Product details:

Westin platinum 4 inch oval wheel-to-wheel step bars offer truck owners a commercial grade quality step surface that spans the length of the vehicle and features a third step area to facilitate access to the truck bed. They feature a unique patent pending isolator bracket that supports the step bar past the truck cab on long bed applications, a feature that competitors do not offer. Without an isolator bracket, the step area that extends past the vehicle cab is left unsupported. Additionally, westin's isolator bracket bushings act as a cushion for the natural flexing and independent movement that occurs between the cab and the bed mounts during driving, thus eliminating squeaking. Applications are no-drill and that's just another reason why installers prefer westin.
