Hey Derek, thanks for getting us the length of your springs. When picking out a replacement leaf spring you want to go with one that is slightly shorter in length than what you have now without the weight of the trailer on it. So based on that the correct length from a new spring would be 25-1/4 inch like the part # DX23CR.
