Detailed Description

Delphi TC1611 is engineered as a front lower suspension ball joint for vehicles that use a bolt-on lower joint design. Delphi applies OE-focused dimensional and material analysis to help maintain proper fit and suspension geometry, while the alloy steel ball and carbon steel housing are built for demanding road conditions. The part is tested across extreme temperature ranges and salt-spray exposure to reflect the durability expectations of OE-style steering and suspension components. This part cross-references MOOG Chassis Products K6291 for the same application.

What It Helps Address

• Front-end looseness or play in the lower suspension joint
• Clunking or popping noises from the front suspension
• Uneven tire wear related to worn ball joint movement
• Steering wander caused by excess suspension joint clearance
• Restoring proper front lower joint support on Chevrolet and GMC applications
