1/2" steel lasered/machined hub and caliper spacers to make lower balljoint clearance on 99-Present GM 1500 trucks running 16" brakes with flipped lower balljoints (common to aftermarket control arms).
Includes longer hub bolts (Class 10.9 M14-1.5 x 80mm such as Fastenal 11114031) as well as longer caliper bolts for use with the 16" brake kits such as Wilwood 140-8992
NOTE: It is highly recommended to TIG weld the spacers to the spindle using 312 filler rod, so as to reduce pressure on the hub bolts, as is the factory situation.
