Age is but a number, and this certainly holds true when referencing 1999-2006 GMC Sierra pickup trucks. By now, it is certain that most of these first-generation Sierra trucks have a few miles on them, but it does not mean these venerable workhorses are tired. Rather, the aftermarket upgrade market has never been larger or easier to access, thus customizing your 1999-2006 Sierra can be fine tuned to your exact need and taste.
Tow and haul easier by upgrading your 1999-2006 Sierra’s engine performance. With the revered LT-based Vortec V8 as the heart of most models, producing more than stock power is made ridiculously easy thanks to their affinity for aftermarket intakes, tuners, camshafts and exhaust systems. If you need more than a 100 horsepower gain, consider a supercharger or turbocharger setup. Complete plug-and-play systems are available, and with a heavy duty, 6-bolt main iron block (or aluminum block for special edition Sierras), these engines can handle the power.
When on the road, make your ride more comfortable to tow with by upgrading the suspension system with a set of rear helper springs or air bags and heavy duty shock absorbers all around. Big tires, an LED light bar and a lift kit will help to get your off-road adventure started. And if you’re really serious about off-roading, there are plenty of aftermarket options to help protect your Sierra when out on the trail. Skid plates, fender flares, bull bars, reinforced bumpers – the sky is the limit in terms of transforming a first-generation Sierra into an off-road beast.
