So I just wanted to update everyone on how I like the rear 4" leaf springs from Ujoint. If anyone has been following this thread they more than likely forgot I even purchased them and told everyone I did back on April 18th but they finally arrived to me this past week. Yes that almost 3 month stretch felt like 3 years but the wait was totally worth it.
Since replacing the stock springs and block with these it made me more aware of the amount of axle wrap I was suffering from. Once I put these on all of the stopping and clunky rear end I was feeling before was gone and now I feel more than solid. I also didn't realize how much squeaking and noises were coming from just the rear and now that thats gone its amazing how much quieter it is cruising around.
BUT THE BIGGEST BENEFIT has been towing. I had another post asking about a rear sway bar and asked Chris if he had one and he said he didn't. Now I know why, just putting these springs on has made towing so much easier. I don't feel like the trailer is back there giving me the business anymore but actually feel like its one with the van, like towing should feel like.
Overall I am very impressed with the ride and would totally recommend anyone that has blocks to ditch those things and get some springs from Ujoint.
