The JL Replacement HD Rear LCA Frame Bracket is Artec Industries' heavy-duty upgrade for the factory rear lower-control-arm mount on the Jeep Wrangler JL — one of the first things to bend, crush, or tear when a big tire hangs up on a rock or a lifted rig loads the suspension hard. Formed from 1/4" boxed steel plate and engineered off Jeep's own 3D data, it restores a straight, strong pickup point and adds a built-in skid so the joint keeps working instead of getting hammered flat.
Key Features
- 1/4" boxed steel plate construction for real impact resistance at a high-load suspension point
- CNC laser cut and CNC bent from factory 3D OE data for a precise, repeatable fit
- Integrated bottom skid protects the lower control-arm joint without restricting its movement
- Top-access grease fitting keeps routine maintenance easy after install
- 2.625" mounting width with 9/16" bolt holes to match the factory lower arm
- Made in the USA
Fitment & Compatibility
Fits the Jeep Wrangler JL (2018 and up) at the rear lower-control-arm frame mount. This is a weld-in replacement bracket intended to reinforce or repair the factory rear LCA pickup; it pairs naturally with a long-arm or mid-arm suspension build. Confirm your existing arm hardware matches the 9/16" bolt and 2.625" mount width before install.
