Shackle Length of Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00

Question

Question:

My trailer has axle spacing that is 35” with 26” springs. I would like to get the Dexter HD shackle and equalizer kit but it only comes with 2 1/4” shackles and mine are 3 1/8”. Will it cause a problem if I change them over?
