The upper link of the three-link runs from the driver's side inner framerail to a mount above the axlehousing. The axle, a Dynatrac ProRock 44, has a JK-style bushing on top, but since we're using a different style upper joint we fabricated a steel bushing and outer link mount to double-shear the joint. The links are made of 13/4x0.188-inch heat-treated 4130 chromoly.
