lockin2_photo2_caseID102Warner Gear’s 4WD locking hub takes advantage of ZA-8’s net shape castability, creep resistance and excellent finishing characteristics to provide a highly functional and aesthetic cover. ZA-8 alloy was chosen because it handles temperatures close to 200 degrees F, a condition not uncommon during system operation. And its creep resistance makes ZA-8 important in the maintenance of a proper leak-proof seal.
