The PSC SK339 Big Bore XD Steering Kit is a massive upgrade for the steering system in your GM Silverado/Sierra 2500/3500. This all-inclusive kit comes with a PSC-tuned PSC BIG BORE XD Steering Gear Box, a premium high-pressure hose kit, an extreme-duty idler arm, and an extreme-duty 4-spline pitman arm. Also included are two bottles of PSC 715 High-Performance Power Steering Fluid to fill the OEM-style reservoir with a cap. The larger ring and rotor in the gearbox produce more flow at lower RPMs and the 1800 psi pressure relief valve helps turn larger tires.
