So I ran 48", 52" and 56" front springs. In the rear I ran 56" and 63" springs. The best combo by far was 56" springs all around. With the 52" spring swap you have to move the rear shackle and all that jazz. I also wasn't impressed with durability of the 52" spring. Although I see Kert from DIY4x says you dont have to depending on which hole you use... To be honest I got a lot of flex from 48" springs and I think if it were me, I would go with ORD new front springs and a beefier longer shackle and be done in front with DIY4x knuckle shock mount. With 56" springs I bet you could use the front hole of the b52 and keep the shackle in the factory hole, and get 1-2" of wheelbase stretch. I used a custom hanger so I cant guarantee the b52 would fit the 56" spring.
In the rear, I ran the 56" springs with a shackle flip and they were great, I went to 63" springs cause the internet says they are awesome....they do ride soft, but I bent them because there is so much unsupported ply. I also go hung up on the leading spring hanger on the 63, when that never happened with the 56" springs....
