If you've invested in a quality RC short course truck for the UK market, maintaining it with genuine ARRMA parts is the smart choice to preserve performance and longevity.

This is an ideal upgrade or replacement for anyone serious about their RC vehicle. Whether you've damaged your original bumpers through aggressive driving, crashed during a challenging course, or simply want backup components for extended track days, this set gives you peace of mind and keeps your short course truck performing at its best.

Key Features

• Tough Composite Material Construction — The bumpers are manufactured from durable composite material that provides long-lasting protection against impacts and collisions, absorbing energy effectively during crashes and reducing damage to the chassis frame and other components underneath.
• Enhanced Impact Resistance — The engineering and material selection of this bumper set offers increased impact resistance compared to standard plastic parts, meaning your truck can handle harder crashes and more aggressive driving without suffering structural failure.
• Molded ARRMA Logos — The front and rear bumpers feature molded ARRMA branding for authentic looks and quality assurance, maintaining the professional appearance of your short course truck whilst providing a visual confirmation of genuine ARRMA manufacture.
• Complete Bumper Assembly Solution — Rather than selling individual components, this set includes all the frames and mounting hardware needed to install both front and rear bumper systems, saving you money compared to purchasing pieces separately.
• Factory-Fit Compatibility — Designed and manufactured by ARRMA to work seamlessly with their Senton short course truck models, ensuring perfect fitment, correct alignment, and optimised protection geometry without modification or adjustment required.
• Essential Replacement Parts — These are the exact bumper components supplied with new ARRMA Senton kits, meaning replacement parts maintain 100% specification accuracy and compatibility with your vehicle's original design.

Technical Performance

The ARRMA Short Course Bumper Set represents the manufacturer's approach to durable off-road protection engineering. Constructed from tough composite materials, the bumpers are designed to withstand the punishment that short course racing delivers. The front bumper absorbs impacts from aggressive braking, head-on collisions, and frontal contact during competitive track sessions, whilst the rear bumper protects the rear bodywork, shock towers, and differential during reverse impacts and side-to-side contact common in short course racing. The composite material selection balances impact absorption with lightweight properties, ensuring the bumpers protect your vehicle without adding significant weight that would compromise the Senton's acceleration and handling characteristics. The included bumper frames distribute loads evenly across the chassis structure, preventing localised damage points and maintaining the structural integrity of the entire short course truck. ARRMA's engineering team has designed these components specifically for the rigorous demands of 1/10 scale short course racing, where high speeds, tight cornering, and competitive contact are commonplace. The moulded ARRMA logos aren't merely cosmetic—they serve as quality markers indicating genuine manufacture and proper material composition, distinguishing authentic ARRMA parts from inferior alternatives in the RC market.

Frequently Asked Questions

• Which ARRMA Senton models is this bumper set compatible with? — This Short Course Bumper Set is designed to fit the full range of ARRMA Senton short course trucks, including the Senton 3S 4WD RTR Brushless models, the Senton 4WD RTR Brushed models with both battery and charger options, and the Senton Boost 2WD RTR Brushed short course truck variants. It's the perfect replacement whether you own the latest model or have an older version in your collection.
• Is this a direct replacement for damaged bumpers? — Yes, absolutely. These are the genuine factory-original bumper components supplied with new ARRMA Senton kits. If your existing bumpers have cracked, splintered, or broken during aggressive driving or crashes, this set provides exact replacements that require no modification or adjustment to install.
• What is composite material and why is it better than plastic? — Composite material is engineered from multiple material layers combined to create superior strength and impact resistance compared to standard plastic. The composites used in ARRMA parts offer better energy absorption during impacts, crack resistance, and longevity, making them ideal for the demanding nature of RC short course racing where crashes are frequent and predictable.
• Do I need any special tools to install these bumpers? — Installation requirements depend on your specific Senton model variant, but ARRMA designs their replacement parts for straightforward installation by owners. The frames and mounting points are matched to your vehicle's chassis structure, and most installations require only basic RC tools. Refer to your vehicle's manual for detailed installation instructions.
• How often should I replace my bumpers? — Bumper replacement frequency depends entirely on your driving intensity and crash frequency. Casual weekend bashers might replace bumpers annually or bi-annually, whilst competitive racers or high-impact drivers might replace them more frequently. Having a spare bumper set on hand ensures you're never sidelined during important track days or racing events.
• Are these bumpers available separately or only as a set? — This product is sold as a complete bumper set including all frames and components necessary for both front and rear installation. Individual components are not typically available separately, making this set the cost-effective solution for complete bumper replacement.
