Closely related to the Chevrolet Silverado HD pickups, Sierra HD models combine segment-leading power with super-strong chassis and advanced suspension systems to provide professional grade work capabilities, exceeding the toughest requirements and expectations of heavy-duty customers. For example, both the Vortec 8100 and Duramax 6600 provide 12,000-lb trailering capability with either of their available transmissions. The lineup includes a wide selection of 3/4- and one-ton Regular, Extended and Crew Cab models, available in 2WD or 4WD, short box, long box and chassis cab configurations.

The heavy-duty lineup’s new vocational trucks, the Sierra Professionals, are available in 2500HD 2WD and 4WD Extended Cab short box configurations (C/K25753HD) with a 9200-pound GVWR. They’re custom-designed to expand the work capabilities of contractors, builders and numerous other tradesmen who carry equipment and/or are prone to use their trucks as portable offices.

The Sierra Professionals will be introduced in the fourth quarter of calendar year 2001.

The Heavy-Duty Trailering option adds an adapter that permits four-way, as well as seven-way, trailer harness connections.

All heavy-duty models feature the larger "Sierra" rear tailgate badges, first introduced on the Sierra Denali, as a bolder expression of their unique 'Professional Grade' character.

Exterior Design:
Visually, the new Sierra 2500HD Professional models are distinguished by their molded-in-color bodyside molding, embossed with "Sierra Professional" in raised letters. They also have a full standard bedliner and top rail protector covers. Both 2WD and 4WD models also feature wheel flares. The trucks are available in all regular 2500HD extended-cab colors, except Toreador Red.

Heavy Duty Sierra trim changes for 2002 include:

Revised SL trim that now includes standard equipment like an AM/FM radio with CD player. The audio system with CD player, which replaces the previous cassette, is now also available as a freestanding option; it does not require luxury trim.

Revised SLE trim, adding standard items like deep tinted glass and electrochromic mirrors with a temperature gauge and compass

Revised SLT trim, with additional standards like fog lamps and options like a Cold Weather equipment group

Interior Design:
The Sierra Professional's interior features a full-length, custom-designed console, extending from the instrument panel to the back of the front seats, along with a unique rear under-seat storage container. Both storage facilities lock for full security.

The center console has a front compartment, providing concealed storage for a PDA (personal digital assistant), cell phone and two auxiliary power points to charge them. It also provides a storage tray for smaller items like maps, gloves or CD. In addition, it has an oversized "Big Gulp"-type cupholder and a second temperature-controlled cupholder that can keep beverages hot or cold, when the ignition is on. The center console also accommodates a seven-quart capacity, thermal electric cooler, provided with the ensemble, which can keep drinks and food cold or warm. The cooler runs directly off the battery and provides power continuously, even with the engine off. It uses a smart switch, which monitors the battery charge level and shuts power off, when necessary, to preserve the battery.

The center console can also be easily converted to provide hanging file folder storage, with two specially designed rails provided for that purpose. The rails slide into the center bin in place of the thermal electric cooler. Additional storage capability in back of the console accommodates items like folders and portfolios. Convenient storage nets on the underside of the lid and on the backside of the console provide additional storage. The console also has two additional power outlets in the rear for charging battery packs for power tools.

The lockable storage container beneath the rear seat is approximately 57 inches wide, 16.5 inches deep and eight inches high, providing a little over two cubic feet of storage space for larger vocational tools like rotary hammers and saws. Inside, it provides another 13.5-inch x 12.5-inch x 5.5-inch storage container for smaller items like electrical components, fasteners or plumbing repair items.

The Sierra HD’s optional Duramax 6600 turbo diesel V8 adds a new exhaust gas recirculation cooler and other minor modifications. The Duramax 6600 now provides LEV capability for all Sierra HD pickups sold in California, with both the standard ZF S6-650 six speed manual and the optional Allison 1000 five-speed automatic transmission. The trucks’ GVWRs range from 9200 to 11,400 pounds. The Duramax 6600 now also delivers the same maximum 300 horsepower at a lower 3000 rpm; its awesome 320 lb-ft of maximum torque at 1800 rpm is unchanged.
