The 5-5/8 inch E-Z Flex Equalizer in part # K71-652-00, have a capacity of 3,000 pounds (6,000 total for the whole system). The 7-3/4 inch equalizers in the Triple Axle Kit, # K71-657-00, have a capacity of 4,000 pounds (16,000 pounds for the whole system).

When I did a little research on your 2007 Keystone Raptor 3814, I found that it has a dry weight of 11,525 pounds. If the existing equalizers have the same ratings as the E-Z Flex models, then they have a capacity of 12,000 pounds (using two 7-3/4 and two 5-5/8 inch equalizers). By replacing the entire system and using 7-3/4 inch equalizers included in the triple axle kit, # K71-657-00, the equalizers will have a capacity of 16,000 pounds.

You will have to determine if there is space enough in your suspension system for the longer equalizers. It could be that the shackles in use by the 5-5/8 inch equalizers are longer than those used by the 7-3/4 inch equalizers thus compensating for the shorter equalizer. Measuring will be the only way to determine that.
