Moog CK621356 is a suspension control arm and ball joint assembly for the front left lower position on select Chevrolet, GMC, and Hummer applications. Built with premium-grade components and included bushings and ball joint, it is designed for heavier loads and rougher road conditions where added strength and durability matter.

Key Features

  • Premium-grade suspension control arm and ball joint assembly
  • Ball joint included for a complete front left lower service part
  • Bushings included for direct replacement of worn suspension pivot points
  • Built for heavy-duty use on trucks and SUVs that see demanding road conditions

  • Part number CK621356 for accurate catalog matching

Detailed Description

Moog CK621356 is engineered for the front left lower suspension position on a wide range of GM heavy-duty trucks and SUVs, including Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, GMC Sierra 3500 HD, Chevrolet Suburban 2500, GMC Yukon XL 2500, and Hummer H2. It also covers several classic and earlier Silverado, Sierra, and Avalanche 2500/1500 HD applications. This part cross-references Delphi TC6239 and Dorman OE Solutions 521-877 for the same application.

As a suspension control arm and ball joint assembly, CK621356 helps restore proper front suspension geometry and steering response on vehicles that work under load or travel on uneven pavement. The premium construction and included bushings support a direct repair approach for worn lower control arm assemblies.

What It Helps Address

  • Clunking or looseness from worn lower control arm bushings
  • Excess play from a worn front left lower ball joint
  • Uneven tire wear caused by suspension wear
  • Imprecise steering feel on heavy-duty GM trucks and SUVs
  • Front suspension noise over bumps and rough roads

Installation Notes and Tips

Verify vehicle year, make, model, and front left lower position before ordering. Confirm fitment on the specific Silverado, Sierra, Suburban 2500, Yukon XL 2500, Avalanche 2500, or Hummer H2 application listed for CK621356. After installation, a professional alignment is recommended to help restore correct suspension angles and tire wear characteristics.

Quality Assurance

Moog High Utilization Designs are developed for heavier loads and more punishing roads, with an emphasis on added strength, durability, and confidence in demanding service. CK621356 is a premium-grade replacement part built for the front suspension needs of select GM trucks and SUVs.
