41143 | Rear Sway Bar and Endlink Bushings - 20 mm | Challenger
Prothane Sway Bar Bushings
A sway bar bushing plays a huge role in your suspension, so don't settle for rubber. Prothane Sway Bar bushings are made of polyurethane, much more durable material for suspension bushings than rubber. Polyurethane does not break down due to road grime, weather or oils the way the rubber can. Have the peace of mind knowing you have a long-lasting part on your sway bar with Prothane's sway bar bushings. Prothane's polyurethane sway bar bushings provide a secure grip on the sway bar and do not warp over time. With this snug grip, your vehicle will see a performance boost similar to installing a larger sway bar.


Faulty Rubber
A sway bar's function is to maintain the maximum amount of road contact during tires. The sway bar is held to the frame of the vehicle with a sway bar bushing. Original Equipment rubber can warp and/or crack, losing its grip on the bar. This causes your sway bar to lose its effectiveness. Just look at the old rubber sway bar bushing to the left. Imagine how good of a grip that thing could keep on a sway bar. Go with Polyurethane.
Use Prothane's Super Grease
The metal sway bar rotates inside the sway bar bushings, so be sure to use the supplied Prothane's Super Grease to lubricate the bushings during installation. Its super important that you lubricate each bushing well to prevent any squeaking. If you'd like some extra grease just in case, pick up an extra 3 pack.

- Question:
- Will the 41143 fit my stock rear sway bar on my 2014 Chrysler 300?
- Answer:
- The 41143 will fit on a 2014 Chrysler 300, but only on a 20mm diameter sway bar. You will want to measure your sway bar diameter to make sure this is the correct bushing for your specific 300.
