DAMN. Thanks for the info. Happen to know if another H/A spring fits on this beast?

 

I have seen some springs/ sleeves on ebay before, I'd say the stock springs are fine if you want to preserve ride/stability, but you can get some koni ajustables, or KYB oem replacements for a solid ride, w/ oem-like comfort. the kyb's are about 1/2 inch shorter so it keeps the springs tightly coiled, making handling very nice without dramatically lowering the vehicle.
