Shop now for Spindle Parts for 2020-current Chevy Silverado and GMC Sierra 3500 series Trucks with AAM 12" Rear Axles.
2020-up GM 3500 trucks with AAM 12" Full Float Rear Axles use a single Spindle Nut held in place by a solid Key and Retainer Ring. This type of wheel bearing retention is quite reliable when properly installed, but end-play adjustments are somewhat coarse.
