- Allows for no-trim 20x9 0 offset on a 35x12.50 tire.
- *Max with trimming: 20x10 -18 offset - 35x12.50. Some fender well trim variances may be experienced between Silverado and Sierra models.
Special Note: When setting the torsion key adjustment bolt do not exceed 27” from the wheel center to the fender edge. Exceeding this will overlift the vehicle creating a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components. Max width on stock wheels is 11.5".
