most likely, yes, and if I do and I like the WSI HDs I'll pull the back bracket or pull the bolt and have it spot welded. this is all TBD
On another note, when i called to order the HD springs, I spoke with Jimmy and he suggested going back to the OEM shackle instead of the drop shackle I have in there now (that came with the WSI SDs)
Heathers truck runs the WSI SD springs with the stock shackle. The front and rear sit almost exactly level.
So the orignal setup on the trucks was.
GLRE-001 WSI HD Springs and 2" drop
GLRE-1.5 WSI SD Springs and synergy 1.5 drop
The 2" rough country shackle bushings where toast.
At that point the springs had settled probably about .5-1 inch.
So I put the synergy on GLRE-001 and the stock back on GLRE-1.5. If you want to know the noticeable difference its 0. The difference is so little that I don't think heather even knows there was a change.
