Product Details
Moog K6390 is a steering idler arm for steering, gear, and related components applications on 1988-1992 Chevrolet C1500, C2500, C3500, K1500, K2500, and 1992 Blazer and Suburban models, plus 1992 GMC C1500, C2500, C3500, K1500, K2500, and Yukon. The design includes a powdered-metal gusher bearing to help grease reach bearing surfaces, which supports smoother serviceability in demanding steering systems. This part cross-references Delphi TA2133 for the same application.
What It Helps Address
- Steering looseness or excessive play at the idler arm
- Uneven steering response during lane changes or turns
- Wear in serviceable steering linkage components
- Grease retention and lubrication issues at the bearing surface
- Replacement needs on Chevrolet and GMC truck and SUV steering systems
Installation Notes and Tips
Compatible With 1988-1992 Chevrolet C1500, C2500, C3500, K1500, K2500 and 1992 Blazer/Suburban applications, plus 1988-1992 GMC C1500, C2500, C3500, K1500, K2500 and 1992 Yukon applications. Verify mounting hole diameter and overall length before installation, and inspect adjacent steering linkage parts for wear while the system is apart. The included grease fitting supports future lubrication after installation.
Quality Assurance
MOOG is known for steering and chassis components that incorporate design updates aimed at extending service life and simplifying replacement. The K6390 follows that approach with a serviceable, pre-greased design for maintenance-focused steering repair.
