Delphi TC1605 Front Lower Ball Joint

Delphi TC1605 is a front lower suspension ball joint built for OE-style replacement on a wide range of Chevrolet and GMC trucks, vans, and SUVs. It combines a steel body, pressed mounting design, and included dust boot to support precise steering and suspension movement in demanding service conditions.

Key Features

  • OE-focused aftermarket steering and suspension part from Delphi
  • Steel construction with gray finish
  • Pressed mounting type for front lower applications
  • Dust boot included with chloroprene rubber material
  • Grease fitting included for serviceability
  • Castle nut, cotter pin, nuts, and mounting hardware included
  • Standard replacement grade for everyday repair work
  • Threaded stud with tapered design for secure fitment

Detailed Description

The Delphi TC1605 suspension ball joint is engineered for front lower use and built around OE dimensional and material analysis to help match factory fit and function. Delphi subjects its steering components to extreme temperature cycling from below -40 degrees C to over 120 degrees C, along with 720 hours of salt spray testing, to evaluate durability in harsh environments. This part cross-references MOOG Chassis Products K6117T and Mevotech Supreme MK6117T for the same application. It is a direct-fit option for classic Chevrolet C10, Chevrolet G10, GMC G1500, and related front lower suspension service.

  • Supports more stable steering response on older Chevrolet and GMC platforms
  • Replaces damaged dust boot or corroded ball joint hardware

Installation Notes and Tips

Verify front lower position, stud thread size, and tapered stud dimensions before installation. Because this is a pressed-style ball joint, proper removal and installation tools are recommended to avoid damage to the control arm. Inspect the mating suspension components, alignment settings, and fasteners during service, and use the included cotter pin and castle nut as specified by the vehicle application.

Quality Assurance

Delphi applies OE engineering practices to its aftermarket steering portfolio and validates parts through dimensional and material analysis for fit consistency. The TC1605 is tested for temperature extremes and salt-spray exposure to help evaluate durability in real-world suspension service.
