Description
Whiteline KTA388 provides trailing arm upper arm for 09+ Ram 1500.
How It Works
A complete suspension arm renews the structural link and its specified mounting components as an assembly. It can simplify service compared with replacing individual pressed-in components, but included bushings and joints depend on the exact part number. Where adjustment is provided, the arm must be set as part of a complete alignment rather than installed at an assumed length.
Key Specifications
- Manufacturer part number: KTA388
- Component: Trailing Arm Upper Arm
Installation & Selection
Confirm axle, side, mounting geometry and any adjustment requirements before installation. Compare the assembly with the removed part and inspect adjoining mounts. Tighten fasteners using the prescribed procedure and have the alignment checked after fitting.
