Please check notes in each part listing to ensure the Caliper Piston is correct for your 1979 JEEP J20 with a 5.9L 360 2BBL engine. ACDELCO, DORMAN, & RAYBESTOS are competing brands, and each brand's Caliper Piston may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Caliper Piston fits only certain 1979 JEEP J20 models.

Clicking a "More Info" link will display a picture and/or other details about that Caliper Piston in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Caliper Piston, 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 on "Find More Parts", to find more Brake/Wheel Hub parts, other JEEP J20 parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1979 JEEP will not be lost if you switch.
