OE-Style Engineering
Delphi applies OE-focused testing and dimensional analysis to its aftermarket steering and suspension portfolio. The TC7642 is built to match the intended fit and material profile of the original part, with testing that includes extreme temperature exposure and extended salt-spray resistance. This helps support consistent rear suspension geometry on Jeep Wrangler JK and Jeep Wrangler rear lower applications.
This part cross-references MOOG Chassis Products RK641777 for the same application.
What It Helps Address
- Rear suspension looseness or excess movement
- Worn rubber bushings in the rear lower control arm
- Clunking or knocking from the rear suspension
- Uneven rear axle location or alignment-related handling concerns
- Corrosion-related replacement needs on older Jeep Wrangler JK and Jeep Wrangler models
Installation Notes
Fits 2007-2017 Jeep Wrangler, Rear Lower. Fits 2018 Jeep Wrangler JK, Rear Lower. Verify the application tab for the exact position on your vehicle before installation. Mounting hardware is not included, and the arm is not pre-greased. Because this control arm uses rubber bushings and no ball joint, inspect adjacent suspension components during service and replace any worn hardware as needed.
Quality Assurance
Delphi subjects this control arm to OE-focused validation, including temperature extremes below -40 degrees C and above 120 degrees C, plus 720 hours of salt-spray exposure. The brand also uses dimensional and material analysis to support OE-style fitment for the aftermarket replacement market.
