Jeep Wrangler JL Grimm Offroad Hardware Upgrade Kit

The Grimm Offroad Hardware Upgrade Kit Works for All Suspension Components

The Jeep Wrangler JL uses fully threaded bolts for all its suspension components. A fully threaded bolt will not provide the best fit for components like control arms or track bars where the inner sleeve of those components interfaces with the threaded portion of the bolt. Over time, these bolts can loosen up and cause the threads of the bolt to dig into the inner sleeve causing wear on both the threads of the bolt and the inner sleeve resulting in a sloppy fit. This kit replaces the fully threaded bolts with shouldered bolts to provide a nice smooth surface for the suspension components to interface with.

Replacement Hardware for All 8 Control Arms

The Grimm Offroad Hardware Upgrade Kit includes Grade 10.9 Metric replacement hardware for all 8 control arms, front and rear track bars, and lower shock mounts. All hardware is the proper length and the lower shock mounting bolts have been reduced in length compared to stock to prevent issues with them contacting the front lower control arms or catching on obstacles in the rear. The high-strength OEM flag nuts are retained for ease of installation. For increased longevity, everything is finished with yellow zinc to protect against corrosion.
