Delphi TD4138W Suspension Stabilizer Bar Bushing Kit - Front

Delphi Front Stabilizer Bar Bushing Kit

Delphi TD4138W is a front suspension stabilizer bar bushing kit built as a standard replacement for select GM and Isuzu applications. It uses rubber construction and OE-focused dimensional analysis to support proper fit and consistent suspension performance.

Key Features

• Rubber stabilizer bar bushings for front suspension service
• Inside diameter: 1.8
• Standard replacement grade
• Front position fitment
• OE-oriented material and dimensional analysis for application matching

Application Details

Compatible with 2002-2003 Chevrolet Trailblazer, front; 2002-2003 Chevrolet Trailblazer EXT, front; 2002-2003 GMC Envoy, front; 2002-2003 GMC Envoy XL, front; 2003 Isuzu Ascender, front to frame; and 2002-2003 Oldsmobile Bravada, front. Delphi TD4138W is also a direct-fit option for front stabilizer bar service on Chevrolet Trailblazer and GMC Envoy models with Auto Level Control (G67).

This part cross-references MOOG Chassis Products K80773 for the same application.

What It Helps Repair

• Front sway bar movement caused by worn rubber bushings
• Clunking or rattling from the front suspension
• Excessive play at the stabilizer bar mounting points
• Reduced steering response from deteriorated bushing material
• Noise and vibration transferred through the front chassis

Installation Notes

Install on the front stabilizer bar location specified for the vehicle application. Verify the inside diameter and mounting position before installation, especially on Trailblazer, Envoy, and Bravada models with Auto Level Control (G67). Inspect the stabilizer bar and surrounding hardware for wear before completing the repair.

Quality Assurance

Delphi applies OE engineering standards to its aftermarket steering and suspension parts. TD4138W is tested across extreme temperature ranges and salt-spray exposure, with dimensional and material analysis used to support OE-style compatibility and durability.
