GM 99-18 GM 1500 Silverado/Sierra Hub Spacers



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

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.
