- Synergy Jeep JK, LJ, TJ, XJ, ZJ D30/44 Inner Axle Sleeve Kit
- Designed to increase the strength of Front D30/44 axle housings that are prone to bending when larger off road tires are installed and used off road
- Made from 2.0" x .250 1026 DOM Tubing (1.50" ID), Machined OD to fit snugly into the stock axle housing
- Inner Axle Sleeves add a 59% increase in strength over stock
- The stock axle housing must be drilled and plug welding for installation
- Axle sleeves are not compatible with vacuum operated axle disconnect housings (1984-1991 Jeep XJ)
- The 8012-09 inner axle sleeve kit contains axle sleeves with lengths long enough to cover all applications. Trimming of axle sleeves will be required to fit applications other than the JK D30 Axle Housing.
- Inner Axle Sleeves are not compatible with Jeep JK Rubicon Recon models due to thicker axle tube housings.
