Upgrade front suspension for plow?

I have a 2011 XUV 825i. Just bought SnowEx 6' plow. Front suspension squats excessively. This plow is heavy. Front shocks are already adjusted to the max. Nothing heavy duty offered by Deere. Fox 2.0 retails +$1,500! Have tried local Deere dealerships, the plow dealership, the plow mfg'r, local ATV/UTV performance shops. No one seams to have an answer for shock options besides spring spacers or the Fox 2.0.
Anyone have experience changing the front shocks for beefy'r??
