There’s no question: The off-road vehicle market is hot. For the past several years, OEM brands have been releasing new and innovative trail-ready rigs that can go just about anywhere straight from the factory. But if you want something even more custom and capable, that’s where aftermarket manufacturers come in.
The team at Peak Suspension recently unveiled an ultra-modified 2021 Chevrolet Colorado ZR2 that has great overland upgrades.
What is a ZR2?
Chevrolet first introduced the Colorado ZR2 as a 2017 model. At the time it was a game changer, as it provided off-road enthusiasts an excellent alternative to a Jeep or more expensive full-size truck. Building on the success of the ZR2, Chevrolet teamed up with aftermarket parts provider American Expedition Vehicles (AEV) to produce the 2019 Colorado ZR2 Bison.
For 2021 the ZR2 lineup receives a mild refresh. From the factory, every ZR2 and ZR2 Bison will come equipped with locking front and rear differentials, 2-inch lift, Multimatic DSSV performance shocks and off-road bumpers — among other unique features.
While it’s a great truck right from the dealer lot, there are several things that hold back the true capability of a ZR2. Most notably, the tires are rather small for an off-road truck of its size at just less than 31 inches. Plus, despite the 2-inch lift, the ZR2 still suffers from lack of ground clearance in part due to rear shock mounts that hang well below the rear axle.
The 2021 Peak Suspension ZR2
This truck is not like any other ZR2 out there. These modifications make a stock ZR2 much more capable. Nick Psomas from Peak Suspensions sent us the following list of modifications that have been made to their 2021 ZR2.

The bottom line on the Peak Suspension ZR2
The Peak Suspensions 2021 ZR2 is an incredible truck. While all the modifications work really well as a whole, my favorite upgrade has to be the 35-inch tires. That is a massive upgrade over stock, and combined with the stock ZR2 lockers, it makes for an incredible off-roader. Currently, there is no midsize truck that comes stock with 35s.
While this specific build may not be for sale, if you are looking to build your own overland off-road rig, all the parts featured are available for sale separately.
At the end of the day, with so much going on in the off-road truck market — both with OEM and aftermarket manufacturers — there has never been a better time to hit the trail.
