The ARRMA ARA340154 Pivot Balls (2-pack) are precision-manufactured steel components sized M3×7×10.3 mm, built to withstand crash loads and deliver long-lasting durability in ARRMA steering and suspension systems.
Key features of the ARRMA ARA340154 Ball End Set
- Steel construction – strong, crash-resistant, engineered to resist deformation under impact
- 7 mm pivot ball diameter – gives smooth articulation and secure fit with mating ball cups
- M3 thread (male) – matches standard ARRMA pivot ball hardware thread sizes
- Includes 2 pivot balls – complete left/right or spare set in single pack
- 2.5 mm hex driver fit – allows fast removal and installation using common tool sizes
Over time pivot balls can wear from dirt, abrasion, or impact, leading to loose steering, sloppy response, or poor alignment in suspension arms. The ARRMA ARA340154 balls replace worn pivot hardware, keeping coupling tight, eliminating unwanted play, and ensuring precise control during handling, acceleration, and braking.
Where and when should you use these pivot balls?
These pivot balls are used in ARRMA vehicles wherever M3×7×10.3 mm pivot hardware is required—this includes steering linkages, suspension arms, and other pivot points. When stock balls begin to show wear, corrosion, or damage, using genuine replacements like ARA340154 preserves the accuracy of steering geometry and keeps handling predictable.
How precision manufacturing improves performance
Manufactured to tight tolerances, the ball diameter and thread size are engineered precisely for consistent fit. The polished steel surface reduces friction and binding in pivot assemblies, while the hex driver fit ensures removal/installation can be performed quickly without damaging parts. When up to spec, pivot balls affect ride feel, response time, and overall mechanical integrity of the vehicle’s moving parts.
Compatibility & installation tips
Ensure your ARRMA model uses M3-thread pivot hardware and that the ball cups or sockets match the 7 mm ball diameter. Use correct tightening torque to avoid thread stripping or loosening in use. Regularly clean pivot points and re-lubricate appropriately to reduce wear, prolong lifespan, and maintain smooth articulation.
For ARRMA users who demand reliability and performance from every component, the ARRMA ARA340154 pivot balls offer excellent value. **Buy ARRMA ARA340154 balls today** to restore tight steering response and durable control in your RC vehicle’s pivot points.
