Pacbrake Alpha HD Rear Air Suspension Helper Springs Kit for 2007-2018 Chevy Silverado & GMC Sierra 1500 (Including 2019 LD/Limited)

Eliminate severe rear-end sag, trailer sway, and harsh bottoming out during heavy towing with the Pacbrake Alpha HD Rear Air Suspension Kit. Carrying heavy bed payloads, slide-in campers, or high-tongue-weight trailers strains stock leaf springs, causing light front-end steering feel and unstable braking dynamics.

Built using heavy-duty double-bellows air springs with durable composite end caps, this air helper spring system delivers up to 5,000 lbs of load-leveling assistance. According to SEMA chassis load engineering benchmarks, supplemental air helper springs maintain vehicle levelness to ensure proper headlight aiming and optimal front-tire pavement contact under maximum payload. Engineered to withstand deep winter freezes, harsh road salt exposure, and rough off-road washboards, Pacbrake Alpha HD springs feature independent pneumatic inflation lines to level uneven cargo loads with complete confidence.
