I use my Big Bear for hog hunting pretty much every weekend and it's time to replace the rear suspension. Once it gets pushed down it doesn't come back up. I haul dogs on it a lot of the time when I hunt and sometimes(hopefully) some hogs too. My question is, is there a heavier shock and spring I can use than the stock stuff or is that the only option I'm going to have. I don't ride it all that fast or rough, but I do ask it to carry about 140 lbs pretty regular.

This is the rig I've got on it.
