This is a part to reduce the "rattling" of the front suspension on the Mini-Z 4x4. It was created as part of an improvement to address the issue of "becoming difficult to turn when a load is applied." Compatible with Jimny, 4Runner, Wrangler, Defender, and Land Cruiser 300. There are no instructions, so please refer to the following videos: [Upper Arm Measures] youtu.be/SRDxeV40IYA [Rod End Measures] youtu.be/y6-qI-HEgYg [Assembly of Parts] youtu.be/Ez9KbFUR33g The parts can be installed without modification, but due to the tight dimensional tolerances, some adjustment may be required. The product is made using a layered 3D printer. The material is PLA+, and the layer thickness is 0.1mm. Packaging will be "plastic bag + envelope". Thank you.
