Our Jeep TJ tube sleeves are designed to add strength to the thin, and bend prone front axle tubes on your Jeep Wrangler. Today two different types of tube sleeves are available press in and weld in. While the press in tube sleeves offer the convenience of not having to weld, they also sacrifice strength. The press in tubes only have one point of contact at the outer end of the axle tube that relies on an interference fit. Our weld in version offers up to 9 points of contact, that when welded become a part of the existing axle tube. These sleeves are compatible with 35 spline aftermarket axle shafts. You will receive two tube sleeves one short and one long, removal and disassembly of your axle is required, and welding is required. This product will fit TJ, XJ, and MJ Dana 30 axles and TJ Dana 44 axles.
