Traxxas Long Arm Lift Kit, TRX-4, complete (includes Red powder coated links, Red-anodised shocks) TRX8140R

Overview

The Traxxas Long Arm Lift Kit is a comprehensive suspension upgrade designed specifically for the TRX-4 1/10 scale crawler, transforming your RC truck into a terrain-conquering machine capable of tackling the most challenging off-road obstacles. Whether you're an experienced RC enthusiast looking to enhance your TRX-4's capabilities or someone new to the world of RC crawlers in the UK, this complete lift kit provides everything you need to significantly increase ground clearance and accommodation for larger 2.2-inch wheels and tyres. The kit represents a significant investment in your TRX-4's performance, combining premium aluminium components with powder-coated steel links to deliver both durability and visual impact on the trail.

Built to the exacting standards you'd expect from Traxxas, one of the most recognised and trusted names in RC vehicles worldwide, this long arm lift kit is engineered to maintain proper suspension geometry and steering characteristics even with the increased ride height. The inclusion of longer GTS red-anodised aluminium shocks means your TRX-4 will have the damping performance needed to handle rough terrain with smooth, controlled articulation. This is not merely a cosmetic upgrade; it's a functional enhancement that opens up new possibilities for your crawler, allowing you to navigate terrain that would previously have been out of reach due to ground clearance limitations.

Available ready to install as a complete package, the Traxxas Long Arm Lift Kit eliminates the guesswork of sourcing compatible components individually. If you're shopping for RC suspension upgrades in the UK, you'll appreciate that this kit has been engineered as a cohesive system where every component works in harmony. The revised servo mount is a particularly clever engineering touch, ensuring that lowering the servo maintains the correct suspension geometry and steering response, preventing the handling quirks that can sometimes accompany major suspension modifications.

Key Features

• Complete lift kit system — Unlike partial upgrades, this comprehensive package includes everything required for a full suspension transformation: longer GTS red-anodised aluminium shocks, springs, extended driveshafts, red powder-coated suspension links, and T-Lock cables. This means you're purchasing a complete, engineered solution rather than mixing components from different manufacturers.
• Red powder-coated suspension links — The powder coating provides excellent corrosion resistance and durability for outdoor use in UK weather conditions, whilst the striking red colour adds visual appeal and makes your TRX-4 stand out on the trail. Powder coating is significantly more durable than standard paint and resists chipping and fading better over time.
• Red-anodised aluminium GTS shocks — The bright red anodised finish on the four included GTS coilover shocks serves both aesthetic and protective purposes, giving your TRX-4 a stunning appearance whilst the anodised aluminium is harder and more corrosion-resistant than bare metal. These are longer versions specifically designed for the long-arm lift kit, essential for maintaining proper suspension travel and performance.
• Silky-smooth damping performance — The GTS coilover shock design delivers refined damping characteristics that tame even the roughest trails, keeping your TRX-4 stable and controlled over rocks, roots, and uneven terrain. This level of damping performance is what separates quality aftermarket shocks from basic alternatives.
• Threaded shock bodies for ride height adjustment — The aluminium shock bodies feature threading that allows you to adjust your ride height using the spring retaining collar, giving you the ability to fine-tune your TRX-4's stance and suspension characteristics to match your driving style and terrain. This adjustability is invaluable for serious crawlers.
• Accommodates larger 2.2-inch wheels and tyres — The increased ground clearance provided by the lift kit means you can safely fit bigger 2.2-inch wheels and tyres to your TRX-4, improving traction, appearance, and obstacle-clearing capability. The larger contact patch provides better grip on technical terrain.
• Revised servo mount for proper geometry — Rather than simply raising the truck, this kit includes a revised servo mount that lowers the servo position to maintain correct suspension and steering geometry. This engineering detail is crucial because it prevents the handling and steering issues that can occur when raising a vehicle without compensating for the linkage angles.
• Extended driveshafts included — The longer driveshafts ensure that the drivetrain remains properly aligned and functions smoothly with the increased suspension travel and geometry changes. Incorrect driveshaft length can cause vibration, binding, and accelerated wear on drivetrain components.
• T-Lock cables included — These specialised cables provide additional support and stability to the suspension links, particularly important when tackling extreme terrain where suspension articulation is pushed to the limit.

Technical Performance

The Traxxas Long Arm Lift Kit represents premium engineering focused on enhancing the TRX-4's crawling capability without compromising reliability or handling characteristics. The four included GTS red-anodised aluminium shocks are the centrepiece of this upgrade, providing substantially longer travel than standard TRX-4 shocks whilst maintaining smooth, progressive damping characteristics. The aluminium construction keeps shock weight minimal whilst providing excellent strength and thermal characteristics, important because shocks that dissipate heat effectively perform more consistently across extended use sessions. The threaded bodies allow adjustment of ride height through the spring retaining collar, giving you control over your TRX-4's stance and suspension preload. This is particularly valuable when exploring different terrain types, as you can adjust the setup to optimise performance on rocks, in sand, or over obstacles. The red-anodised finish isn't purely cosmetic; anodising creates a hardened surface layer that significantly resists corrosion from moisture and salt, important for UK climates where wet and muddy conditions are common. The complete package addresses the critical geometry changes required when lifting a crawler. The revised servo mount design ensures that whilst your TRX-4 sits higher for increased ground clearance, the servo remains properly positioned to maintain correct steering linkage angles and suspension geometry. This prevents the incremental steering drift and handling issues that occur when suspension modifications aren't properly engineered as a system. The powder-coated suspension links provide similar corrosion resistance and durability as the shock anodising, with the added benefit that powder coating is significantly tougher than traditional paint finishes, resisting impact damage from trail obstacles. The inclusion of extended driveshafts and T-Lock cables demonstrates Traxxas's attention to detail; these components ensure that the entire suspension system works harmoniously, with proper alignment and support throughout the increased articulation range.

Frequently Asked Questions

• Will the Traxxas Long Arm Lift Kit fit my TRX-4? — Yes, this lift kit is designed specifically for the TRX-4 platform and is compatible with multiple TRX-4 variants including the Chevrolet K10 Cheyenne High Trail Edition, Ford F-150 Ranger XLT High Trail Edition, 1972 Chevrolet K5 Blazer High Trail Edition, 1979 Chevy Blazer, Nissan Pathfinder SE-V6, 2021 Ford Bronco, Defender, and TRX-4 Sport models in various colours including red, black, blue, silver, copper, brown, orange, green and sand.
• What is the main benefit of the long arm lift kit? — The primary benefit is increased ground clearance, allowing your TRX-4 to accommodate larger 2.2-inch wheels and tyres whilst maintaining proper suspension geometry. This increases your ability to clear obstacles and navigate challenging terrain that would be impossible with standard suspension.
• Are the shocks easy to adjust? — Yes, the threaded aluminium shock bodies are designed for easy ride height adjustment using the spring retaining collar. You can adjust your suspension setup without needing specialised tools, making it straightforward to dial in the perfect height and preload for your specific driving conditions.
• What makes the GTS shocks special? — The GTS coilover shocks are engineered to deliver silky-smooth damping performance, meaning they compress and extend smoothly over rough terrain rather than harsh or jarring. This provides excellent control and stability on technical trails. The longer length is specifically designed for this lift kit, ensuring proper suspension travel and articulation.
• Why is the revised servo mount important? — When you raise your TRX-4's suspension, the angles of steering linkages change significantly. The revised servo mount lowers the servo position to compensate for these geometry changes, maintaining correct steering response and suspension characteristics. Without this engineering detail, your TRX-4 would suffer from steering issues and compromised handling.
• What's the difference between powder coating and anodising? — Both finishes provide corrosion resistance, but they work differently. Anodising creates a hardened oxide layer on aluminium, making the metal itself more durable and corrosion-resistant, which is why the shocks are anodised. Powder coating applies a polymer finish that's extremely durable and impact-resistant, making it ideal for the suspension links that might contact trail obstacles.
• Can I use my existing TRX-4 wheels with this kit? — The lift kit is designed to accommodate larger 2.2-inch wheels and tyres, so whilst standard wheels might fit, you'll miss out on the main benefit of the increased ground clearance. Most users pair this kit with upgraded 2.2-inch wheels and tyres to fully realise the performance benefits.
• Is this suitable for beginners to RC crawling? — This is an upgrade kit for existing TRX-4 owners rather than a complete ready-to-run system, so it's best suited for users who are already familiar with RC assembly and maintenance. However, if you own a TRX-4 and are serious about improving its trail capability, this is an excellent investment.
• What terrain can my TRX-4 handle with this kit? — The increased ground clearance and improved suspension articulation allow your TRX-4 to tackle significantly more challenging terrain than stock, including rocky crawls, tight technical sections, and terrain with larger obstacles. The silky-smooth damping and proper geometry ensure stable, controlled performance across diverse trail conditions.
• How does the T-Lock cable system work? — T-Lock cables provide additional support and stability to the suspension links during extreme articulation, preventing link deflection or bending under the stresses of aggressive crawling. This is particularly important on rocky, technical terrain where suspension components experience heavy loads.
