The JL and JT utilize fully threaded bolts for all suspension components.
A fully threaded bolt does not provide the best fit for components such as control arms or track bars where the inner sleeve of those components interfaces with the threaded portion of the bolt.
Over time, these bolts may loosen and cause the threads of the bolt to dig into the inner sleeve, resulting in wear on both the threads of the bolt and the inner sleeve, which leads to a sloppy fit.
This kit replaces the fully threaded bolts with shouldered bolts to create a smooth surface for the suspension components to interface with.
This 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 correct length, and the lower shock mounting bolts have been shortened compared to stock to avoid 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 installation ease.
High strength grade 10.9 shouldered bolts, washers that won’t deform, yellow and clear zinc surface finish, distorted thread lock nuts, and reuses OEM high strength flag nuts where applicable.
NOTE: Zinc surface finish color may not match images due to hardware availability.
