Will a 160 tire fit a 2005 heritage classis with a 2"lowering kit on the rear

The front under carriage has what is called a main drag link, it ties from one wheel

spindle to the other, the way to check it is to grab it with both hands if you can move

it and has lots of play, this is your problem. but if you did modifications to your truck,

you may have to purchase a modified version to correct the changes made to your

truck. if worn out can be replaced, but because of modifications you may have to go

with one that fits your truck . good luck!

lift rear gate, you will find a hole on lower right, right above bumper
take squarish rod end of one of the black rods that come with jack kit and slide it in hole and turn it clock wise until tire comes down. Do not use "j" side use square side.

30 psi front
36 psi rear (single rider)
40 psi rear (dual riders)

i did some checking and the lowering kits fit Silverado 1500 from 1999 to 2006
