Overview

MAS Chassis B6141 is a suspension ball joint built as a direct replacement for specific front lower applications. It is precision-engineered and tested for dependable service, with fitment covering a wide range of Chevrolet, GMC, Cadillac, Buick, Oldsmobile, and Pontiac models.

Key Features

  • Steel construction with a rubber dust boot for durable service protection.
  • Greaseable design for serviceable lubrication.
  • Pressed mounting type with a tapered stud and threaded attachment.
  • Castle nut, cotter pin hole, and mounting hardware included.
  • Standard suspension grade for OE-style replacement use.

Detailed Description

The MAS Chassis B6141 suspension ball joint is engineered for front lower suspension service on specific vehicles, including Chevrolet Astro and GMC Safari applications, along with selected Cadillac, Buick, Oldsmobile, and Pontiac models. The steel housing, metal bearing material, and rubber boot support consistent joint movement while helping protect the assembly from contamination. Part number B6141 is also referenced in interchange listings with MOOG K6141 and Delphi TC1637 for the same application.

This ball joint is a practical replacement choice when restoring steering and suspension geometry on worn OE components. Its greaseable construction and pressed-in design make it suitable for service work where a direct-fit suspension ball joint is required.

What It Helps Address

  • Excessive play in the front lower suspension joint.
  • Clunking or looseness from a worn ball joint.
  • Uneven tire wear related to suspension wear.
  • Steering instability caused by joint wear.
  • Loss of suspension precision in aging chassis components.

Installation Notes and Tips

Fits 1985-2005 Chevrolet Astro, front lower; 1985-2005 GMC Safari, front lower; 1992-1996 Cadillac Commercial Chassis, front lower; 1993-1996 Cadillac Fleetwood, front lower; 1986 Cadillac Fleetwood, front lower; 1995-1996 Chevrolet Caprice, front lower; 1987-1992 Cadillac Brougham, front lower; and additional listed Buick, Chevrolet, Oldsmobile, and Pontiac applications. Verify the press-fit diameter, stud thread size, and suspension configuration before installation. Part number B6141 should be matched to the vehicle's exact fitment listing before service begins.

Quality Assurance

MAS Chassis states that this ball joint is precision-engineered and rigorously tested for reliable replacement performance on the specified applications.
