Will 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles Flex When Weight is Placed On It  

I own a 2021 Grand Design Solitude 375RES Fifth Wheel with dual axles with MORyde CRE3000 that has been configured by Grand Design with 8k axles and disk brakes. I need to buy a set of replacement leaf springs and I thought that the Dexter DX74XR should be the right ones but the length measurement is different. According to your specs, it should have 24-7/8inch center of spring eye to center of spring eye but when I measure my 7 leaf double eye springs, I get 25-3/4inch while loaded. Unfortunately, I cant measure them un-loaded. The rest of the specs are similar: 7 x leafs, 3/8inch thick, 1-3/4inch wide. Could the discrepancy in length being one inch longer be caused by the fact that I measured the spring loaded? If yes, is the DX74XR Leaf Springs, the correct replacement on my 2021 Grand Design Solitude 375RES?
