What does a Suspension Lift Kit do?

Clearance. For starters, one of the foremost reasons for installing truck suspension lift kits is to raise the height of your ride off the ground to enable steeper ascent or descent off-road, and higher ground clearance. In general, it makes sense that when driving over boulders, slogging through mud, coasting across the desert, or even just making your way through the occasional forest trail, higher clearance facilitates negotiating certain obstacles. This can often be a tricky bit of artistry to manage, as higher clearance also raises your vehicle’s center of gravity, which can reduce handling.

Larger Tire Fitment. The general consensus suggests that larger tires equate to more traction, right? Well, not entirely. While larger tires may provide some improvement to traction in off-road conditions, there are other ways to improve a vehicle’s traction that are far more efficient than simply bulking up the rubber. Aside from the obvious stylistic discretion, the main reasons for adding larger tires are for higher vehicle clearance for improved performance in mud, deep snow, rocks, and deeply rutted trails. Certain tires designed specifically for off-road conditions can improve traction depending on the circumstances, but the added clearance is the most immediate and direct benefit of larger tires.
