Please check notes in each part listing to ensure the 4WD Actuator is correct for your 1998 CHEVROLET BLAZER with a 4.3L engine. DORMAN, AIRTEX / WELLS, STANDARD MOTOR PRODUCTS, & ACDELCO are competing brands, and each brand's 4WD Actuator may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a 4WD Actuator fits only certain 1998 CHEVROLET BLAZER models.
Clicking a "More Info" link will display a picture and/or other details about that 4WD Actuator in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a 4WD Actuator, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Drivetrain parts, other CHEVROLET BLAZER parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1998 CHEVROLET will not be lost if you switch.
