everyone always hating on blocks . . i had mine with 1 ton rear, 4.88's and 44's and never had much of a problem . .never kicked em out but did twist the rear springs with the 454 . . .


also another option is do the 52 inch spring swap to the front . . stock rear 52's will give ya about 4 - 4.5 inches of lift with 6 inch springs it should give ya 10 . .and then just buy 10 inch springs for the rear

check out diy4x.com he has the front spring mounts for swapping in 52's
