First, thank you so much for providing all the axle information on your 2007 Fleetwood Redline 33. The 4-Leaf Double-Eye Spring # e47SR is our closest match to the Lippert 702096 leaf springs that came on your trailer. Both are 4 leaves and the Lippert has a loaded length of 26" while our measurement of 25-1/8" is the unloaded length. You will want to replace all 4 leaf springs at the same time to ensure the suspension system under your trailer behaves properly. view full answer...
