2027 GMC Canyon AT4X Overview
The 2027 GMC Canyon remains a midsize Crew Cab truck with a short bed, but the AT4X focuses on trail capability rather than maximum payload or luxury equipment. Its key advantage is a factory-installed combination of front and rear locking differentials, Multimatic DSSV dampers, off-road tires, and protective hardware. That gives the AT4X a more specialized purpose than the Elevation, AT4, or Denali trims.
The model year remains subject to an important specification distinction. Current-generation carryover information lists the 2.7L TurboMax at 310 horsepower and 430 pound-feet of torque, while a September 2026 drive report describes a revised turbocharger, higher-pressure fuel injection, piston changes, and output of 350 horsepower and 455 pound-feet. Treat the higher figures as reported until GMC publishes the final order guide.
Video Highlights:
- Reported output increases to 350 horsepower and 455 pound-feet of torque.
- The AT4X retains front and rear locking differentials.
- Factory 33-inch tires and 17-inch wheels support trail performance.
- Rock rails are standard and frame-mounted.
- The truck is designed to transition from difficult trails to normal roads.

AT4X Hardware and Trail Setup
The AT4X is built for drivers who regularly use technical trails, rocky approaches, and uneven terrain. The front and rear lockers are its defining mechanical feature. A front locker can help pull the truck through difficult sections when one front tire loses traction, while the rear locker supports controlled forward movement when the rear axle is unloaded or unevenly weighted.
The AT4X also uses Multimatic DSSV dampers and a lifted, widened off-road setup. The available information identifies 33-inch tires on 17-inch wheels, providing more sidewall than the larger wheels used by road-oriented trims. Standard frame-mounted rock rails add protection and can support optional accessory steps, although removable trail hardware should be inspected after difficult use.
Front Locker
Helps maintain front-axle traction when terrain unloads one wheel. Use it deliberately and disengage it when tight maneuvering no longer requires it.
Rear Locker
Supports steady forward movement over loose or uneven surfaces where a conventional open differential may spin one tire.
DSSV Dampers
Multimatic DSSV dampers provide the AT4X its specialized suspension identity and help balance control on rough terrain with road comfort.
Rock Rails
Standard frame-mounted rock rails protect the lower body. Accessory steps can be added, but trail clearance should remain a priority.
| AT4X feature | Practical benefit | Best operating priority |
|---|---|---|
| Front and rear lockers | Better traction in uneven terrain | Engage only when wheel slip or terrain demands it |
| 33-inch tires | More sidewall and trail clearance | Maintain appropriate tire pressure for conditions |
| 17-inch wheels | Supports a larger tire sidewall | Inspect wheels and sidewalls after rocky sections |
| Rock rails | Protects lower body areas | Keep rails clear of loose debris before road use |
| DSSV dampers | Improved off-road control | Use smooth inputs over repeated obstacles |
Approach obstacles slowly, select a controlled line, and use the lockers as traction tools rather than substitutes for careful tire placement.
Step-by-Step AT4X Trail Preparation
A capable truck still benefits from a repeatable preparation routine. The AT4X has the hardware for demanding terrain, but the driver must match the setup to the surface, slope, and obstacle. This process is useful before a rocky trail, deep ruts, or a long remote route.
Inspect the Truck
Check tire condition, sidewall damage, wheel security, fluid leaks, recovery points, and the condition of the frame-mounted rock rails. Remove loose cargo from the bed and cabin.
Choose the Drive Setting
Select the appropriate four-wheel-drive and terrain setting before reaching the obstacle. Avoid changing settings while the truck is placed awkwardly on a steep or uneven section.
Pick the Line
Walk or visually inspect the obstacle when practical. Favor a line that keeps the truck balanced, protects the underbody, and avoids unnecessary cross-axle loading.
Use Lockers Deliberately
Engage the front or rear locker when traction loss requires it. Keep steering and throttle inputs smooth, especially when the front locker is active.
Inspect After the Section
Once clear of the obstacle, check tire sidewalls, rails, suspension components, and visible underbody areas. Reassess before continuing to the next difficult section.
| Preparation stage | What to check | Why it matters |
|---|---|---|
| Before departure | Tires, rails, fluids, recovery equipment | Prevents avoidable trail interruptions |
| Before an obstacle | Line, clearance, drive setting | Reduces impact and unnecessary wheelspin |
| During the obstacle | Speed, steering, throttle | Maintains control and limits component shock |
| After the obstacle | Tires, rails, underbody | Catches damage before it becomes a larger problem |
The most effective AT4X setup is controlled rather than aggressive: lower speed, accurate tire placement, and steady throttle usually preserve more traction than momentum alone.
Trim Comparison and Powertrain Context
The AT4X sits between the standard AT4 and the luxury-focused Denali in purpose, not simply in price. All four expected trims use the same Crew Cab short-bed body, while the main differences involve suspension tuning, wheel and tire choices, protective equipment, and interior materials.
The AT4X is the clear choice for buyers who prioritize factory off-road hardware. The Denali is better suited to buyers who want upscale materials and larger wheels. Elevation offers the lowest entry point, while AT4 provides an off-road-oriented middle ground without the full AT4X equipment package.
| Trim | Primary role | Notable equipment | Best fit |
|---|---|---|---|
| Elevation | Entry and daily use | 11.3-inch touchscreen, 11-inch driver display, off-road-tuned suspension | Buyers wanting a practical midsize truck |
| AT4 | General off-road use | Wider track, additional clearance, 17-inch wheels, all-terrain tires | Owners who leave pavement occasionally |
| AT4X | Serious trail capability | Front and rear lockers, DSSV dampers, 33-inch tires, rock rails | Technical trail and obstacle-focused driving |
| Denali | Luxury flagship | Real wood trim, Jet Black and Teak leather, 20-inch wheels | Road comfort and premium cabin materials |
The single-engine strategy simplifies the lineup. There is no listed V6, diesel, or hybrid option for the third-generation Canyon. The current carryover specification uses the 2.7L TurboMax with an eight-speed automatic, while the reported 2027 update could raise output substantially.
| Powertrain question | Current information |
|---|---|
| Engine choice | 2.7L TurboMax turbocharged four-cylinder |
| Carryover output | 310 horsepower and 430 pound-feet |
| Reported 2027 output | 350 horsepower and 455 pound-feet |
| Transmission | Eight-speed automatic |
| Drivetrain | Rear-wheel drive or four-wheel drive, depending on configuration |
| Alternative engines | No confirmed V6, diesel, hybrid, or plug-in hybrid |
Choose AT4X for hardware you will use on difficult trails. Choose Denali for cabin materials and road-focused presentation. The badges represent different priorities, not just different equipment levels.
Buying Checklist, Towing, and FAQs
The 2027 AT4X is attractive because it combines midsize dimensions with serious factory trail equipment. It can fit between trees and narrow trail features more easily than a full-size truck, while still returning to paved roads with a comparatively comfortable ride. The tradeoff is the limited Crew Cab short-bed configuration and the possibility that final 2027 specifications may change before ordering.
The drive report also identifies 6,000 pounds as the towing capacity for the ZR2, while the base truck is cited at 7,700 pounds. Those figures should not automatically be assigned to the AT4X without a final GMC specification sheet. Buyers should verify the exact tow rating for the selected configuration, equipment, and hitch setup.
Before Ordering an AT4X:
- Confirm whether the final engine output is 310 hp or the reported 350 hp
- Verify the exact 2027 MSRP and available packages
- Confirm the AT4X tow rating for the chosen configuration
- Check tire, wheel, locker, DSSV damper, and rock rail equipment
- Decide whether a 5-foot-2-inch bed meets your cargo needs
| Buying factor | What to verify | Why it matters |
|---|---|---|
| Engine output | Final 2027 order-guide figures | Separates carryover data from reported updates |
| Pricing | GMC-published MSRP | 2027 pricing was not available in the reference material |
| Tow rating | Exact AT4X configuration | Ratings can vary by trim and equipment |
| Bed size | 5-foot-2-inch short bed | No long-bed configuration is listed |
| Trail equipment | Lockers, DSSV dampers, rails, tires | Confirms the truck matches your intended use |
For broader model-year timing and trim information, consult the related 2027 GMC Canyon release date, redesign status, and trims guide. It identifies expected ordering around September 2026 and production beginning in October 2026, while also noting that refresh timing and pricing require official confirmation.
Q: What makes the 2027 GMC Canyon AT4X different from the AT4?
The AT4X adds the most specialized off-road hardware in the lineup, including front and rear locking differentials, Multimatic DSSV dampers, 33-inch tires on 17-inch wheels, and standard frame-mounted rock rails.
Q: How much power does the 2027 GMC Canyon AT4X have?
Carryover information lists the 2.7L TurboMax at 310 horsepower and 430 pound-feet. A September 2026 drive report describes a revised engine producing 350 horsepower and 455 pound-feet. Confirm the final GMC order guide before ordering.
Q: Does the 2027 GMC Canyon AT4X have front and rear lockers?
Yes. The AT4X is identified with both front and rear locking differentials, giving it a major traction advantage over trims without the same locker equipment.
Q: What bed and cab configuration does the AT4X use?
The third-generation Canyon is listed as a Crew Cab with a 5-foot-2-inch bed. The available reference information does not identify an extended-cab or long-bed AT4X configuration.
The AT4X makes the strongest case when trail capability is a primary requirement. Before committing, verify the final 2027 power figures, pricing, towing rating, and package availability through GMC’s published order information.
