• Grease fitting included for serviceability
• Dust boot included with chloroprene rubber material
• Castle nut and cotter pin included
• Standard replacement, non-adjustable design
• Front lower position

Detailed Description

Delphi TC6375 is engineered using OE-focused dimensional and material analysis to help match factory fit and function. Delphi subjects its steering and suspension components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and 720 hours of salt spray, to evaluate durability in harsh operating environments. This part number is used on front lower suspension locations for 2003-2010 Dodge Ram 2500 with 8 Lug Wheels, 2003-2010 Dodge Ram 3500 with 8 Lug Wheels, 2006-2008 Dodge Ram 1500 with 8 Lug Wheels, 2011-2013 Ram 2500, 2012 Ram 1500, and 2011-2012 Ram 3500. Delphi TC6375 also cross-references MOOG Chassis Products K7465 for the same application.

What It Helps Address

• Front-end looseness from worn ball joint sockets
• Clunking or popping noises from the lower suspension
• Uneven tire wear caused by excess suspension play
• Steering wander or imprecise road feel
• Inspection failure tied to worn front lower suspension joints

Installation Notes and Tips

Fits 2003-2010 Dodge Ram 2500, front lower, with 8 Lug Wheels; 2003-2010 Dodge Ram 3500, front lower, with 8 Lug Wheels; 2006-2008 Dodge Ram 1500, front lower, with 8 Lug Wheels; 2011-2013 Ram 2500, front lower; 2012 Ram 1500, front lower; and 2011-2012 Ram 3500, front lower. Verify the front lower position and wheel configuration before installation. Press-in fitment requires proper suspension service tools and a correct alignment check after replacement.
