Yes, you certainly can! Each rate change is subject to specific guidelines.  We recommend reaching out to your dealer for all rate change requests.


What are the maximum rerate limits for an Iron Bull or Norstar trailer?

· Maximum derate amount: 30% of overall GAWR

· Maximum prorate amount: 20% of overall GAWR

· These amounts may not be possible on all trailers depending on the limits of components on your trailer. If the trailer has a 15k bumper pull coupler, we cannot prorate any higher than these limits.

Can a used vehicle be rerated?

· Not by Norstar. Certification and ratings assignment apply only to newly built trailers. Once a trailer has been licensed and titled by an owner in any given U.S. state or sold and delivered to a purchaser at the first retail level in a Canadian province or territory, the certification obligation ends, along with assignment of ratings. 

· Some states do allow rerating vehicles through the local DMV.

Can axles be added to increase GVWR?

· This would be determined on a case-by-case basis. Depending on the build quality of each specific trailer, and what testing each trailer has been through.

 The drive-over fenders are built to meet the payload of your trailer when the weight is evenly distributed.
Each Iron Bull or Norstar Trailer has a VIN tag that is placed on the driver's side of the trailer.  On a Gooseneck trailer, it is inside of the riser. On a bumper pull trailer, it is on the lower subframe behind the tongue.
