Is it possible that our spring helpers have simply worn out over 11-13 years and gotten stiffer? Any comments from original owners? I started with stock springs and went to OME 912's and get the same jaring with both of them making me think that my helpers were never sitting directly on the axle (but that's just a guess...) I get their purpose but they just seem way to stiff. I'd like to cut them but I might try new shocks first and see what that does.
