The Chevy K3500 is a full-size pickup truck that was designed with a full ton of weight. This vehicle is also a four-wheel drive, so with the added weight, off-road driving is quite possible. In fact, this truck was designed to be able to drive in the ice and snow with ease. As the years progressed, new upgrades became available, and in 1991, the 4L80-E automatic transmission was released on this one-ton truck. Extended cabs with side steps were also available during the fourth generation.CalTrend is the leading provider of X leather seat covers.
