Dating back to the early nineties, the Yukon has been GMC's flagship SUV - and in particular, the Denali models which are their most luxurious offering. Big and tall, the Yukon was designed as a large-capacity passenger carrying vehicle that could also double as a serious tow vehicle. Initial versions of the Yukon were very truck like, using a body-on-frame design, a boxy appearance and a live rear axle. While still using a body-on-frame design, the modern day Yukon has come a long way since and is now sporting an independent rear suspension. As the years progressed, style trends have slowly evolved to feature more rounded and flowing body design patterns. While still keeping a bold appearance, the overall look is less truck-like and features significant aerodynamic and road noise improvements. In terms of powertrain, the Yukon has always been offered with V8 engines available, with most of the production years only having a choice of V8s. Broad torque curves and good peak power numbers from the slew of Vortec and EcoTec V8 engines that were used over the years has always ensured the Yukon a good towing capacity and surprisingly stout acceleration. Lately, GMC is really pushing the luxury aspect of the Yukon but yet has not forgotten its roots. This is evident with the release of the AT4 package, a first ever off-road oriented package that debuted for the Yukon just as of 2021! With aftermarket lift kits, skid plates and all-terrain tires having always been available, GMC finally officially gave nod to the Yukon's ability to be used on the trail, with all the aforementioned being part of the factory AT4 edition. As GMC has continuously researched and updated the Yukon, so too has the aftermarket kept pace.
