I saw this on pirate4x4 in the Toyota section, wow!
I recently bought a set of 5 inch front allpro springs for my 98 tacoma. I just had the swap done professionally about a month ago. After about a week of street driving the drivers side springs settled 2 inches more than the passenger side. The truck now leans about 2 and half inches from the passenger side to the drivers side. I called Allpro and told them the situation. They told me to send them some digital picture which i did. I called them later about the pictures. They told me that my sas was done incorectly. I asked him how and he told me that i had no bumpstops. He told me that their springs can settle like this even street driving and going through gutters. My case is the springs are obviously faulty and they dont want to back their products. Normal street driving for a week should not cause this to happen. I have given them lots of bussiness over the years and this is how they treat me. One more thing to add is When i was on the phone with Allpro they hung up on me and they said they couldnt talk to me anymore.
Basically Allpro and their springs suck!!!!!!!
I will try to post some pictures later proveing my claims
