Traxxas Long Arm Lift Kit, TRX-4, complete (includes Green powder coated links, Green-anodised shocks) TRX8140-GRN

Overview

The Traxxas Long Arm Lift Kit for TRX-4 is an essential upgrade for UK RC enthusiasts looking to maximise their crawling potential and terrain-conquering capability. This complete suspension system raises your TRX-4 to accommodate larger 2.2" wheels and tyres, delivering the extra ground clearance you need to tackle the most challenging obstacles and rough terrain. Whether you're a seasoned RC crawler pilot or exploring the world of scale RC vehicles for the first time, this lift kit transforms your TRX-4's off-road performance and visual presence.

Designed and engineered by Traxxas, a brand recognised globally for innovation and quality in the RC car market, this Long Arm Lift Kit represents a significant mechanical upgrade that goes far beyond simple aesthetics. The kit includes everything required for a complete installation, meaning you can transform your TRX-4 without searching for individual components across multiple suppliers. For those looking to enhance their ready to run RC crawler or customise their existing TRX-4, this is a comprehensive solution that delivers measurable performance improvements.

The attention to detail extends to the preservation of suspension geometry and steering characteristics—a critical consideration for scale crawlers. With a revised servo mount that maintains proper suspension and steering geometry, Traxxas has ensured that increased ground clearance doesn't compromise the precise handling characteristics TRX-4 owners rely on. This makes it an ideal upgrade for both weekend bashers and dedicated scale crawling competitors across the UK.

Key Features

• Increased Ground Clearance — The Long Arm Lift Kit raises your TRX-4 to accommodate larger 2.2" wheels and tyres, providing significantly more ground clearance for traversing rocks, obstacles and challenging terrain that would otherwise catch the undercarriage. This directly translates to better off-road performance and the ability to tackle more extreme crawling courses.
• Longer GTS Aluminium Shocks — The kit features extended GTS aluminium shocks with springs that match the increased ride height, maintaining proper suspension travel and damping characteristics across a wider range of terrain. Aluminium construction provides durability whilst keeping weight to a minimum, essential for maintaining the TRX-4's precise handling balance.
• Extended Driveshafts — Specially engineered longer driveshafts accommodate the increased suspension geometry changes created by the lift kit, ensuring smooth power delivery to all four wheels without binding or excessive angles that could compromise drivetrain efficiency and longevity.
• Green Powder Coated Suspension Links — The kit includes green powder coated suspension links that not only provide structural strength but also deliver a cohesive, custom appearance when matched with the green-anodised shocks. Powder coating offers superior durability and weather resistance compared to standard finishes, keeping your crawler looking fresh through repeated use.
• Green-Anodised Shocks — The anodised shock bodies provide enhanced corrosion resistance and a refined aesthetic finish, whilst anodising strengthens the aluminium surface and improves resistance to the elements—critical for UK RC pilots who encounter damp conditions and varied weather.
• T-Lock Cables Included — These cables provide additional structural support and help maintain suspension geometry during extreme articulation, essential for serious scale crawling where suspension movement is extreme and precision is paramount.
• Revised Servo Mount — The included revised servo mount is engineered to lower the servo position and maintain proper suspension and steering geometry with the increased ride height. This ensures your TRX-4 retains its famed precision steering and doesn't suffer from geometry compromises that could affect drivability and scale realism.
• Complete Kit Format — This is a complete, ready-to-install kit with all major components included, eliminating the need to source multiple parts from different suppliers and ensuring compatibility across the entire suspension system.

Technical Performance

The Traxxas Long Arm Lift Kit represents an engineering solution specifically tailored for the TRX-4 platform, one of the most respected scale 4WD crawlers in the ready to run RC market. The extended GTS aluminium shocks and springs are precision-engineered to work in harmony with the longer driveshafts, suspension links and revised servo mount to create a coherent system that elevates performance without introducing handling compromises. The use of aluminium throughout the suspension components keeps unsprung weight minimal whilst providing the rigidity required for demanding off-road conditions. The green powder coated links and green-anodised shocks demonstrate Traxxas's commitment to both functional durability and visual appeal—powder coating protects against corrosion and UV degradation, particularly important for UK climate conditions where moisture exposure is frequent. The T-Lock cables add structural integrity during extreme suspension articulation, a key consideration for serious scale crawlers tackling boulder courses and technical terrain. The revised servo mount solves one of the critical engineering challenges presented by lifted suspensions: maintaining the precise steering geometry that makes the TRX-4 such a capable machine. By lowering the servo to compensate for the raised ride height, Traxxas has ensured that suspension angles remain optimised for responsive, accurate steering input throughout the vehicle's articulation range. This is the hallmark of thoughtful engineering—the lift kit doesn't simply raise your TRX-4, it comprehensively upgrades the suspension whilst preserving the mechanical principles that make the platform successful.

Frequently Asked Questions

• Will the Long Arm Lift Kit work with my existing TRX-4? — Yes, this kit is specifically designed for the Traxxas TRX-4 platform and includes all necessary components for installation. The revised servo mount ensures proper geometry is maintained with the increased ride height, making it a direct bolt-on upgrade for any standard TRX-4.
• What size tyres and wheels can I use with this lift kit? — The Long Arm Lift Kit is engineered to accommodate larger 2.2" wheels and tyres, which is the primary benefit of the system. This increased size provides additional ground clearance and improved obstacle-clearing capability whilst maintaining scale proportions with the TRX-4 platform.
• Does this kit change my TRX-4's handling characteristics? — The revised servo mount included in the kit is specifically engineered to maintain proper suspension and steering geometry despite the increased ride height. This preserves the precise steering characteristics the TRX-4 is renowned for, ensuring the kit enhances capability without compromising drivability.
• Is this suitable for beginners exploring scale RC crawlers? — Whilst the Long Arm Lift Kit is primarily an upgrade for existing TRX-4 owners rather than a beginner's first RC vehicle, it's an excellent addition for those moving beyond a standard TRX-4 and looking to expand their crawling capabilities. Installation requires mechanical ability or access to experienced RC support, so guidance from experienced UK RC retailers or community resources is recommended.
• What is the difference between this green version and other colour options? — This particular kit features green powder coated suspension links and green-anodised shocks, providing a cohesive, custom aesthetic appearance. Functionally, the suspension performance remains identical regardless of colour choice—the green finish is purely an aesthetic preference for builders wanting to create a specific visual theme for their TRX-4.
• Will the increased ground clearance affect my TRX-4's centre of gravity? — The longer GTS shocks with springs are engineered to accommodate the raised ride height whilst maintaining the suspension geometry necessary for stable, predictable handling. The revised servo mount further contributes to preserving vehicle balance and control characteristics across all terrain types.
