I bought my 2005 TJ after it had been fitted with a Rough Country 97-06 Jeep TJ 3 1/4" progressive coil/spacer kit, 92PERF1641. It is extremely sensitive to any bump in the road. I need some good advice from someone who can help identify the cause and possible mods that will make it more drive able. I live in the Seattle area but haven't been able to find a shop that can help. If anyone knows of a place, I would appreciate your help. Thanks.
