BDS 2" suspension lift (springs and shocks). Gave me approx. 2.75" of lift, leaving plenty of space / clearance for my tires. Required no other parts or additional expense. Quality parts, rides like stock.
This system has worked great for me. Keep in mind I'm in Florida, my Jeep is for weekend fun, I like a smooth highway ride, and I use it for exploring wooded areas and the Beach.
Keep it simple, and good luck with whatever you purchase.
