My spacer blocks below the rear springs are about 4 1/2". What I would like to know is the axle to frame spacing. I measured my spacerblock bump stop to the rubber bump stop. It measures 3 3/4" not a whole lot of travel, Maybe my springs are worn? These measurments are with a near empty truck (a sheet of plywood and some trash)? any other's measurments would be appreciated, Cheers.
