🧾 Overview
The Grimm OffRoad Hardware Upgrade Kit is designed to address a common weakness in the factory suspension hardware found on Jeep Wrangler JK and JKU models. Factory bolts can develop excessive movement or loosen over time, particularly on lifted Jeeps running larger tires and aftermarket suspension components.
This kit replaces the factory hardware with oversized, higher-strength Grade 8 replacement hardware featuring partially threaded, shouldered bolts. The design provides a tighter mounting fit for the suspension components, helping reduce unwanted movement and hardware-related wear.
Designed for all four lower control arms and both front and rear track bars, this kit is a practical upgrade for Jeep owners looking to improve suspension mounting security and durability.
✔ Oversized, higher-strength replacement bolts
✔ Grade 8 hardware for improved strength
✔ Partially threaded, shouldered bolt design
✔ Includes hardware for all four lower control arms
✔ Includes front and rear track bar hardware
