MAS Chassis IA9424 Idler Arm Steering Linkage Component

The MAS Chassis IA9424 is a replacement idler arm designed to restore precise steering control and proper linkage geometry. As a critical component of parallelogram-style steering systems found on many trucks and SUVs, the idler arm supports and guides the center link, working in tandem with the pitman arm to translate steering wheel input into accurate wheel movement.

Key Features:

• Direct OE Replacement – Engineered to match original equipment specifications for a proper fit and function
• Precision-Forged Construction – Heavy-duty materials provide strength and resistance to fatigue under load
• Factory-Sealed Design – Helps resist contamination from dirt, moisture, and road debris
• Reduced Steering Play – Restores tight, responsive handling and eliminates looseness in the steering linkage
• Quality Engineered – MAS Chassis (now part of Dorman Products) backs its chassis components with professional-grade engineering standards

A worn or failed idler arm can cause wandering, pulling, uneven tire wear, and a loose or vague steering feel. The MAS Chassis IA9424 idler arm provides a reliable, cost-effective solution to restore steering precision and driver confidence. Professional installation is recommended.
