Overview

The ARRMA Servo Saver Spring Set (ARA340168) is an essential replacement component for RC enthusiasts who operate 1/5 scale brushless speed trucks and stunt trucks. Whether you're running an ARRMA KRATON 8S or OUTCAST 8S model, this high-quality servo saver spring set ensures your steering system maintains optimal performance through intense bashing sessions and competitive driving. The servo saver mechanism is a critical part of any ready to run RC car, as it protects your steering servo from damage caused by impacts and collisions. When your original servo saver springs become worn or damaged, this genuine ARRMA replacement kit restores your vehicle's steering precision and responsiveness.

Servo savers work by allowing the steering linkage to slip slightly when the wheels hit obstacles, preventing the servo from experiencing catastrophic gear damage. This intelligent mechanical solution means you can bash harder and drive more aggressively without worrying about costly servo repairs. The Servo Saver Spring Set is precision-engineered to work seamlessly with ARRMA's 1/5 scale RC truck range, including the KRATON 8S 4X4 and OUTCAST 8S AVC models. If you're serious about maintaining your RC model to peak performance standards, having spare servo saver springs on hand is essential maintenance.

Built with the same exacting standards as ARRMA's original kit components, this spring set combines durability with consistent operation in extreme conditions. Whether you're a seasoned RC basher exploring the world of high-performance 1/5 scale machines or a dedicated competitor who demands reliability, the Servo Saver Spring Set delivers the quality and compatibility you need. RC car UK enthusiasts trust ARRMA for genuine replacement parts that fit perfectly and perform reliably, making this an intelligent investment in your vehicle's longevity.

Key Features

• High-Quality Spring Steel Construction — This servo saver spring set is manufactured from strong and durable spring steel, a material specifically chosen for its ability to absorb repeated impacts and restore to its original shape thousands of times without weakening or deforming, ensuring long-lasting performance even under the most demanding driving conditions.
• Precision Manufacturing for Extreme Conditions — Each component within the set is precision manufactured to exacting tolerances, guaranteeing consistent operation across temperature extremes, high-speed runs, and intense bashing scenarios that would test lesser quality parts, which is critical for maintaining steering accuracy and servo protection.
• Complete Replacement Kit — Rather than selling individual springs separately, this set includes everything needed for a full servo saver replacement: both inner and outer springs plus a precision-engineered steel washer, eliminating the guesswork and ensuring you have all compatible components that work together harmoniously.
• Genuine ARRMA Manufacturing — As an official ARRMA replacement part, this servo saver spring set meets the exact specifications and standards of the original kit-supplied item, guaranteeing perfect fitment and performance on compatible models without modification or adjustment required.
• Protection for Your Servo Investment — By maintaining proper servo saver spring tension, this replacement set protects your steering servo from impact damage that could otherwise require expensive repairs or complete servo replacement, making it a cost-effective preventative maintenance item.

Technical Performance

The Servo Saver Spring Set represents ARRMA's commitment to engineering-grade quality in replacement components. Constructed entirely from spring steel, the inner and outer springs are designed to work in concert, with the outer spring providing the primary load-bearing function and the inner spring offering secondary support and stability. The inclusion of a 17 x 27 x 1mm steel washer ensures proper load distribution across the servo saver assembly, preventing localised pressure points that could compromise spring performance over time. This tripartite design—inner spring, outer spring, and washer—creates a servo saver system that absorbs impacts smoothly whilst maintaining consistent steering response. The precision manufacturing tolerances mean that even after hundreds of impacts, these springs maintain their original characteristics, delivering predictable steering feel lap after lap. For drivers of 1/5 scale brushless RC trucks like the KRATON 8S 4X4 and OUTCAST 8S, both vehicles capable of extreme speeds and high-impact driving scenarios, having properly functioning servo saver springs isn't optional—it's essential to protecting expensive servo equipment and maintaining the precision steering that competitive driving demands.

Frequently Asked Questions

• What does a servo saver spring do on an RC truck? — A servo saver is a mechanical slip mechanism built into your steering linkage that protects your steering servo from damage when the front wheels hit obstacles at high speed. When impact occurs, the servo saver springs allow the steering linkage to slip momentarily before catching again, absorbing the shock load instead of transmitting it directly to your servo's gears. Without a functioning servo saver, the servo gears can strip or shatter under impact, resulting in expensive repairs or complete servo replacement. This is why servo saver maintenance is crucial for any high-performance RC truck, particularly 1/5 scale brushless models capable of extreme speeds and big impacts.
• How do I know if my servo saver springs need replacing? — If you notice your steering feels spongy or unresponsive, or if your servo saver doesn't engage as quickly as it should, your springs may be worn. Springs can lose their tension over time through repeated impacts, becoming less effective at protecting your servo. If your KRATON or OUTCAST feels different in the steering compared to when it was new, servo saver spring replacement should be your first maintenance step. Also, if you've crashed hard recently or noticed steering responsiveness declining over multiple bashing sessions, this replacement kit will restore your truck to factory performance.
• Will this servo saver spring set fit my ARRMA truck? — Yes, this is a genuine ARRMA OEM replacement part designed to fit all compatible KRATON 8S and OUTCAST 8S models listed in the product fitment section. Because it's the same part ARRMA supplied with your original kit, you can be certain of perfect fitment without modification or adjustment. If you own any of the listed 1/5 scale ARRMA brushless trucks, this servo saver spring set will be the correct replacement component.
• Why is the washer included in this kit? — The 17 x 27 x 1mm steel washer plays a critical role in the servo saver assembly by distributing load evenly across the springs. Without the washer, the spring ends could dig into the aluminium servo saver housing, creating stress points and compromising the effectiveness of the entire system. The washer ensures smooth, even pressure distribution, meaning the springs work optimally and your servo protection remains consistent across all driving scenarios.
• Can I use different springs or substitute components? — For optimal performance and servo protection, you should use the complete genuine ARRMA servo saver spring set as supplied. Using mismatched springs or incorrect washers can result in uneven load distribution, inconsistent steering feel, and potentially inadequate servo protection. Because the inner and outer springs are engineered to work together with the specific washer included, substituting components is not recommended and may compromise the protection your servo receives.
• Is this suitable for beginners? — Whilst servo saver spring replacement is a relatively straightforward maintenance task requiring basic mechanical knowledge, this product is a replacement spare part rather than a beginner-focused product. Beginners who have damaged their servo saver through crashes should consult their truck's assembly manual or contact an experienced RC enthusiast for installation guidance. The skill level required is lower than rebuilding an entire drivetrain, making it an accessible maintenance task for most RC hobbyists.
