The current 226105 replaces the older 26105 listing. It is a generation-specific hard-folding cover for the long-bed first-generation Colorado and Canyon, not a universal midsize-truck cover.
Fitment first
What to confirm before buying
Part 226105 is listed for 2004-2013 Chevrolet Colorado and GMC Canyon trucks with the 72.8-inch bed, commonly described as 6 ft 1 in. The replacement relationship is specific: 226105 supersedes the old 26105 reference. That does not make either number interchangeable with G2 covers for a short bed or a later Colorado or Canyon generation.
Measure the bed between the inside of the bulkhead and the inside of the closed tailgate. Do not round a result to six feet and stop there; compare it with 72.8 inches. Then confirm the truck generation and model in the manufacturer's application guide. Some older Isuzu I-Series applications are documented in the source record, but they still require an exact vehicle and bed check.
Look along the upper bed rails for plastic caps, drop-in liner edges, toolbox brackets, or repairs that alter the clamp area. The intended installation is no-drill on the correct bed, which depends on the rails and clamps meeting the surfaces they were designed for. A short bed, a later body, or a blocked clamping flange is a fitment issue, not something to solve by trimming the cover.

How this accessory works in practice
BAKFlip G2 part 226105 is the replacement reference for the older 26105 number. It is a long-bed, first-generation Colorado and Canyon application rather than a generic midsize-truck cover. The assembly combines aluminum hard panels with a folding layout, automatic latches, perimeter sealing, and rails that sit low along the bed sides. It is intended to provide a rigid closed surface while preserving full bed access when folded forward.
The G2 can be operated from either side through release cables beneath the panels. With the cover down and the tailgate locked, the latch system is not normally reachable from outside the bed. For larger loads, the sections fold toward the cab and prop rods hold the assembly upright. Dual drain tubes direct channel water toward bed exits, and the published legacy specification allows up to 300 pounds distributed evenly over the closed cover.
Daily use and ownership
Closing the panels in sequence engages the automatic latches. The quick-release cables remain underneath and can be reached after the tailgate is opened, from either side of the bed. When the final panel is down and the tailgate is locked, cargo gains a rigid visual and physical barrier. Confirm each side has latched rather than relying on the sound from only one catch.
The cover supports three useful bed states: closed for covered cargo, partly folded for access to the rear portion, and upright for larger items. The integrated buckles or prop hardware must be used for the selected open position. When upright, the product information says the cover preserves complete bed access without covering the third brake light, but the driver still needs to check rearward visibility.
Water captured by the side channels is sent through two drain tubes, while perimeter and tailgate seals reduce direct entry. Expect water management, not a sealed cargo vault. Keep paper goods, electronics, and textiles in closed containers, and prevent loose cargo from pressing upward against the panels or interfering with release cables.
Installation and setup
Clean the bed rails and bulkhead edge, identify left and right rails, and locate suitable drain exits before mounting anything. Set both rails against the bulkhead reference and attach the clamps loosely. Their upper surfaces must remain level and parallel; a rail that climbs toward the tailgate will change latch height along the full cover.
Place the folded G2 at the front, unfold all panels, and study the gaps before tightening. Equal side overlap, square panel edges, and consistent contact at the rear seal show that the rail spacing is close. A cover that lies diagonally usually points to uneven rail placement, so correct the base alignment instead of pulling the final panel sideways.
Test-fold the complete assembly, engage the latches, raise it onto the prop rods, and cycle the tailgate. Once every position works without binding, tighten the clamps to the instructions. Route both drain tubes downward without kinks, confirm discharge with a small water test, and inspect all clamps again after the cover has settled through several open-close cycles.
Care and maintenance
Wash the painted aluminum and vinyl surfaces with mild soap and water, paying attention to dust packed beside the hinges. Wipe the rail ledges, latch contacts, and perimeter seals before folding the cover so grit is not trapped between panels. Keep chemical solvents, abrasive polish, and petroleum-based dressings away from the seals unless the manufacturer specifically approves them.
Check drain flow, clamp seating, release-cable condition, and prop-rod attachment at regular intervals. An evenly distributed load rating is not permission to stand or place a concentrated object on one panel; point loads can exceed the panel design. Remove snow or debris progressively and investigate any new sag, loose latch, or change in tailgate pressure before continued use.
Buy it when
- You have a verified first-generation 72.8-inch Colorado or Canyon bed.
- You want a hard cover that can expose the complete bed.
- Tailgate-controlled latches fit your cargo-security needs.
- The bed provides clear clamp surfaces and drain exits.
Skip it when
- Your truck has a short bed or a later body generation.
- You are treating 226105 as a universal replacement for any 26105 listing.
- A permanent toolbox occupies the forward folding or rail space.
- Your loads would place concentrated weight on the closed panels.
Frequently asked questions
What is the relationship between 226105 and 26105?
The rebuilt catalog identifies 226105 as the replacement for legacy part 26105 in the first-generation Colorado and Canyon long-bed application. Verify the replacement through the vehicle selector because the old number alone does not prove bed or generation fit.
Does this G2 fit a nominal six-foot short bed?
It is documented for the 72.8-inch long bed. Names such as six-foot bed are often rounded and can conceal a meaningful difference. Use an inside bulkhead-to-tailgate measurement and the exact truck application rather than the rounded description.
Can 300 pounds be placed anywhere on the cover?
No. The published figure applies to weight spread evenly across the closed cover. A person, machine foot, or other small contact area creates a concentrated load. Follow the manufacturer's restrictions and use the truck bed for cargo support whenever possible.
Why does the cover look diagonal after unfolding?
The source installation guidance points to uneven rail placement as the usual reason. Loosen the clamps, square both rails to the bulkhead, compare side-to-side spacing, and test the panels again before making any adjustment to latch components.
