JK2TJ Front Axle Swap Kit with Truss

The JK2TJ Front Axle Swap Kit with Truss gives you every bracket and the trussing needed to drop a factory JK Dana 44 front axle under an older Jeep. It relocates the factory link, sway bar, track bar, and shock mounts to the correct positions while reinforcing the housing, so you gain the stronger JK axle without weeks of measuring and fabricating.

Key Features

• 1/4" and 1/8" thick mild steel truss, precision CNC cut and bent to reinforce the axle housing itself.
• Includes all brackets for a complete swap: lower control arm mounts, shock mounts, sway bar mounts, track bar mount, and coil spring mounts. Factory JK upper control arm mounts are retained.
• Lower control arm brackets offered in both 9/16" hole and CAM-slot style so you can match your suspension.
• Brackets are jigged into the truss so they self-locate, saving hours of measuring and guesswork during install.
• Coil relief is stamped into the coil bucket for a straight coil, avoiding the bowing you get mounting a coil on a flat bucket.
• Adjustable track bar mount offers multiple mounting locations to dial in axle centering after a lift.

Frequently Asked Questions

What vehicles does this front swap kit fit?
It provides the brackets to fit a JK Dana 44 front axle into the TJ (1997-2006), LJ (2003-2006), XJ Cherokee (1984-2001), MJ Comanche (1985-1992), and ZJ Grand Cherokee (1993-1998).

What is the difference between the 9/16" hole and CAM slot brackets?
The CAM-slot lower control arm brackets accept factory-style adjustable cam bolts (as found on Rubicon axles) for caster adjustment, while the 9/16" hole brackets use a fixed bolt location. Choose the style that matches your control arms.

Do I keep the factory JK upper control arm mounts?
Yes. The kit retains the factory JK upper control arm mounts, so you only add the lower, shock, sway bar, track bar, and coil mounts.

Does it require welding?
Yes. This is a weld-on truss and bracket system. The brackets are jigged into the truss so they self-locate, but final installation requires welding to the axle housing.

Will the coil sit straight?
Yes. The coil relief is stamped into the coil bucket so the spring sits straight instead of bowing against a flat bucket.
