OE-Style Front Stabilizer Bar Bushing Kit

Delphi TD4389W is a standard replacement suspension stabilizer bar bushing kit for front applications. It is built for vehicles that use a 32mm stabilizer bar, with fitment covering a wide range of Chevrolet, GMC, and Cadillac trucks and SUVs.

Fits 1996-2006 Chevrolet S10, front; Fits 1999-2006 Chevrolet Silverado 1500, front; Fits 2000-2006 Chevrolet Tahoe, front; Fits 2002-2006 Cadillac Escalade, front.

Key Features

  • Standard replacement bushing kit for front stabilizer bar service
  • Designed for 32mm bar applications where specified in fitment notes
  • OE-focused dimensional and material analysis for application matching
  • Tested across extreme temperature and salt-spray conditions
  • Direct fit coverage for multiple Chevrolet, GMC, and Cadillac platforms

Detailed Description

Delphi TD4389W is a front suspension stabilizer bar bushing kit engineered as a standard replacement for OE-style service. The fitment data includes Chevrolet S10, Silverado 1500, Tahoe, GMC Sierra 1500, Yukon, and Cadillac Escalade applications, with notes identifying 32mm bar size or increased-capacity chassis packages where required. Delphi TD4389W uses the brand’s OE-focused dimensional and material analysis to match the original part more closely and support proper suspension service on these platforms.

This part cross-references Dorman - OE Solutions 535-782 for the same application. Delphi TD4389W also cross-references MOOG Chassis Products K5248 for the same application.

What It Is Used For

  • Replacing worn stabilizer bar bushings that can create looseness in the front suspension
  • Addressing clunking or rattling from stabilizer bar movement
  • Restoring bar control when original bushings have hardened or deteriorated
  • Correcting fitment issues on 32mm front stabilizer bar applications

Installation Notes and Tips

Verify the stabilizer bar diameter and the fitment notes before installation. This part is listed for front applications only, and several vehicles require an increased-capacity package or a 32mm bar specification. Compare the original bushing dimensions and mounting style to the vehicle’s existing suspension hardware before service.

Quality Assurance

Delphi subjects its OE-based steering and suspension parts to temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt-spray exposure. TD4389W reflects that OE-oriented testing and material validation approach for aftermarket suspension service.
