TeraFlex Shafts Editorial Review

The TeraFlex 4990700 Axle Sleeve Kit for the Jeep JK Front seems to be a solid choice according to customer reviews. It was noted that the driver side fits well but the passenger side may need to be modified as it may not fit a Dana 30. The installation was easy, but it was recommended to give yourself spacing for the inner axle seals to avoid issues. Most customers recommended welding the sleeves in and noted that they slid right in and were of good quality. In terms of longevity and durability, some customers stated that they have used this with truss kits on 37s and have successfully beaten their riggs without any issues.
