When installing the 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles # e48SR I recommend using one of the kits below depending on the amount of axles you have and the length of the current straps. While the length does not have to match exactly you will want it as close as possible to maintain your current ride height.

MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" # MR46ZR
MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" # MR76ZR
MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track - 2-1/4" # MR58ZR
MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track - 3-1/8" # MR98ZR
