Amount this 72 is lowered??

[Deuce26]

I could use some info from you guys on this. I want to put new coils on front and back because this thing rides like crap.. But I need some input on which lowering coils to buy to keep it the same ride height or maybe even a bit lower. Looks like someone heated the coils at one time to lower it and I can't stand the ride..I put new shocks front and back but it is still real bouncy. Thinkin about the jeep coils for the rear, any input on that would be great.

Thanks
