Detailed Description
This Dorman jounce bumper is made for front lower suspension use where the original bumper has worn, cracked, or compressed. Its rubber construction helps restore the suspension stop function on vehicles such as the 1999-2006 Chevrolet Silverado 1500, 2000-2006 Chevrolet Tahoe, 2002-2006 Cadillac Escalade, and 1999-2006 GMC Sierra 1500. The bolt-on design and square-with-nut notes on listed applications support direct replacement on the confirmed fitments. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Problems This Part Helps Address
- Broken or deteriorated front lower jounce bumper
- Excessive suspension bottoming during compression
- Noise from worn suspension bump stops
- Loss of OE-style suspension travel control
- Damaged bumper material from age, road use, or impact
Installation Notes and Tips
Install at the front lower suspension position only on the listed applications. Verify the vehicle year, make, model, and the square-with-nut note before ordering or installation. Inspect the surrounding suspension components for wear, since a damaged jounce bumper often appears alongside other front-end service needs. Part number 523-053 should be matched to the confirmed vehicle application before installation.

Dorman states that this jounce bumper is precision-engineered and rigorously tested to provide a reliable replacement for the original equipment on specific vehicles.
