I've have a 4 dr sport with 305/65/r17 extreme a/t and a 2" body lift. A friend of my is pulling his coils and shocks off his 2011 4 dr rubi w/ tow package and giving them to me. With the coil and shock swap would I see any ride or height gain? Is it worth the time to swap them out?

 

I couldn't speak for an Unlimited, but I swapped a set of those same springs onto my 2 door Rubicon at one point. They gave me about 1" of height over my 2 door Rubi springs. The time spent in my case was worth it. Some might not do it for that result. They will have a little more height and weight capacity than your current springs. IMO

 

That's a good looking jeep....

 

See link for some info on this. You will need to determine the number of each coil and decide if it's worth the swap. I did this (went from a 14 to 17 front and 55 to 59 rear) and gained about 1.5 inches.

Definitely do the shocks as it's very worth it. Ride is much better with the rubi shocks!

+1 on that. The springs will give you a little lift, but the shocks are well worth the 30 min it takes to swap them on. They are a little stiffer overall, but really help with body roll and diving while braking. I absolutely HATED the stock X/Sport shocks that came on my Jeep. I swapped them over to Rubi takeoffs after about 10k miles and it was very worth the small amount of effort it takes to install them
