Details

The complete aluminum rear end for the TJ/LJ — both rear lower arms and both rear upper arms. Lowers run 1.75" solid 7075-T6, uppers run 1.5" solid 7075-T6, all fully aluminum and double-adjustable on forged Rock Jock Johnny Joints. Solid 7075 takes real weight off the rear 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 rear lower arms (AL-J-TJLJ-RL2)
  • 2 assembled aluminum rear upper arms (AL-J-TJLJ-RU2)
  • All forged Rock Jock Johnny Joints, installed
  • Mounting bolts and jam nuts for all four arms

Specs

  • Rear lower bar — 1.75" solid 7075-T6 aluminum
  • Rear upper bar — 1.5" solid 7075-T6 aluminum
  • Joints — greaseable forged Rock Jock Johnny Joints, both ends on all four arms
  • Adjustable length — all four arms, for pinion angle and wheelbase
  • 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 front arms and saves over buying front and rear separately.

Parts

  • Forged Rock Jock Johnny Joint, right-hand — CE-9114 (rear lowers).
  • Forged Rock Jock Johnny Joint, left-hand — CE-9114L (rear lowers).
  • Forged Rock Jock Johnny Joint, right-hand — CE-9112NSP (rear uppers).
  • Forged Rock Jock Johnny Joint, left-hand — CE-9112NSPL (rear uppers).
  • Replacement hardware kits — CRL-J-TJLJ-RL2-HWK, CRL-J-TJLJ-RU2-HWK.

Fits

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

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
