Already have a set on my 2006 Grand Caravan and works well. $150 for the pair obo. "Monroe load adjusting shock absorbers adjust rapidly to changing road and weight conditions, delivering enhanced control with uncompromised ride comfort. They offer superior comfort for normal driving and deliver extra control when operating conditions get more demanding. These units also include a heavy gauge calibrated spring for extra control and comfort. A new pair of Monroe load adjusting shock absorbers can assist in maintaining ride height when up to 1,100 lbs. of additional weight is loaded. These units are ideal for light trucks that carry varying loads or tow trailers."
