Key Features
- Precision Manufactured Spline and Thread — The servo saver shaft features precision-engineered spline geometry and threading that ensures accurate fitment and consistent operation with your servo saver assembly, eliminating play and maintaining predictable steering feel across all driving conditions.
- Stainless Steel Construction — Manufactured from stainless steel material, this shaft offers significantly increased durability compared to standard alternatives and provides excellent corrosion resistance, making it ideal for use in wet conditions and ensuring long-term reliability even in harsh RC driving environments.
- Genuine ARRMA Component — This is an official ARRMA replacement part designed specifically for the steering servo saver system, guaranteeing compatibility and performance with your KRATON 8S or OUTCAST 8S RC truck without any fitment or assembly issues.
- Protective Design — The servo saver shaft plays a critical role in the servo protection system, absorbing impact loads and preventing damage to expensive servo motors and gears during collisions and hard landings, extending the lifespan of your steering servo.
Technical Performance
The servo saver shaft is engineered with precision manufacturing standards that reflect ARRMA's commitment to quality in high-performance 1/5 scale RC vehicles. Constructed from stainless steel, the component delivers superior durability and corrosion resistance compared to conventional materials, making it suitable for extended use in diverse weather conditions across the UK. The shaft features precisely manufactured spline geometry that interfaces seamlessly with your servo saver assembly and steering linkage, maintaining zero backlash and ensuring your steering inputs translate directly to predictable vehicle response. This level of precision engineering is essential when operating competitive-grade brushless RC trucks like the KRATON 8S 4X4 RTR with its 8S LiPo battery system and high-performance servo hardware. The stainless steel material specification ensures the shaft resists corrosion from moisture and dirt ingestion, critical for maintaining structural integrity during extended use in outdoor RC driving sessions. The component's robust design allows it to effectively absorb impact loads through the servo saver mechanism, protecting sensitive servo gears from damage during aggressive cornering, jumps, and collisions.
What's in the Box
Frequently Asked Questions
- What is a servo saver shaft and why do I need one? — The servo saver shaft is a critical component in the steering system of your ARRMA RC truck that connects your servo saver assembly to the steering linkage. During impacts and hard cornering, the servo saver mechanism absorbs shock loads, and the shaft transmits steering input while protecting your expensive servo motor and gears from damage. If your shaft becomes bent, cracked, or worn, replacing it restores your steering system to factory performance.
- Which ARRMA models is this servo saver shaft compatible with? — This servo saver shaft (ARA340166) is compatible with the following ARRMA 1/5 scale brushless RC trucks: KRATON 8S 4X4 RTR (ARA110002), KRATON 8S EXB 4X4 Roller (ARA5208), KRATON 8S EXB AVC 4X4 RTR (ARA5808V2T1), OUTCAST 8S AVC 4X4 RTR (ARA5810), OUTCAST 8S EXB 4X4 Roller (ARA5210), and OUTCAST 8S EXB AVC 4X4 RTR (ARA5810V2T1).
- Is the ARRMA servo saver shaft difficult to install? — Installation is relatively straightforward for anyone with basic RC maintenance experience. The shaft connects your servo saver bellcrank assembly to your steering linkage using precision spline fitment, ensuring alignment without modification. However, we recommend referring to your ARRMA vehicle manual for detailed installation instructions to ensure proper assembly and torque specifications.
- What makes stainless steel construction important for this component? — Stainless steel provides superior corrosion resistance compared to standard steel, which is essential for RC hobby applications where your truck may be exposed to moisture, mud, and salt spray during outdoor driving sessions. The increased durability means your servo saver shaft will maintain its structural integrity and smoothness of operation over many seasons of use.
- Can I use this servo saver shaft with aftermarket servo saver arms? — This shaft is designed as a replacement for the original ARRMA component. If you upgrade to aftermarket servo saver assemblies such as those from Hot Racing, compatibility depends on whether the aftermarket product maintains the same spline geometry and fitment specifications. We recommend confirming compatibility with the aftermarket manufacturer before purchase.
- How often should I replace the servo saver shaft? — The servo saver shaft is a durable component that typically requires replacement only if it becomes damaged from impact, bending, or wear. With proper maintenance and regular inspection, a stainless steel shaft should provide years of reliable service in your brushless RC truck.
