I have a flat fender with a 2 1/2 inch rancho spring over, but its not flexy. I heard some wrangler leaf springs will make it flexy. I dont know which wrangler spring to get. I also want the spring to match my lift.

can anyone help ...thank you

i have yj springs on the rear of my cj. i don't know what year but i think they are all the same. when i first tested them in a spring over configuration, the axle wrap was so bad the rear tires almost left the ground when shifting from 1st to 2nd. i had to build a traction link. i've heard they break easy but i've beat the crap out of mine and they've held up. they're great but as with any soft leaf spring, you're going to have to address the axle wrap issue.  

contact Holbrook longleaf springs. They have it dialed in for flatfenders.
