XHD Leaf springs in CA.

has anyone else used this JRS guy to buy springs?

do you just call them up and they'll give you the info on pricing and shipping?
thanks

and also a little tip that i heard from one guy is that if you have someway to load up the trunk with extra unneccesary weight, it will put extra stress on the springs and help them sit evenly. this doesn't seem right to me though. has anyone else heard this?

What!? Oh, sure, well I happen to have a couple bags of dry cement mix in case you are interested. Seriously, some things are just beyond the pail.
