Well i am putting one tons under my dodge 1500 short box single cab. i currently am running SJ 7" lift springs up front. i plant to keep the parallel 4-link with track bar. the delima is i want to use some smaller diameter springs for the build due to the close clearance from the chunk to the inner c on the ford HP d60. i will not do coilovers because all this thing sees is mudd.. where can i get some smaller dia springs in a rate heavy enough for the fullsize? would a 3" coil over spring work??
