WeatherTech 440031-440612 FloorLiners for GM Trucks and SUVs

Critical Fitment Restrictions

• Silverado and Sierra applications require a Crew Cab.
• Does not fit Regular Cab or Extended Cab pickups.
• The 2007 application is for Silverado Classic and Sierra Classic models.
• Does not fit the redesigned 2007 Silverado or Sierra new-body trucks.
• Does not fit trucks with a floor-mounted manual-transfer-case shifter.
• Designed for vehicles with factory carpet.
• Does not include third-row or cargo-area protection.
• Check the front seating and center-console configuration.
• Confirm part numbers 440031 and 440612 before purchasing.

Part 440031 is the first-row set, while 440612 covers the appropriate second-row floor. The combination only works when both individual pieces match the vehicle.

How to Identify a 2007 Classic Truck

The easiest way to avoid ordering the wrong liner for a 2007 Silverado or Sierra is to identify the body generation.

Check the VIN, door-jamb production label and exact model name. Don’t rely entirely on the registration paperwork, which may simply say “2007 Silverado” while withholding the only detail you actually need.

Product Specifications

What Comes in the Set?

The package includes:

• Driver-side front FloorLiner
• Passenger-side front FloorLiner
• Vehicle-specific second-row FloorLiner
• Black finish

The set does not include a third-row liner, cargo liner or replacement carpet. Suburban and Yukon XL owners needing rear cargo protection must purchase the corresponding cargo-area product separately.

Laser-Measured GMT800 Coverage

WeatherTech digitally measures the vehicle floor so the liners follow the transmission tunnel, console, seat mounts, door sills and rear footwell.

The raised edges and molded channels help contain:

• Rainwater and snowmelt
• Mud and road salt
• Worksite dirt
• Sand and gravel
• Food and drink spills
• Hunting and outdoor debris
• Fluids carried into the cab on work boots

This is particularly useful in crew-cab trucks, where the rear floor often gets treated as equal parts passenger compartment, toolbox and mobile storage locker.

WeatherTech describes its FloorLiners as covering the bottom, front, back and sides of the footwell. Current product information is available through the official WeatherTech floor-mat catalog.

HDTE Material and Fluid Channels

The High-Density Tri-Extruded construction combines a rigid core with textured upper and lower surfaces. This allows the liners to retain their molded shape while helping them grip the carpet and provide traction beneath passengers’ shoes.

Advanced channels direct fluid and debris toward lower reservoirs. This helps keep collected water away from footwear and reduces movement during ordinary driving.

The raised edges aren’t infinitely tall, so remove major spills promptly. A truck cab is useful for many things. Becoming a decorative indoor pond isn’t one of them.

Installation

Installation is normally tool-free:

1. Remove every existing floor mat.
2. Vacuum loose debris from the factory carpet.
3. Install the driver-side front liner.
4. Engage all available factory retention points.
5. Install the passenger-side liner.
6. Position the rear liner beneath the front seats.
7. Move the seats through their full adjustment range.
8. Verify accelerator and brake-pedal clearance.
9. Confirm that the liner doesn’t obstruct seat tracks or a floor shifter.

Never place the FloorLiners on top of factory mats. Stacked mats can move or interfere with pedal operation.

Cleaning and Maintenance

Remove the liners from the vehicle before washing them. Shake out loose dirt, rinse with water and use mild detergent or a dedicated floor-liner cleaner.

Avoid silicone dressings and greasy protectants. They can leave the surface slippery and create exactly the kind of glossy hazard nobody needs beneath the pedals.

Allow the liners to dry before reinstalling them, then verify the driver-side retention and pedal clearance.

Frequently Asked Questions

What vehicles fit WeatherTech 440031-440612?

The set fits select GMT800-based vehicles, including:

• 2002–2006 Cadillac Escalade EXT
• 2002–2006 Chevrolet Avalanche
• 2001–2006 Chevrolet Silverado Crew Cab
• 2007 Chevrolet Silverado Classic Crew Cab
• 2000–2006 Chevrolet Suburban
• 2001–2006 GMC Sierra Crew Cab
• 2007 GMC Sierra Classic Crew Cab
• 2000–2006 GMC Yukon XL

Exact trim and floor configuration must be verified.

Does it fit a 2007 Silverado 1500?

Only if it’s a Silverado 1500 Classic Crew Cab using the previous-generation GMT800 body. It doesn’t fit the redesigned 2007 Silverado.

Does it fit an Extended Cab Silverado or Sierra?

No. The complete 440031-440612 combination is listed for select Crew Cab trucks. Extended Cab models require a different rear liner.

Does it fit a standard Cadillac Escalade?

The supplied application specifically identifies the Escalade EXT. Do not assume compatibility with the standard-wheelbase Escalade or Escalade ESV without checking WeatherTech’s vehicle selector.

Does it fit the Chevrolet Tahoe?

Although front liner 440031 may fit certain Tahoe configurations, the full 440031-440612 set isn’t automatically correct. Verify the rear liner separately before ordering.

Does it fit a manual-shift four-wheel-drive truck?

Not if the truck has a floor-mounted transfer-case shifter that conflicts with the front liner. Confirm the shifter and floor configuration first.

Does this set include cargo protection?

No. It only covers the first and second passenger rows.

Can the liners be placed over factory mats?

No. Remove every existing mat and install the FloorLiners directly against the original carpet.

Final Verdict

WeatherTech 440031-440612 offers strong first- and second-row protection for select crew-cab GMT800 pickups and related full-size SUVs. Its molded edges and drainage channels provide considerably more containment than ordinary carpet mats.

The product itself is simple. Identifying the correct GM body style is the real job. Confirm the cab, floor shifter, model and whether a 2007 truck carries the all-important Classic designation before ordering.
