I recently bought a 95 Scrum 4x4 and put the dump system from my 2 wd Mitsubishi on it.The way it all ended up the mounting bracket for the dump cylinder ended up farther back and directly over the differential pumpkin and with a heavy load sat right down on it.I did a google search for overload springs and Amazon had some for $36 and free shipping.I had to take the stock springs apart and install this one between the 2nd and 3rd leaves,not a big deal,and they work great.With a big load of dirt there is now a good 2" clearance.It's a little stiffer ride but for me that's not a problem.All and all a great deal if you need a little help with heavy loads.
If you go to Amazon and search overload springs they will show Superior part #11-1040, they are rated 2000 lbs.You will need to take your existing springs apart to install them and replace the center bolt but it's not a big deal.These lifted the back of my truck about 3".For the money you can't beat them.
