This Delphi stabilizer bar bushing kit is engineered for vehicles that use a 1-1/4 in. bar diameter and is listed for multiple front-to-frame and front-to-control-arm applications, plus select front and rear positions on 2017 Chevrolet Express and GMC Savana models.

What it is used for

• Clunking or squeaking from worn stabilizer bar bushings
• Excessive play at the stabilizer bar mounting points
• Loss of bar support caused by hardened or cracked bushings
• Fitment issues when replacing a worn OE-style suspension bushing

Installation notes and tips

Verify the bar diameter and mounting location before ordering, since this part is listed for multiple positions and notes vary by application. Fitment notes exclude vehicles with mounting brackets in certain applications, so confirm the application tab against your exact vehicle configuration. Delphi TD4003W should be matched to the correct year, make, model, and position before installation.
