OE-Style Fit and Construction

Delphi TC7377 is engineered using dimensional and material analysis to match OE fitment expectations for the rear lower position. Delphi subjects its steering and suspension components to extreme temperature cycling and salt-spray exposure to evaluate durability, helping support consistent performance in demanding road conditions. This part cross-references MOOG Chassis Products RK643104 for the same application.

Vehicle Fitment

• Fits 2011-2012 Ram 1500, rear lower.
• Fits 2009-2010 Dodge Ram 1500, rear lower.

Common Repair Symptoms

• Rear suspension looseness or clunking over bumps
• Uneven rear tire wear caused by worn control arm bushings
• Imprecise rear axle location under load
• Excess vibration transferred into the chassis
• Corrosion-related wear on the original rear lower arm

Installation Notes

Verify rear lower position before installation and compare the original arm length, bushing orientation, and mounting-hole spacing to the replacement part. Because mounting hardware is not included, reuse or replace fasteners as needed according to service requirements. A professional alignment check is recommended after suspension work on Ram 1500 and Dodge Ram 1500 rear suspension components.

Quality Assurance

Delphi applies OE-focused testing and material validation to its aftermarket steering and suspension portfolio. TC7377 is built to support consistent fit and durability for rear lower control arm replacement on 2009-2012 Ram 1500 and Dodge Ram 1500 applications.
