The factory fully threaded bolts on a JT suspension work loose over time, and the threads dig into the inner sleeves of control arms and track bars. The fit goes sloppy and both parts wear.
This Grimm OffRoad kit replaces them with Grade 10.9 metric shouldered bolts that give the sleeves a smooth surface. It covers all 8 control arms, the front and rear track bars and the lower shock mounts, and the lower shock bolts are shorter than stock to avoid contact.
Swap the bolts one joint at a time and reuse the OEM flag nuts.
