineering-Grade Nylon Construction — Built from some of the best engineering-grade nylon materials available in the RC industry, these A-arms deliver the perfect balance of lightweight construction and exceptional durability. You get reduced unsprung weight for better handling without sacrificing the toughness you need.
• Direct Losi Mini-T 2.0 Compatibility — These Heavy Duty Rear A-arms are engineered to perfectly replace the stock rear A-arms from standard Losi stock number LOS214003, ensuring perfect fitment and immediate compatibility with your Mini-T 2.0 without requiring any modifications or adaptations.
• American Made Quality — RPM products are proudly manufactured in the USA to exacting standards. This commitment to domestic manufacturing ensures consistent quality control and supports a brand dedicated to delivering the best possible RC components to hobbyists worldwide.

Technical Performance

These Heavy Duty Rear A-arms represent a significant engineering upgrade over factory Losi components. The comprehensive strengthening programme addresses every aspect of A-arm durability without compromising the lightweight construction that's essential for optimal handling in competitive and recreational driving. The front inner hinge pin bosses, which experience tremendous stress during acceleration, braking and cornering, benefit from a substantial 25% thickness increase. Combined with an overall A-arm thickness increase of approximately 25%, these dimensions translate into dramatically improved rigidity and impact resistance. The support beam design is particularly noteworthy – with thicknesses roughly 50% greater than the thinnest stock Losi supports, they provide superior strength whilst maintaining the ultralight profile essential for responsive handling. The unique shock surround protection system is a hallmark of RPM engineering, designed to protect your suspension components from the impact damage that commonly occurs when driving over rough terrain or debris. Built from premium engineering-grade nylon material, these A-arms deliver performance characteristics that exceed expectations for durability, weight and strength. For serious RC enthusiasts running a brushless Mini-T 2.0, whether for competitive mini buggy racing or hardcore bashing, these components provide the durability platform you need to focus on driving rather than repairs.

Frequently Asked Questions

• Are these rear A-arms worth upgrading to for my Losi Mini-T 2.0? — Absolutely, particularly if you've experienced breakage with stock components. The 25% thickness increase in the inner hinge pin bosses and overall A-arm structure, combined with support beams that are roughly 50% thicker than some stock alternatives, provide significantly improved durability. For bashers and racers who push their Mini-T 2.0 hard, these Heavy Duty A-arms are a worthwhile investment that will dramatically reduce component failure rates.
• How do these compare to original Losi stock A-arms? — Compared to Losi stock second-generation A-arms, RPM's Heavy Duty versions are engineered with thicker inner hinge pin bosses (approximately 25% thicker), a 25% increase in overall thickness, and support beams that are roughly 50% thicker than some of the thinner stock supports. Most significantly, the unique shock surround design on the RPM versions protects the lower shock bottom and captures the shock pivot ball, preventing the direct impact damage that occurs with fully exposed stock designs.
• Will these A-arms fit my Losi Mini-T 2.0? — Yes, these Heavy Duty Rear A-arms are designed as direct replacements for the rear A-arms from stock Losi number LOS214003, ensuring perfect fitment on your Mini-T 2.0 with no modifications required.
• Do I need both front and rear Heavy Duty A-arms? — Whilst this product covers the rear, RPM also manufactures Heavy Duty Front A-arms for the Mini-T 2.0. Many serious enthusiasts choose to upgrade both front and rear for complete suspension durability, though upgrading the rear alone will provide noticeable improvement in overall component lifespan.
• What makes RPM engineering different? — RPM is recognised across the RC hobby for meticulous engineering and the use of premium materials. These A-arms are built from some of the best engineering-grade nylon materials available in the industry, and they're proudly American made. The design philosophy focuses on addressing specific weak points in original designs rather than just creating oversized, heavy alternatives.
• Are these suitable for both competitive racing and casual bashing? — Yes, these Heavy Duty Rear A-arms excel in both applications. Whether you're running competitive mini buggy races on a track or bashing through rough terrain on weekends, the enhanced durability will significantly reduce the frequency of component failures and repairs.
