The TeraFlex high performance front axle tube seal is designed exclusively for the oversized 3.25" O.D. axle tubes found on Tera30 and Tera44 JK replacement housings. The outer triple O ring tube seal presses into the housing and provides a positive mud and water barrier. The inner double axle seal surface is designed with a cavity between the seal surfaces to form a grease filled pocket providing lubrication for the seals and provides another barrier to mud and grime. These are the same seals that were developed, proven and currently used in many NASCAR applications.
