Most trucks with off-road trim packages are styling exercises with a lifted suspension and all-terrain tires. The Chevy Colorado ZR2 is a different category entirely - a factory-built rock crawler and trail truck that has won Baja races and earned genuine respect from the off-road community. For Bergen County buyers who actually want to use their truck off-road, understanding what the ZR2’s hardware actually does separates it from imitators.
Bottom Line: The Colorado ZR2 is one of the most capable off-road trucks ever built, with DSSV suspension, front and rear locking differentials, and rock sliders as standard equipment - not upgrades.
- DSSV (Dual Spool Valve) dampers from Multimatic are the same technology used in race cars
- Standard front and rear electronic locking differentials - many competitors offer only rear
- 10.8 inches of ground clearance enables genuine rock crawling and deep trail use
- The Bison package adds underbody armor for the most severe terrain use cases

The DSSV Suspension: Why It Matters
The Multimatic DSSV (Dual Spool Valve) dampers are the ZR2’s most technically significant feature. Most production trucks use conventional mono-tube or twin-tube shock absorbers. DSSV dampers use a more sophisticated hydraulic circuit that allows independent tuning of low-speed and high-speed damping forces.
In practical terms, this means the ZR2 absorbs slow trail obstacles (rocks, logs, whoops) with a different suspension response than it uses for high-speed desert running. The truck doesn’t have to compromise between soft-trail-crawl compliance and high-speed stability - the DSSV manages both.
For Bergen County buyers who take day trips to trails in the Catskills, Delaware Water Gap, or the Appalachian foothills in western New Jersey, the DSSV suspension makes the ZR2 genuinely capable rather than a truck that gets stuck and causes more damage than it clears. The same technology appears in the Chevrolet Camaro Z/28 and various purpose-built race vehicles.
Front and Rear Locking Differentials: The Capability Difference
Most capable trucks offer a rear locking differential as a premium option. The ZR2 comes standard with both front and rear electronic locking diffs.
A rear lock alone prevents rear wheel spin by connecting both rear wheels to spin at the same speed. When one rear wheel lifts off the ground or loses traction, power transfers to the other. It’s effective on moderate trails and steep hill climbs.
A front locker changes the ZR2’s capability on severely uneven terrain - rock gardens, angled camber crossings, and technical switchbacks where front wheels need independent traction control. With both diffs locked, the ZR2 behaves differently from any truck that offers only a rear locker, maintaining momentum through obstacles that stop conventional 4x4s.
For most Bergen County off-roaders who trail ride in the northeast and mid-Atlantic, the front locker gets used infrequently. But it’s there when you need it, and no aftermarket upgrade can replicate factory-calibrated locker engagement at the trail head.
"The ZR2 buyers I work with in Paramus are serious - they're driving to Moab, doing Delaware Water Gap runs, or towing trail bikes to the Catskills. When they see the front locker and DSSV suspension in a factory vehicle at this price, the Tacoma TRD Pro and Ranger Raptor comparison gets complicated quickly."

Rock Sliders and Underbody Protection
The ZR2 includes rock sliders as standard equipment - these are steel tubes that protect the frame rails and cab corners from rock strikes during off-camber trail sections. Aftermarket rock sliders on competitor trucks cost $800-$1,500 installed and often don’t match the structural integration of factory equipment.
Wheel flares on the ZR2 are functional, not just styling - they allow the wider track width and lifted suspension geometry without tire rub during full suspension articulation. The 1.8-inch wider front and rear track versus the standard Colorado improves stability both off-road and during road driving.
The ZR2’s standard underbody includes transfer case protection and a standard skid plate. The Bison package, available as a factory option, upgrades this significantly:
- Five stamped skid plates protecting fuel tank, transfer case, oil pan, and front suspension
- ZR2 Bison-specific rocker protection
- AEV (American Expedition Vehicles) front and rear bumpers with recovery points
The Bison is worth adding for buyers who plan to run technical terrain regularly. For drivers who use the ZR2 primarily as an extreme weather/light trail truck in the northeast, the standard ZR2 underguard is adequate.
ZR2 vs. Trail Boss: Choosing Your Colorado Off-Road Level
The Trail Boss is a separate off-road configuration below the ZR2 that shares the Z71 off-road package heritage. It offers a 2-inch suspension lift, Rancho shocks (not DSSV), skid plates, and off-road tires - a capable combination for moderate trail use at a lower price point than the ZR2.
The hardware distinction is clear: Trail Boss for overlanding, camping access roads, and light to moderate off-road. ZR2 for serious technical terrain, competitive off-road events, and buyers who want factory hardware that doesn’t need aftermarket augmentation.
The Trail Boss typically runs $8,000-$12,000 less than the ZR2. For Bergen County buyers who take the truck to the beach at Sandy Hook or explore state forest roads in Wharton State Forest, the Trail Boss may be the better financial decision. For buyers who will actually use the DSSV suspension and front locker, the ZR2’s premium is justified equipment cost, not marketing.

Frequently Asked Questions
Is the ZR2 comfortable to drive as a daily vehicle in Bergen County? Yes, with some caveats. The DSSV suspension is noticeably firmer than the standard Colorado on pavement - the aggressive shock calibration that handles high-speed off-road also transmits road imperfections more directly. It’s not uncomfortable, but perceptibly different from the standard Colorado’s ride. Most ZR2 owners accept this as the expected tradeoff.
What fuel economy should ZR2 owners in Bergen County expect? The ZR2 with the V6 returns approximately 17-18 MPG combined in real-world driving. The larger tires, lifted suspension, and AWD add up to real fuel consumption - budget for it. Route 17 and Garden State Parkway commuting doesn’t do the ZR2 any fuel economy favors.
Can the ZR2 tow as much as the standard Colorado? The ZR2 is rated to tow up to 7,700 lbs when properly equipped - slightly less than the standard Colorado V6’s 7,700 lb rating but essentially the same. The ZR2’s suspension geometry is optimized for off-road articulation, which slightly affects towing stability at maximum loads. For normal trailer towing in Bergen County, the ZR2 handles it confidently.
Is the ZR2 available with the diesel engine? The diesel engine option availability varies by model year on the ZR2 - confirm current availability with Paramus Chevrolet. Diesel ZR2 combinations offer significantly better torque and fuel efficiency for trail use.
Does the ZR2 need premium fuel? No - the V6 gasoline engine uses regular 87-octane fuel. No premium fuel requirement or recommendation.
