GMC debuted the Yukon in 1992 to help take the place of the K5 Blazer. Sitting atop GM's GMT400 platform, the Yukon was a true truck capable of hauling a trailer, a hefty payload, and the entire family making it a very versatile successor to the K5. Nowadays, the 1st Generation Yukon is still capable, but we have the parts to take it to the next level.
