The ICON 2" bump stop spacer kit drops OE rear bump stops of 05-24 F-250/F-350 by 2? to limit up travel for fitment of certain suspension components, or ensuring clearance of larger tires when the suspension is fully compressed. The CNC aluminum spacers are also useful to ensure proper bump location when deleting OE rear leaf spring blocks when installing new rear leaf springs or if a shorter than OE block without a bump stop tang is desired.
