Overview
The Traxxas Suspension links, Rear lower (2 pcs) represent essential replacement and upgrade components for TRX-4 owners looking to enhance their RC crawler's performance and handling. These precision-engineered suspension links are specifically designed for use with the #8140 TRX-4 Long Arm Lift Kit, making them the perfect choice if you're upgrading your TRX-4 to a long-arm configuration. Whether you're a dedicated RC enthusiast in the UK looking to maintain your crawler or a serious basher seeking improved suspension geometry, these rear lower suspension links deliver the quality and reliability that Traxxas is renowned for.
For RC car UK enthusiasts, understanding suspension geometry is crucial to maximising your vehicle's performance both on the trail and in competitive environments. The TRX8145 rear lower suspension links are manufactured to exacting standards, ensuring consistent performance and durability through countless hours of off-road driving. These components are essential if you've installed the Long Arm Lift Kit or are planning to, as they work in harmony with the lifted geometry to provide optimal suspension articulation and ground clearance. Whether you bash in the countryside or tackle challenging terrain at RC events across the UK, these suspension links ensure your TRX-4 maintains peak performance.
Investing in genuine Traxxas spare parts means you're choosing proven engineering and compatibility. Rather than risking compatibility with aftermarket alternatives, these OEM suspension links guarantee perfect fitment and performance with your TRX-4 platform. The hollow ball design reduces unsprung weight whilst maintaining structural integrity, a detail that demonstrates Traxxas's attention to performance-oriented engineering.
Key Features
- Pack of Two Rear Lower Suspension Links — This set provides both rear lower suspension links needed for complete rear suspension assembly, ensuring you have matched pairs for balanced handling and predictable vehicle behaviour on varied terrain.
- Steel Construction — The steel material offers excellent durability and strength, resisting bending and flexing under the extreme forces encountered during aggressive off-road driving, rock crawling and technical terrain navigation.
- 5x115mm Dimensions — These specific measurements are engineered to work seamlessly with the TRX-4 Long Arm Lift Kit geometry, providing the correct suspension angles and articulation range for optimal performance with the lifted configuration.
- Assembled with Hollow Balls — The hollow ball joints reduce the overall mass of the suspension links without compromising strength, contributing to lower unsprung weight which improves suspension responsiveness and vehicle control.
- Long Arm Lift Kit Compatible — These links are purpose-designed for the #8140 TRX-4 Long Arm Lift Kit, guaranteeing perfect fitment and optimal suspension geometry when using that specific upgrade kit.
- Genuine Traxxas OEM Component — As original equipment manufacturer parts, these suspension links provide guaranteed compatibility, reliability and performance that matches the engineering standards of your TRX-4 chassis.
- Wear-Resistant Design — Built to withstand repeated articulation cycles, rock strikes and the general wear and tear of challenging terrain, these suspension links maintain their dimensions and performance characteristics over extended periods of use.
Technical Performance
The TRX8145 rear lower suspension links represent Traxxas's commitment to precision engineering in the RC crawler segment. Manufactured from steel, these components provide the rigidity required to maintain suspension geometry under load whilst the hollow ball design keeps unsprung mass to a minimum. This combination is critical for RC crawlers, where suspension articulation and control directly impact your ability to navigate obstacles and maintain traction on technical terrain. The 5x115mm dimensions are specifically calculated to work with the TRX-4 Long Arm Lift Kit's geometry, ensuring that when you upgrade your suspension system, the suspension links provide the correct angles for optimal tire contact, weight distribution and articulation range. The hollow ball connections allow smooth pivoting action whilst maintaining the tight tolerances necessary for consistent handling. Steel construction ensures these links withstand the punishment of aggressive driving, rock strikes and the constant flexing that occurs during extreme suspension articulation. For UK RC enthusiasts running challenging courses or competitive events, genuine Traxxas suspension components like these TRX8145 links ensure your setup remains reliable and performs predictably throughout extended driving sessions.

Frequently Asked Questions
- Are these suspension links compatible with standard TRX-4 setups or only with the Long Arm Lift Kit? — These suspension links are specifically engineered for use with the #8140 TRX-4 Long Arm Lift Kit. If you have a standard TRX-4 without the lift kit, you should use the original suspension links that came with your vehicle. These are replacement or upgrade components for owners who have installed the Long Arm Lift Kit.
- Why would I need to replace my rear lower suspension links? — Replacement becomes necessary if your existing suspension links have bent, cracked or become damaged from impacts during aggressive driving or rock crawling. Additionally, if you're upgrading to the Long Arm Lift Kit system, these links are essential components of that upgrade. Even without damage, some enthusiasts replace links as preventative maintenance or to ensure matched, fresh components throughout their suspension.
- What is the benefit of hollow ball joints compared to solid designs? — Hollow ball joints reduce the unsprung weight of your suspension system. In RC driving, lower unsprung weight improves suspension responsiveness, allowing the suspension to react more quickly to terrain changes and providing better wheel articulation and ground contact. This contributes to improved traction, better obstacle negotiation and more predictable handling characteristics.
- How long do these suspension links typically last? — With proper maintenance and normal driving, genuine Traxxas steel suspension links provide years of reliable service. The actual lifespan depends heavily on driving style, terrain difficulty and maintenance practices. Aggressive rock crawling will wear components faster than casual bashers. Regular inspections for bending or damage help identify wear before catastrophic failure occurs.
- Can I use aftermarket suspension links instead of genuine Traxxas parts? — Whilst some aftermarket options exist, using genuine Traxxas OEM parts guarantees perfect fitment and performance. The TRX8145 links are engineered specifically for the TRX-4 platform and Long Arm Lift Kit geometry. Aftermarket alternatives may have slightly different dimensions or tolerances that affect suspension geometry, handling and reliability. For maximum compatibility and performance, genuine Traxxas parts are the recommended choice.
- Are these suitable for beginners? — Suspension link replacement is a moderate-difficulty maintenance task suitable for anyone with basic mechanical experience and proper tools. If you've installed your Long Arm Lift Kit or performed other suspension work on your TRX-4, replacing these links follows similar procedures. If you're new to TRX-4 maintenance, the RC Model Shop team can provide guidance on installation techniques.
