Overview
The LOS Upper Trailing Arm Links (2) for the Losi Super Baja Rey are essential replacement suspension components designed to keep your 1/6 scale desert truck performing at its peak. Whether you're a seasoned RC enthusiast running a ready to run RC truck or a dedicated competitor pushing your Super Baja Rey to its limits, these genuine Losi parts ensure your suspension geometry remains perfect for maximum handling and stability. The Super Baja Rey represents one of the most popular brushless RC trucks in the UK market, and maintaining its suspension components with OEM parts is crucial for consistent performance on any terrain.
These upper trailing arm links are critical suspension elements that connect the rear axle assembly to the chassis, allowing the suspension to articulate while maintaining proper geometry and control. As wear items subject to regular stress during off-road use, replacement trailing arm links are a standard part of responsible RC maintenance. By choosing genuine Losi parts like the Z-LOS254049, you ensure compatibility with your Super Baja Rey and maintain the engineering tolerances that Losi designed into this award-winning platform.
Designed specifically for the Super Baja Rey platform, these trailing arm links work in conjunction with the truck's long-travel suspension system, which features coil-over oil-filled shocks and 4-link solid axle rear suspension geometry. The Super Baja Rey's extended wheelbase (20.2 inches) and optimised suspension geometry provide excellent stability across rough terrain, and keeping components like these trailing arm links in perfect condition is essential for maintaining that performance.
Key Features
- Genuine Losi OEM Component — These are authentic Losi factory parts manufactured to the exact specifications required for your Super Baja Rey, ensuring perfect fitment and reliable performance without compatibility concerns.
- Pack of Two — This pack contains two trailing arm links, which is the complete pair needed for your rear suspension assembly, making replacement straightforward and cost-effective.
- Designed for 1/6 Scale Super Baja Rey — These links are engineered specifically for the Losi Super Baja Rey platform, including the SBR 2.0 variant, ensuring they work perfectly with the truck's 4-link solid axle rear suspension system.
- Suspension Geometry Critical — Trailing arm links directly affect suspension articulation, wheel alignment, and overall handling characteristics, making them one of the most important suspension wear items on your 1/6 scale RC truck.
- Durable Construction — Built to withstand the forces generated by a powerful brushless 750kv motor and 8S capable ESC, these components are engineered for reliability during high-performance driving.
Technical Performance
The Super Baja Rey platform utilizes a sophisticated 4-link solid axle rear suspension system paired with long-travel coil-over oil-filled shocks to manage the extreme forces generated by its brushless drivetrain. The Spektrum Firma SMART 160 Amp 8S ESC and 750kv Firma 1/6th 5687 brushless motor are capable of unlocking blazing speeds from this 1/6 scale desert truck, with a substantial wheelbase of 20.2 inches and extended rear trailing arms designed to increase wheelbase length compared to earlier generations. The trailing arm links are critical components in this system, as they maintain the precise suspension geometry required for the rear 4-link axle assembly to articulate properly whilst keeping the axle centred under the chassis. With a ground clearance of 3.5 inches and a total vehicle weight of 21.6 lbs (9.8kg), the Super Baja Rey generates significant vertical forces during jumps and rough terrain navigation, making the structural integrity of suspension components like these trailing arm links absolutely essential. The 4mm 6061-T6 aluminium plate chassis construction of the Super Baja Rey distributes loads efficiently to the suspension mounts, and maintaining wear items like trailing arm links ensures this load path remains optimised. Losi's engineering includes sealed bevel gear differentials, an 8.22:1 final drive ratio, and shaft-driven 4WD drivetrain configuration, all of which work in harmony with a properly maintained suspension system.

Frequently Asked Questions
- What is the purpose of trailing arm links on an RC truck? — Trailing arm links are suspension components that connect the rear axle assembly to the chassis whilst allowing vertical articulation of the suspension. They maintain the correct suspension geometry and wheel alignment as the suspension compresses and extends, which is critical for handling, traction, and stability on uneven terrain. Worn or damaged trailing arm links can cause poor handling characteristics and reduced suspension effectiveness on your brushless RC truck.
- How do I know if my Super Baja Rey needs new trailing arm links? — Signs of worn trailing arm links include loose or mushy suspension feel, unpredictable handling behaviour, or visible cracks and damage to the components. If you've been running your ready to run RC truck hard on rough terrain, periodic inspection and replacement of these wear items is part of responsible maintenance.
- Are these parts compatible with all Super Baja Rey models? — These upper trailing arm links are designed for the Losi Super Baja Rey platform, including the SBR 2.0 variant with its extended wheelbase and longer rear trailing arms. Always verify that Z-LOS254049 is the correct part number for your specific model before ordering.
- What tools do I need to replace these trailing arm links? — You will need basic RC hand tools, typically an Allen wrench set in metric sizes. Consult your Super Baja Rey manual for the specific tool requirements and detailed installation instructions for your model.
- Why should I choose genuine Losi replacement parts? — Genuine OEM parts like these are manufactured to exact specifications by Losi, ensuring perfect fitment, correct geometry, and reliable performance. Genuine parts also maintain your RC truck's engineering integrity, which is especially important on a high-performance platform like the Super Baja Rey with its powerful brushless motor and 8S capable system.
