From what I can tell they are just stock springs in the front.. but it was level with the three inch block in the back with stock back rears springs... my problem was stuffing the 35’s when turning while wheelin and stuffing the rears with my gear fully loaded when goin camping or wheelin.. I kinda like the travel in the back now...my thought was with the 47’s up front it will move my axle forward bout an 1”- 1 1/2” ?? not sure exactly the distance, then just get the correct amount of spring lift in the front and level it out.. If I pull the blocks will I stuff those 35’s in the rear again fully loaded? What are your thoughts on the best way to find out the amount of lift needed in the front springs?
