Hey guys getting read to do my lift and axles on the Burby. I bought some slightly used 4" front springs with new Rancho shocks and steering arm off a buddy. He didn't have the 4" blocks for the rear, and my stock springs and bushings are soooo bad back there I wouldn't want to do a shackle flip either. I want to get some good 4" lift rear springs....who has the good ones at a good price? Will 4" springs in the rear still make the Burby sit ass low? Should I go with 6" springs in the rear? Thanks for the help.
