Looking to upgrade the brakes on my 05 dually that carries a Lance 1172 truck camper with a dry weight of 4500lbs so good brakes are a must. One of the items to upgrade was to change the flexible brake lines to stainless steel version. I found the Russell Performance kit 672440 that's for this truck except it wouldn't fit the dually version, same thing with Crown Performance. The rear calipers are the issue with both these kits.
Anyone out there have any experience with this?
