Overview
The ARRMA Silicone Bump Stop 3x6x8mm (4) Z-ARA-2642 is an essential suspension component designed for RC enthusiasts looking to maintain optimal performance and handling in their high-performance electric RC cars. These precision-engineered bump stops are factory-approved replacement parts manufactured by ARRMA, one of the world's leading RC vehicle manufacturers. Whether you're a weekend basher enjoying outdoor RC car racing in the UK or a serious competitor pushing your machine to the limit, bump stops play a critical role in controlling suspension compression and protecting your RC vehicle's chassis from bottoming out during aggressive driving and jumps.
Bump stops are rubber or silicone components that act as a secondary cushioning system within your RC car's suspension setup. When your vehicle lands from a jump, hits rough terrain, or experiences heavy cornering forces, the bump stops compress to absorb additional energy that the primary shocks cannot handle alone. This protection is absolutely crucial for maintaining the longevity of your RC model and preventing damage to internal components. The ARRMA Silicone Bump Stop offers superior performance characteristics compared to standard rubber alternatives, providing better energy absorption and more consistent performance across a wider temperature range — making these replacements ideal for UK climates and varied outdoor conditions.
For owners of ARRMA 1/8 scale street bash models like the INFRACTION 223S DSC 4X4 RTR, having quality replacement bump stops on hand is simply good practice. Over time, silicone bump stops compress, harden, or wear out through regular use, reducing their effectiveness. By keeping a set of genuine ARRMA Silicone Bump Stop replacements in your spares box, you ensure your RC car maintains its factory-tuned suspension geometry and handling characteristics, delivering consistent performance every time you take it out.
Key Features
- Silicone construction — These bump stops are manufactured from premium silicone material rather than standard rubber, which provides superior durability, better energy absorption characteristics, and improved longevity even with regular use on demanding UK terrain and weather conditions.
- Precise dimensions 3x6x8mm — The exact 3x6x8mm sizing ensures perfect fitment and compatibility with ARRMA suspension systems, maintaining the correct suspension geometry and ride height that engineers calibrated for optimal handling performance.
- Set of four pieces — You receive four bump stops in this package, providing a complete replacement set for both front and rear suspension locations on your RC model, or allowing you to replace worn components across multiple vehicles.
- Genuine ARRMA part — This is an authentic factory part manufactured by ARRMA, guaranteeing compatibility, build quality, and performance that matches the original specifications your RC car was engineered with.
- Easy installation — Bump stops are among the simplest suspension components to replace, requiring no special tools or technical expertise, making this an ideal maintenance task for RC hobbyists of all experience levels.
Technical Performance
The ARRMA Silicone Bump Stop 3x6x8mm Z-ARA-2642 represents precision engineering in suspension tuning for 1/8 scale electric RC vehicles. Silicone bump stops offer measurably superior performance compared to traditional rubber alternatives across several critical factors. The silicone material maintains consistent compression characteristics across a broader temperature range, which is particularly important for UK drivers who may use their RC cars in varying seasonal conditions — from cold winter afternoons to warm summer sessions. The 3x6x8mm profile has been precisely calculated by ARRMA engineers to provide the ideal amount of additional suspension travel before fully bottoming out, protecting your chassis and drivetrain components while maintaining responsive handling. These bump stops work in conjunction with your vehicle's main shock absorbers; when the shocks compress fully during extreme impacts or high-speed landings, the bump stops provide a secondary cushioning stage that prevents metal-to-metal contact that could cause damage. The silicone formulation also resists deterioration better than rubber, meaning these components maintain their performance characteristics through many more cycles of compression and expansion, extending the service life of this critical wear item.
What's in the Box
- Four silicone bump stops, sized 3x6x8mm
Frequently Asked Questions
- What are bump stops and why do I need them for my RC car? — Bump stops are suspension components that provide secondary cushioning when your RC vehicle's shocks compress fully during jumps, landings, or rough terrain. They protect your chassis and internal components from bottoming out and sustaining damage. Over time, these components wear out or compress permanently, reducing their effectiveness. Keeping genuine replacement bump stops like the ARRMA Z-ARA-2642 on hand ensures your RC car maintains optimal suspension performance and protection.
- Are these bump stops compatible with my ARRMA RC car? — The ARRMA Silicone Bump Stop 3x6x8mm Z-ARA-2642 is specifically designed for ARRMA 1/8 scale vehicles including the INFRACTION 223S DSC 4X4 RTR in all colour variants (Blue/Red, Teal/Pink, and Red/Black). Always verify your specific model against the compatibility list before purchasing to ensure proper fitment.
- How often should I replace my bump stops? — Bump stop replacement intervals depend on your usage intensity. Regular weekend bashers should check their bump stops every few months, whilst competitive racers or those using their RC cars frequently may need replacements more often. Signs of wear include visible compression, hardening, or loss of responsiveness in suspension feel. These silicone bump stops offer extended service life compared to rubber alternatives.
- What is the difference between silicone and rubber bump stops? — Silicone bump stops provide superior performance compared to traditional rubber alternatives. Silicone maintains consistent compression characteristics across a wider temperature range, resists permanent deformation better, absorbs energy more effectively, and lasts considerably longer through repeated compression cycles. For UK drivers facing variable weather conditions, silicone bump stops deliver more predictable and reliable suspension performance.
- Is this a genuine ARRMA part? — Yes, the Z-ARA-2642 is an authentic factory part manufactured by ARRMA. When you purchase genuine OEM parts like these silicone bump stops from authorised retailers, you receive components that match your vehicle's original specifications and engineering tolerances, ensuring optimal compatibility and performance.
