Trader's, a name that's been around our industry for as long as we can remember and sells just about any truck part you can fathom, now offers a line of lift kits to pump up your GM truck. The company's kits come with all the necessary parts, from lift spindles to tubular upper arms, to complete the job.

The cast-iron lift spindles provide 3 inches of lift, while the new springs add an additional 4 inches. The control arms are constructed of DOM tubing and come with the ball joints installed. To install this kit, you'll need to weld the carrier bearing mount into place and cut off the factory bumpstop; it'll take a little more than just sockets and wrenches to put it all in. Luckily, the rest of the components bolt in using most of the factory hardware.

Because we wanted to complete the look, a larger wheel and tire package was in order. This lift should provide enough clearance to run 32-inch tires without any problems - maybe even 33s with some body trimming.

We used a set of Welds' Velocity 6 wheels from the EVO line; with a forged one-piece design, they are extremely strong and have a five-layer chrome finish to make maintenance a snap. We wrapped the rims in LT325/60R18 Nitto Terra Grapplers, a 33-inch tire featuring a balanced void ratio for excellent off-road traction and on-road behavior.

The kit also comes with a limited lifetime warranty on all the parts and takes only a few hours to install. We went to Trader's to watch Richard Pineda, master install guru, put all the parts on this previously lowered truck.

Converting Metric Tire Sizes To Inches
Example Tire Size: 325/60r18
The first number on the tire is the total width in millimeters, measured from sidewall to sidewall. To convert to inches, divide by 25.4. For the example tire, the width is 325 mm, or 12.80 inches. Overall width: 325 (mm) / 25.4 (mm per inch) = 12.80 inches wide.

The second number is the aspect ratio. This is the ratio of sidewall height to width. In the example above, the tire is 325 mm or 12.80 inches wide, so multiply that by the aspect ratio 60 (percent) to find the height of one sidewall. Section height (sidewall height): 12.80 inches x 0.60 = 7.68 inches high.

The last number is the diameter of the wheel in inches. To figure the diameter of a tire, take the sidewall height and multiply by 2 (remember that the diameter includes two sidewalls; one above the wheel and one below the wheel), then add the diameter of the wheel for the answer. Overall diameter: (7.68 inches x 2) + 17 inches = 33.36 inches tall.
