2.25" Summit Series Adjustable Coilover Lift - 17-22 Colorado ZR2

Overview

Upgrade your off-road performance with the Peak Suspension 2.5” DSC Coilover Summit Kit, purpose-built for the 2017–2022 Chevy Colorado ZR2.

This all-in-one kit delivers a complete suspension overhaul, engineered to support larger tires, increased ground clearance, and next-level performance—both on and off the road. Whether you're crawling over rocks or cruising on pavement, the Summit Kit is designed to give you total control and confidence behind the wheel.

Installation is simple and seamless, with a bolt-on, OE-fit design that requires no cutting, welding, or permanent modifications. This makes it an ideal solution for enthusiasts looking to maximize capability without compromising factory quality or drivability.

Each 2.5” DSC Coilover includes remote reservoirs with independent high- and low-speed compression adjusters, allowing you to fine-tune damping for terrain, payload, or driving style. The increased oil volume of the reservoirs helps maintain cooler operating temperatures for consistent, fade-free performance.

Like all Peak products, the Summit Kit is hand-built using CNC-machined, billet aluminum components to ensure the highest quality and tightest tolerances. If you're looking for precision, durability, and versatility in one package—this is it.
