Details

The complete aluminum front end for the TJ/LJ — both front lower arms and both front upper arms in one box. Lowers run 1.75" solid 7075-T6, uppers run 1.5" solid 7075-T6, all double-threaded on forged Rock Jock Johnny Joints (the front uppers use a steel U-bracket at the axle end). Solid 7075 construction takes real weight off the front of the Jeep versus our steel arms — the full 8-arm aluminum set runs about 20–25% lighter than the steel set.

Includes

  • 2 assembled aluminum front lower arms (AL-J-TJLJ-FL2)
  • 2 assembled aluminum front upper arms (AL-J-TJLJ-FU2)
  • All forged Rock Jock Johnny Joints and steel U-brackets, installed
  • Mounting bolts and jam nuts for all four arms

Specs

  • Front lower bar — 1.75" solid 7075-T6 aluminum
  • Front upper bar — 1.5" solid 7075-T6 aluminum
  • Joints — greaseable forged Rock Jock Johnny Joints (front uppers use a steel U-bracket at the axle end)
  • Adjustable length — all four arms, for front-axle alignment and caster
  • Finish — powder coat or raw aluminum
  • Lift range — 0–6 in.
  • Made in the USA
  • You break it, we replace it
  • Wear items (joints) — covered for 18 months

Notes

  • Apply anti-seize to the aluminum-to-steel joint threads on install.
  • Doing the whole Jeep? The complete 8-arm set (AL-J-TJLJ-CS8) adds the rear arms and saves over buying front and rear separately.

Parts

  • Forged Rock Jock Johnny Joint, right-hand — CE-9114 (front lowers).
  • Forged Rock Jock Johnny Joint, left-hand — CE-9114L (front lowers).
  • Forged Rock Jock Johnny Joint, left-hand — CE-9112NSPL (front uppers).
  • Replacement hardware kits — CRL-J-TJLJ-FL2-HWK, CRL-J-TJLJ-FU2-HWK.

Fits

  • Jeep Wrangler TJ (1997–2006)
  • Jeep Wrangler Unlimited LJ (2004–2006)

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

The quality and durability of the arms are the best. They are super heavy duty. And lifetime warranty is crazy
