Will 33 inch tires fit 199o Chevy 1500 pickup with no lift?

The increased available travel of the frontsolid axle most likely requires a 3 or 4 inch lift to both clear 33x12.5 tires and make best use ofthe available articulation. For the front, the torsion bars do need to be cranked up to raise the front end, approximately 1.5 inches. For the '89 to '95 trucks with no other body or suspension lift, this generally means that the measurement between the top of the rim and bottom of the fender should be 15" to 15.5" with properly cranked up torsion bars.

Aftermarket torsion bars, such as Sway-a-way's 25mm bars work great but are not absolutely necessary. The Sway-a-way bars increase the spring rate between 20 and 30 percent, which means the springs are about 20 to 30 percent stiffer than stock. This helps if the truck is equipped with a winch up front and also helps prevent the truck from bottoming out on rough roads.

There are some disadvantages however, that I discuss further down. I DO NOT recommend buying or installing any of the 26mm torsion bars, such as from Rancho or Downey.
