Can You Install Longer Shackle Straps on Single Axle Trailer for More Lift

Question:

I have a single axle BigTex trailer. The leaf springs currently have 3 1/8” shackles. I would like to put longer shackles on to gain a little more clearance to the frame. Do you have or can I buy a shackle the is 4” center to center. My bolts are 9/16”. Thank you,

I do have an option for you but changing the shackle strap length will change the whole suspension geometry so that's not recommended unless changing other components such as the leaf springs. Furthermore, 3-1/8" is the longest length used on most trailers. I instead recommend using a leaf springer hanger extension kit like the Correct Track Trailer Alignment and Lift Kit part # LC87120 which will provide a lift of 1-1/4" or 2-1/4" as well as correct a misaligned trailer axle if present.
