The King Shocks 2.5in Piggyback Reservoir Rear Shocks fit the 2015-2019 GMC Sierra 2500HD and deliver race-bred damping with on-the-fly compression adjustment.

Install Difficulty: Professional Install Only
Bolts to factory rear shock mounts and requires routing and securing the piggyback reservoirs; typically installs in 60-90 minutes per side on a vehicle lift. Professional alignment recommended after any suspension modification.

Product Overview

Sold as a pair, these rear shocks use a 2.5in diameter body with a piggyback remote reservoir to increase oil capacity and resist fade under heavy load or hard trail use.

The adjuster lets you dial in compression damping for payload, towing, or off-road conditions without removing the shock.

Each kit is custom-tuned by King to match the Sierra 2500HD chassis for an optimized damping curve and ride quality.
