EDIT : The original springs that I would lose under flex were my stock 4 Runner springs. The FJ's are all longer... I used a '13 FJ spring
I switched up to the longer spring FJ spring as the original springs would come out of the perch when in flex...
Hello. So in using stock springs with the 5100's the rear springs come loose??!! Are others having this issue? I'm looking at doing 5100's front and rear with stock springs (08 V8).
