Overview
The Traxxas Suspension links, Rear lower, Blue (2 pcs) are precision-engineered replacement components designed specifically for the TRX-4 Long Arm Lift Kit (#8140X). These rear lower suspension links represent essential upgrade parts for RC enthusiasts in the UK who demand maximum durability and performance from their trail-crawling machines. Whether you're a seasoned RC car UK competitor or an ambitious weekend basher, these suspension links are engineered to handle the extreme stresses of off-road terrain whilst maintaining the precise geometry your TRX-4 requires for optimal handling and control.
Built from powder-coated steel with a striking blue finish, these suspension components combine rugged durability with aesthetic appeal. The hollow ball joints ensure smooth articulation and reduced weight compared to solid alternatives, making them ideal for both rock crawling and technical trail work. As part of the long arm lift kit system, these rear lower links work in harmony with your suspension geometry to provide improved ground clearance and climbing ability on challenging terrain. If you're looking to upgrade your ready to run RC or enhance an existing TRX-4 build, these links are manufactured to Traxxas' exacting standards for reliability and performance.
RC Model Shop stocks genuine Traxxas suspension components, and these rear lower links are no exception. When you choose to upgrade your TRX-4's suspension system with these proven components, you're investing in parts that have been tested extensively in real-world trail conditions. The blue colour variant offers excellent visual contrast on your vehicle, making it easy to inspect for wear and damage during maintenance. These suspension links are essential for anyone running the TRX-4 Long Arm Lift Kit and wanting to maintain the integrity of their suspension geometry whilst enjoying the benefits of increased clearance and approach angles.
Key Features
- Powder-coated Steel Construction — The suspension links are manufactured from steel and then powder-coated to provide superior corrosion resistance and durability. This protective coating ensures these components will withstand repeated exposure to water, mud, and harsh trail conditions without deteriorating or rusting.
- Hollow Ball Joints — Assembled with hollow ball joints rather than solid connections, these links offer superior articulation and reduced unsprung weight. The hollow ball design allows for smoother movement through the suspension travel whilst maintaining the structural integrity needed for extreme off-road use.
- Blue Colour Finish — The striking blue powder-coat finish not only looks fantastic on your TRX-4 but also provides excellent visibility for maintenance and inspection. The colour makes it easy to spot damage or wear at a glance and allows for colour-coordinated suspension builds.
- Specifically Designed for TRX-4 Long Arm Lift Kit — These rear lower suspension links are engineered exclusively for use with the #8140X TRX-4 Long Arm Lift Kit, ensuring perfect fitment and geometry. Using the correct links maintains suspension geometry and ensures optimal performance of your lifting system.
- Pair Configuration — Supplied as a set of two links (one for each rear corner), these components are ready to install as a matched pair. The dual configuration ensures balanced suspension performance across both sides of your vehicle.
- 5x115mm Dimension Specification — The 5x115mm dimension indicates the precise length and mounting configuration of these links. This specification ensures compatibility with the long arm lift kit and maintains proper suspension geometry for optimal trail performance and climbing ability.
Technical Performance
The Traxxas Suspension links, Rear lower, represent a critical component in maintaining the integrity of your TRX-4's suspension system when upgrading to the Long Arm Lift Kit. The 5x115mm length has been precisely calculated to work in perfect harmony with the extended suspension geometry provided by the lift kit. Powder-coated steel provides an ideal balance between weight, durability, and cost-effectiveness for trail use, and the hollow ball joints reduce unsprung mass whilst allowing the full articulation required for extreme rock crawling. When combined with the #8140X TRX-4 Long Arm Lift Kit, these rear lower links help distribute suspension loads efficiently across the chassis, reducing stress concentrations at mounting points and extending the service life of your entire suspension system. The two-piece configuration allows your suspension to maintain proper Ackermann steering geometry and ensures that both rear corners of your vehicle track identically through technical terrain. These links are essential for maintaining the suspension geometry benefits that the long arm lift kit provides, including increased ground clearance, improved approach and departure angles, and enhanced obstacle-climbing ability. Whether you're running your TRX-4 on rocky mountains, sandy deserts, or muddy trail courses, these suspension links deliver the durability and precise geometry control needed for consistent performance in challenging conditions.

Frequently Asked Questions
- Are these suspension links compatible with my TRX-4 without the Long Arm Lift Kit? — These suspension links are specifically engineered for use with the #8140X TRX-4 Long Arm Lift Kit. Whilst the links may physically fit on a standard TRX-4, they will alter your suspension geometry and may not provide the correct ride height and handling characteristics. For best results and proper vehicle geometry, use these links only in conjunction with the Long Arm Lift Kit for which they were designed.
- What is the purpose of hollow ball joints compared to solid connections? — Hollow ball joints reduce unsprung weight whilst maintaining full articulation and load-bearing capacity. This means your suspension can move more freely and respond more quickly to terrain changes, which translates to better traction and more predictable handling on technical trails. The lighter construction also reduces stress on your drivetrain components.
- Will the blue powder coating fade or chip during use? — Traxxas powder coating is formulated to withstand the rigours of off-road RC use. Whilst any finish may show wear over time with heavy use, quality powder coating provides excellent durability compared to paint or raw steel. If you do notice chips or wear, you can touch up the suspension links with compatible paint to maintain corrosion resistance.
- How do I know if my suspension links need replacement? — Inspect your suspension links regularly for bent or cracked steel, loose ball joints, or excessive play when flexing the suspension by hand. If you notice your vehicle pulling to one side, have increased body roll, or experience reduced climbing ability, damaged suspension links could be the cause. Traxxas recommends inspecting links after every few hours of heavy trail use.
- Can I use these links with aftermarket suspension components from other manufacturers? — Whilst some aftermarket components may be compatible, Traxxas suspension links are engineered to work specifically with genuine Traxxas Long Arm Lift Kit components. Mixing brands can result in geometry misalignment and unpredictable handling. For optimal performance and reliability, use genuine Traxxas components throughout your suspension system.
- What tools do I need to install these suspension links? — Traxxas recommends having a metric hex driver set, which includes the tools needed to work on all Traxxas models. The 8712 7-Piece Metric Hex and Nut Driver Essentials Set is ideal for this task and includes all necessary bits for suspension work. For added torque during installation, the optional 8720 large handle is available to make tightening fasteners easier.
