Overview
The Traxxas Rocker Arm Set, Long Travel with plastic bushings (8 pcs) TRX7156 is a premium suspension upgrade designed specifically for the 1/16 Traxxas Summit and other compatible 1/16 scale RC models. This aftermarket suspension component transforms your RC car UK experience by delivering significantly increased ground clearance and extended suspension travel. Whether you're a dedicated basher, weekend enthusiast, or someone looking to enhance your brushless RC vehicle's off-road capabilities, this rocker arm set offers exceptional value and noticeable performance improvements that make it one of the most popular suspension upgrades in the RC hobby community.
Long travel suspension geometry is crucial for serious off-road RC performance, and this genuine Traxxas rocker arm set delivers exactly that. By extending your vehicle's suspension articulation, these rockers allow your 1/16 scale Summit to absorb rough terrain, navigate obstacles with confidence, and maintain better contact with the ground across uneven surfaces. The set includes eight individual rocker arms with plastic bushings, providing a complete upgrade solution that's straightforward to install. RC enthusiasts across the UK consistently report dramatic improvements in ride quality, handling characteristics, and ground clearance after fitting these components.
This is not a complete vehicle but rather a high-quality suspension spare part that represents an affordable yet highly effective way to upgrade your existing 1/16 Traxxas Summit. When paired with appropriate suspension tuning and stiffer spring rates, the long travel rockers create a capable platform for aggressive off-road driving. At RC Model Shop, we stock genuine Traxxas parts because we know our customers demand authenticity, reliability, and the performance benefits that only genuine components can provide.
Key Features
- Long Travel Suspension Geometry — These rocker arms extend your vehicle's suspension travel significantly, allowing the shocks to compress and extend through a greater range of motion, which translates to improved articulation over obstacles and better grip on uneven terrain throughout your off-road driving sessions.
- Increased Ground Clearance — By altering the suspension geometry, these rockers raise your vehicle's ride height noticeably, giving you precious extra clearance to avoid belly scraping on rocks, roots, and other trail hazards that would otherwise limit your driving spots.
- Plastic Bushings Construction — The use of plastic bushings keeps moving friction to a minimum while reducing weight compared to heavier alternatives, and they provide smooth articulation that's ideal for recreational and competitive driving alike.
- Complete Eight-Piece Set — This package includes all eight rocker arms needed for a full suspension refresh, ensuring balanced geometry across all four corners of your 1/16 scale RC vehicle.
- Genuine Traxxas Quality — As an official Traxxas component, this rocker arm set meets the manufacturer's engineering standards, ensuring perfect fitment and reliable long-term durability with your existing Traxxas Summit components.
- Enhanced Suspension Articulation — The extended geometry allows each wheel to move independently through a greater arc, improving traction and stability when traversing rocky, rooted, or deeply rutted terrain where standard rockers would bottom out.
- Affordable Performance Upgrade — Compared to replacing your entire suspension system, this rocker arm set delivers substantial performance gains at a fraction of the cost, making it an outstanding value upgrade for enthusiasts seeking noticeable improvements.
Technical Performance
The Traxxas Rocker Arm Set TRX7156 represents thoughtful suspension engineering designed to maximise the potential of 1/16 scale RC vehicles. These rocker arms function as the critical linkage between your chassis, shocks, and wheels, and their geometry directly influences how your vehicle behaves across terrain. The long travel design extends the vertical space available for shock compression and extension, which means your suspension can work through greater distances before reaching its mechanical limits. This extended travel range is particularly valuable when driving your 1/16 scale RC vehicle across natural terrain, rocky trails, or purpose-built RC tracks where bumps, ruts, and obstacles demand responsive suspension that doesn't quickly bottom out. The plastic bushings selected for this rocker arm set provide an excellent balance between low friction and durability; they allow smooth, consistent movement whilst maintaining the precise geometric relationships that your suspension tuning depends upon. Real-world testing by experienced RC enthusiasts confirms that these rockers deliver massive differences in ride height and suspension performance. Users consistently report that the increased ground clearance makes a significant visual difference to their vehicle stance, whilst the extended articulation noticeably improves how their 1/16 Summit climbs obstacles and maintains traction through technical sections. For optimal results, Traxxas and experienced drivers recommend pairing these long travel rockers with stiffer spring rates—Summit blues or purples are commonly cited as ideal pairings—because the extended rocker geometry effectively reduces your spring rate by allowing greater suspension movement, so stiffer springs are necessary to maintain appropriate suspension control and body roll characteristics. The engineering is straightforward and proven, with thousands of satisfied users across the UK and worldwide confirming that this represents one of the best value suspension upgrades available for 1/16 scale RC vehicles.

Frequently Asked Questions
- Will the Traxxas long travel rocker arms fit my 1/16 Summit RC vehicle? — Yes, these rockers are specifically designed for the 1/16 Traxxas Summit. They are engineered to work with your existing Summit suspension components and chassis mounting points, so installation is straightforward for anyone with basic RC maintenance experience and the proper tools.
- How much ground clearance improvement will I see? — Verified users report a significant increase in ride height—enough that the visual difference is immediately apparent when you compare your vehicle before and after fitment. Several experienced RC drivers note that the improvement is substantial enough to dramatically reduce belly scraping on technical terrain.
- Do I need to upgrade my springs when I install these long travel rockers? — Experienced drivers strongly recommend upgrading to stiffer springs when fitting long travel rockers, because the extended geometry effectively softens your current spring setup. Most users report that Traxxas Summit Blues or Purples work exceptionally well with these rockers, improving body control and maintaining proper suspension ride height under load.
- What is the difference between long travel and standard rocker arms? — Long travel rockers extend the suspension geometry, allowing greater shock movement before bottoming out, which increases ground clearance and suspension articulation. Standard rockers use more limited geometry that restricts suspension travel. This Traxxas long travel set delivers noticeably more compliance and grip on rough terrain compared to factory standard rockers.
- What suspension oil should I use with these rockers? — Users frequently recommend using heavier shock oil (thicker viscosity) with long travel rockers because the extended geometry allows greater shock movement, so stiffer damping helps maintain proper suspension control. Consult the Traxxas manual for your specific Summit model for recommended oil weights.
- Are these rockers suitable for beginners? — These rocker arms are suspension components that require removal and installation of your existing rockers, which demands basic mechanical knowledge and proper tools. If you're comfortable performing straightforward RC suspension maintenance, these are absolutely suitable. However, if you've never worked on RC suspension before, consider having an experienced RC friend assist your first installation, or visit your local RC Model Shop where our team can provide guidance.
- Will these rockers work with other Traxxas 1/16 models besides the Summit? — These rockers are optimised for the 1/16 Traxxas Summit. Before fitting to other models, verify compatibility with Traxxas technical documentation or contact RC Model Shop to confirm fitment, as different 1/16 Traxxas vehicles may have different suspension mounting requirements.
