Details

The aluminum counterpart to our steel Crawl-tier XJ front upper arms — 1.5" solid 7075-T6 bar, double-threaded like the rest of the set: a forged Rock Jock Johnny Joint at the frame end and a steel U-bracket at the axle end, welded to a threaded shank so both ends thread into the arm. Same front upper as our TJ/LJ application. Double-adjustable with milled wrench flats to set caster with the lowers.

Notes

• Hardware is included with your arms. If you ever need replacements down the road, the matching kit is available separately.
• Apply anti-seize to the aluminum-to-steel joint threads on install — cheap insurance against galling on any aluminum arm.
• Running a lift? The front set (AL-J-XJ-FS4) pairs these with the matching front lowers to do the whole front in one job.
• Front control arms only — the XJ and MJ are leaf-sprung in the rear.
