Sierra 2500/3500 Parts
United under the General Motors manufacturing label, the Silverado and Sierra have been running parallel on the assembly line since 1962. Change has been a constant for both trucks throughout the past 50-plus years, as both the Silverado and the Sierra have undergone a host of refreshes, redesigns, and generational shifts during that time. Despite all of the many innovations that have risen up in the past decade, GM never shied away from its roots and constantly churned out trucks that were tough and reliable.
The Chevy Silverado vs. GMC Sierra debate has raged on since the early 1960s, but both pickups have been popular amongst the American worker population for generations. Many of the differences between the Chevy Silverado & the GMC are small, but the two behemoths have devolved passionate fan bases over the years, and both rigs are versatile enough to handle most on and off-roading needs.
The GMC Sierra, in particular, is known for its reliability, longevity, and workhorse-like mentality, but sometimes, depending on the task, you need a little extra strength to go the distance. In response to the growing demand of contractors and laborers, as well as Chevy’s new HD truck initiative, in 2001 GM launched its own Heavy Duty truck line that included both the Sierra 2500HD and the Sierra 3500HD pickups. These powerful rigs combined all of the many luxuries of the Sierra’s past with a blue collar attitude that was capable of getting the job done.
Before we delve into the many GMC Sierra 2500 HD and Sierra 3500 HD parts on our online catalog, let’s take a closer look at the brief, yet meaningful history of these vehicles.
GMC Sierra Heavy Duty Trucks: The Beginning
In any great sibling rivalry, any action is followed by a greater reaction, as the friendly adversaries often look to one-up each other. This also rang true for the Silverado and Sierra trucks. Shortly after the dawn of the New Millennium, when Chevrolet threw its hand in the race to produce the best Heavy Duty truck on the market, GM introduced another competitor in the form of the Sierra 2500 and 3500 HD pickups.
The 2001 reintroduction of the GMC Heavy Duty pickups replaced the long-standing three-quarter and one-ton GMC Sierra models of yesteryear and immediately positioned General Motors (as well as Chevrolet) alongside its rivals from Ford and Dodge. The 2001 GMC Sierra 2500HD proved to be a more upscale and luxurious version of its Silverado HD counterpart, by offering a plethora of modern amenities, including daytime running lights and passenger airbags among others.
GM fans could purchase a new 2001 GMC Sierra in either regular, extended, and crew cab body styles, as well as two or four-wheel drive options. In 2003, the Sierra 2500HD received several exterior upgrades, including an aggressive front fascia and a slightly modified rear area. GM further updated the truck’s body in 2005, and Sierra fans could choose between several trim levels, including the SL, SLE, and SLT options among others.
The interior provided a comfortable ride for up to five passengers, depending on which cab that you select, but the real innovations that got people talking could be found under the hood of the GMC Sierra 2500HD pickup. The inaugural line of GMC Heavy Duty trucks was powered by a standard 6.0L V8 motor. Paired with a five-speed manual transmission with overdrive, the large V8 motor paved the way for the 2001 GMC Sierra 2500HD to put down 300 hp and 360 lb-ft of torque.
If you owned a First Generation GMC Sierra 2500HD and wanted to put an extra pep in your truck’s step, you were free to choose between an 8.1-liter gasoline V8 engine, which produced 340 hp and 455 lb-ft of torque, or a 6.6L turbodiesel motor that churned out 300 hp and 520 lb-ft of torque. The diesel engine received a number of upgrades throughout the Sierra HD’s First Generation, including the addition of more power and the reduction of emissions in 2006.
For the 2006 GMC Sierra 2500HD, the 8.1L turbodiesel engine made 360 hp and an impressive 650 lb-ft of torque. Also in 2006, GMC Sierra Heavy Duty truck fans could enjoy an all-new six-speed manual and automatic transmission options. The steady improvements made to the vehicle throughout 2001-2006 combined with the many aftermarket GMC Silverado 2500HD parts available gave the American truck community plenty to talk about and laid the foundation for greater success in the coming years!
The Second Generation: 2007-2014
As was the case with the Chevy Silverado, the GMC Sierra underwent a major facelift for the 2007 model year. Like previous years, the 2007 GMC Sierra was available in a trio of different body styles, including standard cab, extended cab, and crew cab, as well as in both two and four-wheel drive.
The many body styles called for different trim options, including SLE or SLT. All of the various trim packages contained a number of the popular interior innovations of the time, including advanced audio systems, heated seats, wiper sensors, and remote starting capabilities, depending on which level that you favored at the time.
Like most new generations, the 2007 GMC Sierra 2500HD underwent a host of changes throughout the vehicle, highlighted, of course, by the modified engine compartment. A muscular 6.0L V8 capable of producing 353 hp and 373lb-ft of torque came standard on all 2007 GMC Sierra 2500HD trim levels, but as was the case with previous editions, there was a diesel engine option that was practically begging to be unleashed.
The standard motor was great, but GMC fans were free to select the now-famed Duramax 6.6L turbodiesel V8, which could max out at 365 hp and a whopping 660lb-ft of torque. The burly motor came paired with an innovative Allison six-speed automatic transmission. Power is always the name of the game if you own a Heavy Duty pickup truck, and a fully equipped 2007 GMC Sierra 2500HD could haul up to 3,458 pounds and tow up to 13,000 pounds.
For the 2011 mid-generation refresh, however, General Motors raised the bar even higher. Sporting a revised, turbocharged Duramax motor, a 2011 GMC Sierra 2500HD boasted a towing capacity of roughly 17,800 with a fifth-wheel hatch, making it the ideal rig to bring your boat, trailer, or anything else heavy along with you! Speaking of the 2011 GMC Sierra 2500HD, the new-look Heavy Duty pickup came equipped with a sturdier frame, a modified suspension, and a slew of driver aids in which truck enthusiasts grew to know and love.
The 2011 GMC Sierra 2500HD’s new boxed frame increased rigidity and durability and offered a much smoother ride when the new suspension components were factored in. With its steadier ride, impressive performance towing stats, and improved fuel economy to go along with it, the changes made to the 2011 Sierra HD marked a big step in GM’s quest to build the best Heavy Duty truck on the market. The excellence continued in 2012-2014, making the GMC Sierra 2500/3500’s Second Generation a roaring success!
2015 & Beyond
As it has done all throughout its illustrious history, General Motors remained on the cutting edge of societal evolution for its Third Generation of Heavy Duty pickup trucks. The Third Generation drew a line between the 2500HD and 3500HD rigs, as the GMC Sierra 3500HD featured a dual-rear-wheel axle. For the 2015 redesign, GM implemented many aesthetic, performance, and customization features, including the addition of the double cab model.
The double cab was a happy medium between the regular and crew cab body styles, which was a welcomed changed for many Sierra fans. Regardless of which style that you selected, you were certain to enjoy the newly-designed, luxurious and spacious inner cabin. The state-of-the-art interior featured beautiful stitching above the dash, along with large easy-to-use dials for the accessories, such as the climate control and radio volume.
Much to the delight of parents everywhere, 2015 GMC Sierra 2500HD pickups left the factory with some of the latest safety features, including antilock disc brakes, traction and stability control, front-seat side airbags, and full-length side curtain airbags among others. Furthermore, OnStar technology provided automatic crash notification as well as roadside and stolen vehicle assistance. Additionally, the Third Generation GMC Sierra Heavy Duty pickups featured front and rear parking sensors to help drivers fit that gigantic rig into a small space.
As far as the engine goes, a 6.0L, 360 hp, and 380lb-ft-producing V8 motor comes standard in the Third Generation Sierra 2500HD pickups, but as always, GMC owners have plenty of flexibility. Sierra drivers have the option to add bi-fuel option to the engine, which allowed the vehicle to run on either gas on CNG. For the diesel fans out there, an optional 6.6L V8 that could put down 379 hp and 765lb-ft of torque was available. With new upgrades being introduced every year while maintaining the same impressive payload and towing capacity stats, it is clear that the GMC Sierra 2500HD and 3500HD trucks are not going anywhere anytime soon!
