You have at least a 3/4ton or 1 ton truck & from looking at your truck in the gallery pics and from just looking at the springs & shackles. Those are NOT 1/2ton springs, shackles or bed, all are the same as 3/4 and/or 1 ton truck. If your springs are 54x1 3/4 you have a 3/4ton if they are 46x2 you have a 1ton...Joe
