The King Shocks 2.5in Piggyback Reservoir Rear Shocks fit the 2020-2025 Chevy Silverado 2500HD and deliver custom-tuned OEM Performance Series damping for serious off-road and heavy-haul duty.

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

Product Overview

This pair of rear shocks uses a 2.5in diameter body with a piggyback remote reservoir to increase oil capacity and resist heat fade under repeated hard hits.

Each shock includes an external compression adjuster, letting you fine-tune low-speed damping for payload, trail terrain, or daily ride comfort.

King develops the damping curve through real-world testing on the Silverado 2500HD chassis, so the kit bolts on with factory-matched valving rather than generic off-the-shelf tuning.
