So I took my jeep to Firestone to get an oil change and they did a free checkup... After 8 hours of waiting the manager called me over and told me he had to show me something. He took me into the garage and showed me my jeep's springs. (I believe I have a 2.5 inch lift, teraflex). He told me that I have a lift and that the stock coil springs are still on the car and are way to loose. He then demastrated how lose by lifting the car up off the ground and taking the rear cool springs off with one hand.
Could this be bad?
The manager stated that it could fly off if I hit a bump.
I also noticed that my friends lifted rubicon 2 door has a 2.5 inch lift and is wayyyy softer on hitting bumps offroad. My suspension feels hard, could this be why?
And should I buy new coil springs?
You say you have a 2.5" lift. Is that a spacer lift or a spring lift? If its spacer it does not surprise me. Your shocks are too long. If its a spring lift something is fishy. I have to detach my shocks, trackbar and even sometimes lower CA's to get my springs out.
Completely depends on what you have. Stop asking questions without providing information. Do you research and you will get 99% of all your questions answered. You say in the first post that you might have a 2" lift, but in your profile you say 4".
