Product Description

The King Shocks 25001-193 rear piggyback reservoir shocks are engineered for 2017-2025 Chevy Colorado and GMC Canyon 4WD models, including ZR2, AT4, Denali, Trail Boss, and Elevation trims. Built around a 2.5" aluminum shock body with a high-volume piggyback reservoir, these shocks dramatically improve rear-end control for daily driving, towing, and off-road conditions alike.

Designed for vehicles with up to 2" of rear suspension lift, these shocks work perfectly on stock-height trucks or those with mild rear lift setups. The piggyback design enhances cooling and resists fade under extended compression cycles. Tuned to match factory dynamics and capable of being rebuilt or revalved, the 25001-193 series provides lasting, upgradeable performance. For even greater adjustability, the 25001-193A version includes compression tuning knobs.

Fitment is confirmed for 2017-2025 4WD Colorado and Canyon models with compatible rear ride height. Not for 2WD vehicles or trims without off-road suspension packages. These are rear-only shocks and should be paired with proper front suspension upgrades for best results. Not emissions-sensitive.
