Help bring back a planted, predictable front end with the QuickSteer Control Arm Bushing Kit, part number K6688. This front upper kit is designed and tested to help restore steering and handling to their original performance. Built for OE fit and function, it fits many vehicles, among them the 1999-2016 Chevrolet Silverado 1500 and the 1999-2016 GMC Sierra 1500. See the "Vehicles it fits" section for the full list of applications and engine details.
Control arm bushings cushion the pivot points where the front upper control arm mounts to the chassis. They absorb road vibration while still letting the arm move through its travel.
- High-strength rubber: Made from high-quality elastomer compounds for durability and ride performance.
- Precise engineering: Optimized for quiet operation and to resist wear, salt, road grime and oils.
- OE-style design: Engineered to match or exceed OE requirements, and built for long life and dependability.
- Rigorous testing: Put through comprehensive testing during design and development.
Your front upper bushings may need replacing if you notice clunking or knocking over bumps, vague or wandering steering, uneven tire wear, or rubber that looks cracked, torn or separated. A suspension control arm bushing kit like this one replaces the worn bushings, which helps restore vehicle handling when they are the cause. Have the suspension inspected to confirm the source before you order parts.
