Traxxas Long Arm Lift Kit, TRX-4, complete (includes Blue powder coated links, Blue-anodised shocks) TRX8140X

Overview

The Traxxas Long Arm Lift Kit is an essential suspension upgrade for TRX-4 enthusiasts across the UK who want to take their scale crawlers to the next level. This complete lift kit transforms your TRX-4 by raising the chassis and increasing ground clearance, allowing you to fit larger 2.2-inch wheels and tyres that conquer more challenging terrain. Whether you're tackling rocky trails, deep ruts, or technical rock gardens, this suspension upgrade gives your RC crawler the extra height and capability needed to perform at its best. The kit represents a significant performance enhancement for anyone serious about maximising their TRX-4's potential on the trail.

Designed and engineered by Traxxas, the world's leading manufacturer of ready to run RC vehicles and performance upgrades, this lift kit comes as a complete system that handles the complex work for you. Rather than piecemeal upgrades, you're getting a fully integrated solution that raises your vehicle while maintaining proper suspension geometry and steering characteristics. The blue powder-coated suspension links and blue-anodised shocks give your TRX-4 a striking appearance alongside the functional performance gains. This is an ideal upgrade for RC car enthusiasts in the UK who want a proven, manufacturer-backed solution to transform their crawler.

Installing the Long Arm Lift Kit demonstrates Traxxas's engineering expertise. The kit doesn't simply lift the vehicle; it includes revised servo mounting that lowers the servo to maintain proper suspension and steering geometry. This attention to detail ensures that your TRX-4 handles as well as it looks, delivering balanced performance across all terrain types. It's a sophisticated upgrade that appeals to intermediate and advanced RC crawler pilots who understand the importance of suspension geometry in performance.

Key Features

• Increased Ground Clearance — The primary function of this lift kit is to raise your TRX-4 substantially, providing more space between the chassis and the ground to accommodate larger 2.2-inch wheels and tyres that would otherwise contact the body or chassis.
• Longer GTS Aluminium Shocks — The kit includes purpose-designed longer shock absorbers with GTS damping characteristics, which maintain responsive suspension travel across increased suspension height and work seamlessly with the extended arm geometry.
• Extended Suspension Links — New suspension links are supplied that maintain proper geometry when the vehicle is lifted, ensuring that suspension articulation remains effective and steering response stays predictable.
• Complete Driveshaft Package — Longer driveshafts are included to accommodate the increased suspension travel and geometry changes, ensuring smooth power delivery without binding or premature wear.
• T-Lock Cable System — The kit incorporates T-Lock cables that provide additional suspension support and control, helping manage the increased suspension geometry and keeping articulation consistent during extreme off-road driving.
• Revised Servo Mount — A redesigned servo mounting system lowers the steering servo to maintain proper suspension geometry and steering response, a critical design consideration that many basic lift kits overlook.
• Blue Anodised Components — The shocks feature blue anodising whilst the suspension links are finished in blue powder coating, delivering an attractive appearance that transforms your TRX-4's aesthetic whilst providing hard-wearing protective finishes.
• Suspension Springs Included — New suspension springs are part of the complete package, tuned to work with the longer shocks and raised geometry for optimal performance across varied terrain.
• Comprehensive Kit — No Additional Parts Needed — Everything required for the lift conversion is included in this package, meaning you won't need to source additional components from multiple suppliers to complete the installation.

Technical Performance

The Traxxas Long Arm Lift Kit represents a significant engineering undertaking in suspension design. The system works by extending the suspension mounting points vertically whilst incorporating longer GTS aluminium shocks that provide dampening across the increased suspension travel. The included suspension links maintain proper steering and suspension geometry throughout the vehicle's articulation range, preventing binding, excessive wear, and geometry-related handling problems that can occur with poorly designed lift kits. The longer driveshafts ensure constant-velocity power delivery without strain or noise, whilst the T-Lock cables provide supplementary support to suspension geometry management. The revised servo mount is a critical component that demonstrates Traxxas's understanding of crawler mechanics — by lowering the servo whilst raising the chassis, proper steering geometry is maintained and steering response remains linear and predictable. The aluminium shock bodies provide excellent durability whilst the anodised and powder-coated finishes resist corrosion from dirt, water, and salt exposure common in UK trail environments. This is a full suspension redesign, not a simple spacer kit, ensuring that your TRX-4 performs as well as it looks after the upgrade. The complete system is calibrated to work together, delivering balanced performance improvements across acceleration, braking, cornering, and articulation.

Frequently Asked Questions

• What size wheels and tyres will this lift kit support? — The Traxxas Long Arm Lift Kit is specifically designed to accommodate larger 2.2-inch wheels and tyres on your TRX-4, providing the necessary ground clearance to run tyres that would otherwise interfere with the chassis or body on the standard suspension.
• Will the Long Arm Lift Kit improve my TRX-4's off-road capability? — Yes, significantly. By raising the vehicle and providing more ground clearance, you can navigate obstacles more easily, avoid high-centre ground contact, and maintain traction across technical terrain. The increased suspension height also allows better articulation over rocks and ruts commonly found on UK trail courses.
• Do I need to replace my wheels and tyres to use this kit? — The kit is designed to accommodate larger 2.2-inch wheels and tyres, which are highly recommended to realise the full benefits of the increased ground clearance. However, you can install the kit with standard wheels first to assess the geometry changes before purchasing new rolling gear.
• Will the servo mount revision affect my steering performance? — No, the revised servo mount is engineered to maintain proper steering geometry. By lowering the servo position as the vehicle is raised, Traxxas ensures that steering response remains linear and predictable, preventing the steering geometry issues that can occur with simpler lift solutions.
• Is this kit suitable for beginners? — The Long Arm Lift Kit is primarily targeted at intermediate to advanced TRX-4 users who are comfortable performing suspension work and understand the importance of suspension geometry. The installation requires some mechanical knowledge and proper tools, though experienced RC enthusiasts should find the process straightforward.
• What materials are used in the lift kit? — The suspension links are aluminium with blue powder coating for durability and corrosion resistance. The shocks feature blue anodised aluminium bodies, providing excellent protection against the elements whilst maintaining a lightweight, high-performance design suitable for trail conditions throughout the UK.
• Can I install this kit myself? — Yes, with appropriate tools and mechanical knowledge. The kit replaces major suspension components including shocks, links, driveshafts, and the servo mount, so careful attention to installation instructions and suspension geometry is essential.
• Will this kit work with my existing TRX-4 chassis? — The Long Arm Lift Kit is compatible with the TRX-4 family of models, including various body styles such as the Chevrolet K10 Cheyenne, Ford F-150 Ranger XLT, Chevrolet K5 Blazer, Nissan Pathfinder, Ford Bronco, Defender, and TRX-4 Sport variants. Verify your specific TRX-4 model for compatibility.
• Does the kit include everything I need? — Yes, this is a complete kit that includes all suspension components necessary for the lift conversion: shocks, springs, links, driveshafts, T-Lock cables, and the revised servo mount. No additional suspension parts are required.
• What is the purpose of the T-Lock cables? — The T-Lock cables provide supplementary support to suspension geometry management and control, helping maintain consistent articulation during extreme off-road driving and rock crawling situations where suspension geometry can become compromised.
