How to make a Peak Suspension warranty claim
- Peak expects installs to be done by a qualified mechanic experienced with suspension work; keep your install receipt
- Photograph the issue and gather your order details before removing anything
- Failed shocks get shipped to Peak for inspection; if Peak finds the failure wasn't a defect (neglect, install damage and so on), the owner pays for service, parts and shipping
- Shipping to and from Peak on warranty claims is the purchaser's cost

The Peak Suspension 2.5" DSC Coilover Explorer Kit | 17-22 Colorado ZR2 is a Peak Suspension part built for 2017-2022 Chevy Colorado. Peak designs and machines its suspension in the USA, and this piece is made for the platform rather than adapted from something generic.
Peak's 2.5" DSC line is its flagship coilover system: remote-reservoir aluminum shocks with Dual Speed Compression adjusters, so you can tune high-speed and low-speed compression separately instead of living with one compromise setting. More oil volume means the shocks run cooler and resist fade on long washboard or desert runs, and the coilovers are height adjustable so you can set the stance you want. Peak tunes the valving for each vehicle and builds the systems to be rebuilt and serviced, which matters if you plan to keep the truck and actually use it.
What you get and key features
- Precise fine tuning adjustments of high and low speed compression
- Improved on and off-road handling
- Increased protection against bottoming out
- High strength rod end designed for proper clearance
- Machined billet and anodized parts for high strength and long lasting lift
- Vehicle specific tuning for the most precise tuning
- Height adjustable for better off-road clearance and tire fitment up to 2.5"
- Pinch bolt coil adjuster to retain preload adjustments without compromising the threads
- (2) Front Coilovers
- (2) Rear Shocks
- Rear Lift Blocks
- (2) Front Reservoir Mounting Brackets
Fitment
Fits 2017-2022 Chevy Colorado. Not sure about your trim or drivetrain? Ask before you order.
Install notes
Front coilovers change ride height and suspension geometry, so plan on a professional alignment after install. Peak publishes install instructions and torque specs for its kits on its website.
Lead time and shipping
Peak works to keep its coilovers in stock, but when a kit is sold out, Peak's coilover production runs can take up to 8 weeks. Call or text us at (920) 249-7744 and we'll check current stock with Peak before you order. Peak ships direct from its shop, and its advice is a good one: don't book your install until the parts are in hand and you've checked the boxes.
Warranty
Peak covers the parts it manufactures with a limited lifetime warranty against defects for the original purchaser; Peak shocks carry one year, and springs, bushings and heim joints are wear items. Read the Peak Suspension warranty summary for details.

Peak Suspension 2.5" DSC Coilover Explorer Kit | 17-22 Colorado ZR2 FAQs
What does DSC mean on Peak shocks?
DSC stands for Dual Speed Compression. The adjusters let you tune high-speed compression (big hits, whoops) and low-speed compression (body roll, brake dive) separately, so you can set the shocks up for how you actually drive.
Do I need an alignment after installing this?
Yes. Any change to ride height or control arm geometry moves your alignment, so book a professional alignment right after install.
Do I need a differential drop?
Peak recommends a differential drop on non-ZR2 Colorado and Canyon trucks lifted more than about 2 inches, and on ZR2s lifted more than about 1.5 inches, to keep CV angles in check.
How long does Peak Suspension take to ship coilovers?
Peak works to keep its coilovers in stock. When a kit is sold out, Peak says coilover production runs can take up to 8 weeks. Call or text us at (920) 249-7744 and we will check current stock before you order, and wait until the parts arrive before you book an install appointment.
What warranty comes with Peak Suspension parts?
Peak covers parts it manufactures with a limited lifetime warranty against defects for the original purchaser. Peak shocks carry a one-year warranty, and springs, bushings and heim joints are treated as wear items. See our Peak Suspension warranty page for the full summary.
